CANADIAN ENVIRONMENTAL PROTECTION ACT, 1999

Notice of intent to develop greenhouse gas regulations for electricity generation in Canada

Notice is hereby given that Environment and Climate Change Canada intends to amend the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations and to develop regulatory requirements for natural gas-fired electricity generation to support a transition to a cleaner electricity sector. These regulations will be developed in consultation with provinces, territories and Indigenous peoples, as well as with a range of stakeholders (e.g. environmental non-governmental organizations, industry) to ensure that relevant expertise and perspectives are considered.

For the Paris Agreement, Canada committed to a 30% reduction in overall greenhouse gas (GHG) emissions by 2030. A reduction in GHG emissions of over 5 megatonnes (Mt) is expected in 2030 from an accelerated coal phase-out. Air pollution reductions would also be achieved.

Background

In 2014, the electricity sector represented 78 Mt of GHG emissions or 11% of Canada's total GHG emissions. Over 80% of Canada's electricity is generated from non-emitting sources. Clean electricity is fundamental to the transition to a low-carbon economy and can play a role in reducing emissions in other sectors, such as transportation and the built environment, and assist in meeting Canada's 2030 climate change targets. Significant steps have already been taken federally and provincially to reduce GHG emissions from the electricity systems and to develop renewable energy resources. Regulatory action would accelerate the phase-out of coal-fired electricity and set performance standards for natural gas generation.

Proposed approach

Environment and Climate Change Canada intends to amend the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations to phase out traditional coal-fired electricity by 2030. Amendments would require traditional coal-fired units to meet an emissions limit of 420 tonnes of carbon dioxide (CO₂) per gigawatt hour of electricity produced (t/GWh) by no later than 2030.

In addition, Environment and Climate Change Canada intends to set regulatory requirements for natural gas-fired electricity generation, including coal boilers converted to run on natural gas:

• Emissions requirement of 420 t/GWh for new and modified large combustion engine units (>100 megawatts [MW]) and new boilers;
• Emissions requirement of 500 t/GWh for new and modified small combustion engine units (≤100 MW); and
• Interim emissions requirement of 550 t/GWh for modified boiler units converted from coal to natural gas, to apply for 15 years or until 2045, whichever comes first, after which time an emissions requirement of 420 t/GWh would apply.

The Government of Canada remains open to entering into equivalency arrangements under the Canadian Environmental Protection Act, 1999 (CEPA) with jurisdictions that have enforceable measures that are equivalent or better in terms of environmental outcomes relative to the federal regulations.

Timing

Environment and Climate Change Canada will undertake consultations and analyses in 2017 on amendments to the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations and regulatory requirements for natural gas-fired electricity generation, and intends to publish proposed regulations in the Canada Gazette, Part I, at the end of 2017 with final regulations to be published at the end of 2018. It is intended that amendments to the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations will come into force in 2026 and regulatory requirements for natural gas-fired electricity generation will come into force in 2020.

Next steps

Consultation will be undertaken with provinces and territories, as well as with a range of stakeholders (e.g. environmental non-governmental organizations, industry) to ensure that relevant expertise and perspectives are considered as part of the development of amendments to the Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations and regulatory requirements for natural gas-fired electricity generation.

A webinar will be held in late December 2016 to commence the engagement process. This will be followed by a series of technical consultations. Environment and Climate Change Canada will also be working with Indigenous peoples.

This Notice of Intent also provides an opportunity for interested parties to submit comments. Interested parties may submit comments on the general approach set out above by mail or email before February 17, 2017.

DEPARTMENT OF THE ENVIRONMENT
DEPARTMENT OF HEALTH

CANADIAN ENVIRONMENTAL PROTECTION ACT, 1999

Notice of intent to develop regulations respecting asbestos

Whereas the Government of Canada has indicated its commitment to move forward with a ban on asbestos in Canada;

Whereas asbestos is a substance listed in Item 6 of Schedule 1 of the Canadian Environmental Protection Act, 1999 (CEPA 1999);

Notice is hereby given that the Department of the Environment and the Department of Health are initiating the development of proposed regulations made under CEPA 1999 that would seek to prohibit all future activities respecting asbestos and asbestos-containing products, including the manufacture, use, sale, offer for sale, import and export. The proposed regulations are intended to be published in the Canada Gazette, Part I, in December 2017.

To inform the development of the proposed regulations, a mandatory survey notice under section 71 of CEPA 1999 will be published in December 2016. This notice will require mandatory data submission by people who manufacture, import, export and use asbestos and asbestos-containing products in Canada.

As part of an open and transparent process, the development of these regulations will include consultations with representatives of provincial and territorial governments, industry, non-governmental organizations, the public and other stakeholders. Input received during these consultations will be considered during the development of the regulations.

As a first step in the consultation process, interested parties may submit comments on the approach set out above by mail or email by January 18, 2017, to the contact provided below. Subsequently, interested parties will also be consulted in the spring of 2017, and additional information will be available on the following web page: http://www.ec.gc.ca/toxiques-toxics/Default.asp?lang=En&n=A183A275-1. Interested parties will have another opportunity to make written comments specific to the regulatory proposal during the mandatory consultation period that will follow the publication of the proposed regulations in December 2017.

ANNEX I

Background

The proposed regulations will be developed in support of the government-wide approach for the management of asbestos in Canada.

Asbestos is the common name for six naturally occurring minerals (chrysotile, amosite, crocidolite, anthophyllite, tremolite and actinolite). Asbestos has been reviewed by the World Health Organization's International Agency for Research on Cancer and has been declared a human carcinogen. The health risks of asbestos are well established; breathing in asbestos fibres can cause cancer and other diseases, such as asbestosis, mesothelioma and lung cancer.

Asbestos is on the List of Toxic Substances in Schedule 1 of CEPA 1999. This listing covers all six types of asbestos (chrysotile, amosite, crociliodite, anthrophyllite, tremolite and actinolite).

Historically, industry, construction and commercial sectors have used, and, in some cases, continue to use, asbestos in products such as cement and plaster, industrial furnaces and heating systems, building insulation, floor and ceiling tiles, house siding, car and truck brake pads, and vehicle transmission components, such as clutches. Statistics Canada data from 2015 indicates that Canada continues to import products containing asbestos, primarily replacement brake pads for vehicles and construction materials such as cement pipes.

Asbestos is currently managed under various federal acts and regulations. For example, the manufacture, importation, advertisement or sale of consumer products made of asbestos and certain high-risk consumer products that are composed of or contain asbestos fibres are prohibited or strictly regulated under the Asbestos Products Regulations, made under the Canada Consumer Product Safety Act. The Asbestos Mines and Mills Release Regulations under CEPA 1999 were made to limit the concentration of asbestos fibres in gases emitted into the ambient air at asbestos mines or mills resulting from crushing, drying, or milling operations. Crocidolite asbestos is specified in Part 2 of the Export Control List in Schedule 3 to CEPA 1999 and its export is controlled through the Export of Substances on the Export Control List Regulations under CEPA 1999.

The proposed regulations under CEPA 1999 would seek to further manage and control asbestos and asbestos-containing products in Canada by prohibiting the manufacture, use, sale, offer for sale, import and export of asbestos and asbestos-containing products. The proposed regulations would prohibit all activities involving asbestos occurring after the coming into force of the regulations, and therefore would not address any activities that occurred prior to the coming into force of the regulations (such as construction materials containing asbestos that already exist within buildings).

Actions in other jurisdictions

With the exception of chrysotile asbestos, all other forms of asbestos are listed under the Rotterdam Convention. The Rotterdam Convention is a global treaty that aims to protect human health and the environment by establishing a “prior informed consent” procedure for listed chemicals. Through this procedure, Parties must not export a substance to another Party that does not consent to the chemicals being imported into their country and must respect conditions imposed by the importing Party.

More than 50 countries, including those of the European Union, Japan, Australia, Argentina, Brazil, Chile, Uruguay and South Korea, have already banned asbestos, with a limited number of exemptions.

In the United States, some products containing asbestos are banned, such as corrugated paper, rollboard, commercial paper, specialty paper, and flooring felt. Some products containing asbestos that are still not banned include cement corrugated sheets, cement flat sheets, clothing, pipeline wrap, roofing felt, vinyl floor tiles, cement shingles, millboard, cement pipes, automatic transmission components, clutch facings, friction materials, disk brake pads, drum brake linings, brake blocks, gaskets, non-roofing coatings, roof coatings. Any new uses of asbestos after 1989 have been banned.

ANNEX

Summary of the draft screening assessment of chloral hydrate

Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of Environment and Climate Change and the Minister of Health have conducted a screening assessment of 1,1-ethanediol, 2,2,2-trichloro-, hereinafter referred to as chloral hydrate. The Chemical Abstracts Service Registry Number (CAS RN) for chloral hydrate is 302-17-0. This substance is among those substances identified as priorities for assessment as it met categorization criteria under subsection 73(1) of CEPA.

Chloral hydrate does not occur naturally in the environment. In Canada, it is primarily found in chlorinated drinking water as a disinfection by-product. It is also an active ingredient in prescription drugs used as sedatives and hypnotics, a medicinal ingredient in natural health products licensed as homeopathic medicines, and an intermediate for industrial metal plating.

The ecological risk of chloral hydrate was characterized using the ecological risk classification of organic substances (ERC). The ERC is a risk-based approach that employs multiple metrics for both hazard (potency) and exposure based on weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles are established based principally on metrics regarding mode of toxic action, chemical reactivity, food web-derived internal toxicity thresholds, bioavailability, and chemical and biological activity. Metrics considered in the exposure profiles include potential emission rate, overall persistence, and long-range transport potential. A risk matrix is then used to assign a low, moderate or high level of potential concern for substances based on their hazard and exposure profiles. Substances with low risk classification outcomes are affirmed using local-scale (i.e. in the area immediately surrounding a potential point-source of discharge) risk scenarios designed to be protective of the environment. The ERC identified chloral hydrate as having low potential to cause ecological harm.

Considering all available lines of evidence presented in this draft screening assessment, there is a low risk of harm to organisms and the broader integrity of the environment from chloral hydrate. It is proposed to conclude that chloral hydrate does not meet the criteria under paragraph 64(a) or (b) of CEPA, as it is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity or that constitute or may constitute a danger to the environment on which life depends.

Drinking water is the primary source of exposure to chloral hydrate for the general population of Canada. Exposure to the general population through its use in the metal plating industry is not expected, as chloral hydrate is consumed in the plating process.

Chloral hydrate was previously assessed by Health Canada, and a drinking water guidance document was published that determined that the amount of chloral hydrate typically found in drinking water is well below the level at which health effects may be observed. A health-based value was derived, with an increased incidence of liver histopathology as the critical health effect.

Based on the information presented in this draft screening assessment, it is proposed to conclude that chloral hydrate does not meet the criteria under paragraph 64(c) of CEPA, as it is not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Proposed conclusion

It is proposed to conclude that chloral hydrate does not meet any of the criteria set out in section 64 of CEPA.

Consideration for follow-up

While exposure of the general population to chloral hydrate is not of concern at current levels, this substance is considered to have a health effect of concern based on its potential carcinogenicity. Therefore, there may be a concern for human health if exposures were to increase. Follow-up activities to track changes in exposure and/or commercial use patterns are under consideration.

Stakeholders are encouraged to provide, during the 60-day public comment period on the draft screening assessment, any information pertaining to the substance that may help inform the choice of follow-up activity. This could include information on new or planned import, manufacture or use of the substance, or information not previously submitted to the ministers.

The draft screening assessment for this substance is available on the Government of Canada's Chemical Substances website (www.chemicalsubstances.gc.ca).

Proposed residential indoor air quality guideline for acetaldehyde

Pursuant to subsection 55(3) of the Canadian Environmental Protection Act, 1999, the Minister of Health hereby gives notice of a proposed residential indoor air quality guideline for acetaldehyde.

The following exposure limits are proposed:

Exposure period	Concentration
	Micrograms per Cubic Metre (µg/m3)	Parts per Billion (ppb)
Short-term (1 hour)	1 420	795
Long-term (24 hours)	280	157

The Government of Canada has previously conducted an evaluation of the human health effects associated with exposure to acetaldehyde with a literature cut-off date of February 1998 (Environment Canada and Health Canada, 2000). This current assessment provides an update on the health effects of acetaldehyde, based on scientific information published since the previous report. As a result of the updated health risk information, and taking into account any comments submitted during the 60-day public comment period, Health Canada and Environment and Climate Change Canada will consider if further action is required (e.g. updating the Priority Substances List assessment report or the Risk Management Strategy).

Any person may, within 60 days after publication of this notice, file with the Minister of Health written comments on the proposed guideline. All written comments are to be made publicly available to all interested parties. All comments, requests for copies of the full science assessment, and information requests must cite the Canada Gazette, Part I, and the date of publication of this notice and be sent to the Water and Air Quality Bureau, Health Canada, 269 Laurier Avenue West, Ottawa, Ontario K1A 0K9, 613-957-1876 (telephone), 613-948-8482 (fax), air@hc-sc.gc.ca (email).

ANNEX

Residential indoor air quality guideline: acetaldehyde

Background

Acetaldehyde is a colourless, flammable liquid with a pungent and irritating odour, is volatile at ambient temperature and pressure, and is found in both indoor and outdoor air. In Environment Canada and Health Canada's 2000 Priority Substance List Assessment Report: Acetaldehyde, it was concluded that acetaldehyde is toxic under the Canadian Environmental Protection Act, 1999 (CEPA) because it may be a genotoxic carcinogen; however, there was considerable uncertainty as to the actual cancer risk. Since the publication of the report, a number of key studies have been published, including those related to the mode of action for acetaldehyde carcinogenesis. Therefore, in order to address the uncertainty in regard to the mode of action of acetaldehyde carcinogenesis, and to more accurately determine the risk to health from levels commonly found in Canadian homes, taking into account recently published scientific data, this substance was given high priority for a full health risk assessment and development of a Residential Indoor Air Quality Guideline (RIAQG) for acetaldehyde.

The present document reviews the epidemiological, toxicological, and exposure research on acetaldehyde, as well as the conclusions from a number of comprehensive reviews from internationally recognized health and environmental organizations. The document places an emphasis on research published since the most recent comprehensive review, and proposes new short- and long-term indoor air exposure limits. This RIAQG for acetaldehyde is intended to provide recommended exposure limits that would minimize risks to human health and support the development of actions to limit acetaldehyde emissions. This document also shows that, when compared to the newly proposed guidelines, levels in Canadian houses do not present a health risk.

Sources and exposure

Acetaldehyde is found ubiquitously throughout the ambient environment. Natural outdoor sources include higher plant respiration processes and emissions from forest fires. Combustion represents a major anthropogenic source of acetaldehyde, through incomplete combustion of organic material and fuels in motor vehicles. Emissions from industrial production, storage, transport, or disposal of products with residual acetaldehyde can also contribute to ambient concentrations. Secondary formation of acetaldehyde can occur through the oxidation of natural and anthropogenic volatile organic compounds (VOCs) present in the atmosphere.

There are numerous sources of acetaldehyde emissions in the indoor environment, often resulting in higher levels compared to outdoors. Incomplete combustion in fireplaces, wood-burning stoves and environmental tobacco smoke, along with certain cooking processes (notably those that use cooking oil) can emit significant quantities of acetaldehyde indoors. Emissions from products for interior finishes, such as vinyl flooring and carpets, and wood-based building materials, such as fibreboard and particleboard, as well as paints, stains, adhesives, caulking and foam sealants, may also contribute to indoor levels of acetaldehyde. An additional source of acetaldehyde indoors is from the infiltration of vehicle exhaust fumes into the home from an attached garage.

Some consumer products may directly contribute to indoor acetaldehyde levels, such as fragranced consumer products (e.g. air fresheners, liquid fabric softeners, and dryer sheets, which may contain acetaldehyde), as well as indirectly via secondary formation of acetaldehyde from indoor reactions of ozone with other organic aerosols. Elevated indoor acetaldehyde levels have been shown to be associated with higher occupant density, likely due to “occupant activities” including, but not limited to, respiration releasing endogenously produced acetaldehyde.

Median acetaldehyde levels from Health Canada exposure studies measured in four cities (Edmonton, Halifax, Regina and Windsor) during winter and summer from 2005 to 2010 ranged from 10.5 to 48.7 µg/m³ (indoors) and from 2.4 to 7.2 µg/m³ (outdoors) [Health Canada 2010a, 2010b, 2012, 2013]. In one study (Windsor), personal exposure measurements were also collected, with a median range of 18.6 to 39.3 µg/m³. In these studies, the ratio of indoor to outdoor acetaldehyde concentrations was in general consistently above 2.5, which is indicative of a predominance of indoor sources of acetaldehyde.

Health effects

The health effects of exposure to acetaldehyde have been examined in toxicological and controlled human exposure studies, with very little epidemiological evidence related to indoor acetaldehyde exposure. In this assessment, the short-term exposure limit is derived from the results of a controlled human exposure study, whereas the long-term exposure limit is based on toxicological data from a study in a rodent model. Supporting evidence is provided by the results of other toxicological and controlled human exposure studies.

Based on the evidence from human and toxicological studies, the effects of short-term and long-term acetaldehyde inhalation are observed at the site of entry. Key health effects include tissue damage and cancer development, mainly in the upper respiratory tract.

Human studies

From the studies with human participants, acute exposure induced eye irritation and potentiated the bronchoconstriction response to methacholine challenge at acetaldehyde concentrations as low as 22 mg/m³, with nose and throat irritation reported at 50–200 ppm (89–357 mg/m³) [Myou et al. 1994b; Silverman, Schulte and First 1946]. At higher concentrations (350–1 000 mg/m³), aerosolized acetaldehyde was shown to directly cause bronchoconstriction in people with asthma (Myou et al. 1993; 1994b; 1994c; 1995; Fujimura et al. 1997; Prieto et al. 2000; 2002a; 2002b), and a bronchoconstrictive effect was induced in people with allergic rhinitis (2 240 mg/m³) [Prieto et al. 2002b]. Epidemiological data on the long-term effects in humans is limited to a single cross-sectional study of school children (Flamant-Hulin et al. 2010) demonstrating a significant association between acetaldehyde exposure (measured in classrooms) and increased pulmonary inflammation for non-asthmatic children, but not for asthmatic children.

Toxicological studies

In laboratory animals, acute acetaldehyde exposure induced irritation and bronchoconstriction responses. For sensory irritation, the lowest concentration that elicited a 50% decrease in respiratory rate was 2 845 ppm (5 080 mg/m³) for a 10-minute exposure in mice (Steinhagen and Barrow 1984), while exposure at ≥ 25 ppm (45 mg/m³) acetaldehyde in rats increased vasodilation in the upper respiratory tract (Stanek et al. 2001).

Long-term inhalation exposure to acetaldehyde in animal studies caused a number of non-neoplastic effects primarily in the upper respiratory tract, specifically inflammation and tissue injury (degeneration, hyperplasia, and metaplasia). In rat studies, long-term acetaldehyde exposure caused adverse effects in the olfactory and respiratory epithelia of the nasal cavity, with lesions noted at exposure concentrations as low as 268 mg/m³, and tissue injury sometimes reported in the larynx, pharynx, and trachea, typically at higher exposure levels (Woutersen et al. 1984; 1986; Saldiva et al. 1985; Appelman et al. 1986; Woutersen and Feron 1987; Cassee et al. 1996b; Cassee, Groten and Feron 1996; Oyama et al. 2007; Dorman et al. 2008; Feron, Kruysse and Woutersen 1982; Woutersen et al. 1984; 1986). In hamster studies, tracheal and laryngeal tissues were more sensitive than the nasal cavity was, although effects were observed at higher concentrations than in the rat studies (Kruysse, Feron and Til 1975; Feron 1979; Feron, Kruysse and Woutersen 1982), indicating a species-related difference. In a small number of animal studies, other adverse effects, namely reduced pulmonary bactericidal activity (Aranyi et al. 1986), increased airway hyperresponsiveness (Kawano et al. 2012), neurological effects (Ortiz, Griffiths and Littleton 1974; Shiohara et al. 1985), and altered gonad weight (Kruysse, Feron and Til 1975), were noted. Growth retardation and mortality were observed at the highest exposure levels (4 464–8 929 mg/m³) [Kruysse, Feron and Til 1975; Feron 1979; Feron, Kruysse and Woutersen 1982].

The International Agency for Research on Cancer (IARC) categorized acetaldehyde as a class 2B carcinogen (possibly carcinogenic to humans) [IARC 1999]. Acetaldehyde has been shown to be genotoxic and mutagenic, inducing DNA damage in the form of DNA adducts, DNA–DNA crosslinks, DNA–protein crosslinks as well as more complex adducts (reviewed in Albertini 2013), and mutagenicity in in vitro test systems (Environment Canada and Health Canada 2000), as well as in an in vivo inhalation study in aldehyde dehydrogenase 2 (ALDH2) knockout mice (Kunugita et al. 2008). Chronic inhalational exposure has caused carcinogenic effects in rats and hamsters, at concentrations that induce tissue changes in the upper respiratory tract, with similar specific-related differences in concentrations consistent with the non-neoplastic effects. In rats, chronic exposure resulted in concentration-dependent increase in adenocarcinoma of the olfactory epithelium and squamous cell carcinoma of the respiratory epithelium, occurring at the lowest exposure level (1 339 mg/m³) [Woutersen et al. 1986]. In hamsters, chronic exposure at ≥2 946 mg/m³ acetaldehyde resulted in a significant increase in tumour incidence of the larynx (Feron 1979; Feron, Kruysse and Woutersen 1982).

Susceptible subpopulations

Studies of short-term exposures in human volunteers provide evidence that asthmatics are a sensitive subgroup to inhaled acetaldehyde (Myou et al. 1993; Prieto et al. 2000; 2002b). An ALDH2 polymorphism (ALDH2-2, the non-functional variant, prevalent in 40% to 50% of the Asian population, which greatly alters the rate of acetaldehyde metabolism following alcohol consumption) may confer additional susceptibility to acetaldehyde exposure. Although an increased severity of formaldehyde-induced effects has been demonstrated in studies using ALDH2 knockout mice (as compared to wild-type mice) [Isse et al. 2005; Oyama et al. 2007; 2010], no significant difference in hyperresponsiveness was observed in human studies following inhaled aerosolized acetaldehyde (Teeguarden et al. 2008).

Mode of action for carcinogenesis

The weight of evidence points to a non-linear (or threshold) mode of action (MOA) for acetaldehyde carcinogenesis. The pattern of genotoxicity and mutagenicity is consistent with a cytotoxic (secondary to a proliferative response), rather than a mutagenic (critical early event), MOA for carcinogenicity. Tumour development is proposed to be related to the occurrence of tissue damage and is dependent on saturation of capacity for acetaldehyde metabolism, enhanced cellular proliferation and mutation in the nasal cavity.

There is evidence that the toxic effects of acetaldehyde may be due, in part, to an overwhelming of the acetaldehyde detoxification capacity at the site of exposure. Evidence indicates that acetaldehyde toxicity is associated with decreased ALDH activity, and is most predominant in ALDH knockout mouse models. In addition, decreased upper respiratory tract uptake of acetaldehyde at elevated concentrations appears to be related to ALDH activity. Following saturation of the metabolic capacity for acetaldehyde, the carcinogenicity of acetaldehyde is proposed to be dependent on the induction of cytotoxicity, leading to increased cell turnover from recurrent tissue damage and repair. While no studies examining the association between acetaldehyde inhalation and cell proliferation in the upper respiratory tract were identified, enhanced cell proliferation of the tongue, epiglottis and forestomach (i.e. tissues related to route of entry) was observed in a rat study following administration in drinking water (Homann et al. 1997). In addition, acetaldehyde has been shown to induce DNA damage in the form of DNA adducts, DNA–DNA crosslinks, DNA–protein crosslinks as well as more complex adducts. These types of damage, under certain conditions including at high exposure concentrations and in association with tissue damage, lead to mutation.

The pattern of key events leading to tumour development resembles that observed for formaldehyde, which is also proposed in the literature to act via a non-linear MOA for carcinogenesis. There is a high degree of similarity in formaldehyde and acetaldehyde carcinogenesis, including similarities in the structure and toxicity of the two compounds, the critical key events including DNA–protein crosslink formation, the development of nasal carcinomas in animals at highly irritating and damaging concentrations, and limited evidence of genotoxicity in vivo.

Residential indoor air quality guideline for acetaldehyde

The determination of a RIAQG is carried out in two stages. First, a reference concentration (RfC) is derived by applying uncertainty factors to the concentrations at which the most sensitive adverse health endpoint was observed. The RfC approach is used for the determination of a guideline to reduce potential health impacts such as those observed in key toxicological, controlled human exposure, and indoor epidemiological studies.

For the short-term exposure RfC, the exposure period is specified; in the present case, one hour. For the long-term exposure RfC, the exposure is considered to occur over months or years, up to a lifetime.

In the second stage, the short- and long-term exposure RfCs are compared with measured exposures in residential indoor air, and evaluated with respect to their technical feasibility. If the RfC is considered attainable where reasonable control measures are followed, the RIAQG is set equal to the RfC. If the RfC is considered unattainable with currently available risk management technology and practices, the RIAQG may be set at a higher concentration. Setting the RIAQG at a higher concentration than the RfC results in a smaller margin of exposure between the RIAQG and the concentration at which effects have been observed in health studies. Nonetheless, a RIAQG derived in this manner does provide a measure of health protection, while remaining an achievable target for improving indoor air quality when evaluating risk management measures.

Short-term residential indoor air quality guideline

For short-term exposure to acetaldehyde, a study investigating bronchoconstriction response in human volunteers identified that the provocative concentration required to produce a 20% fall in forced expiratory volume in one-second (FEV₁) geometric mean for asthmatic subjects was 527 mg/m³ (95% confidence interval [CI]: 142–1 149 mg/m³) acetaldehyde following a two-minute exposure (Prieto et al. 2000). The lower 95% confidence level of 142 mg/m³ was chosen as the point of departure and uncertainty factors (UFs) of 10 to account for the use of a lowest observed adverse effects level (LOAEL) and 10 to account for additional sensitivity in the human population (e.g. more severe asthmatics, children, ALDH polymorphisms) were applied. Thus, the short-term RfC is 1 420 µg/m³. The Health Canada residential indoor air exposure studies provide 24-hour integrated samples of acetaldehyde measurements, which do not represent acute or peak exposure. It is evident from these 24-hour measurements that the short-term reference exposure level is significantly higher than the median range of indoor air concentrations. Therefore, as this exposure limit is achievable in Canadian homes, the proposed short-term RIAQG for acetaldehyde is 1 420 µg/m³.

It is recommended that the short-term exposure limit be compared to a one-hour air sample.

Long-term residential indoor air quality guideline

For chronic exposure, the most sensitive neoplastic endpoint was adenocarcinoma in the nasal cavity of male rats, with the most sensitive non-neoplastic endpoint being degeneration of the olfactory epithelium in rats. As discussed above, a strong body of evidence has also emerged to support the notion that acetaldehyde exerts its carcinogenic effect through a non-linear MOA, with the non-neoplastic effects being precursors to a carcinogenic response. Therefore, derivation of an RfC for the neoplastic effects of acetaldehyde is based on the observation of the non-neoplastic effects. A no observed adverse effect level (NOAEL) of 89 mg/m³ is selected, based on degeneration of the olfactory epithelium in rats (Dorman et al. 2008). Using an upper respiratory tract physiologically based pharmacokinetic model for acetaldehyde inhalation, the human equivalent concentration (HEC) calculated is 120 mg/m³. This value is adjusted for continuous exposure, resulting in an adjusted HEC of 21 mg/m³. UFs of 2.5 to account for toxicodynamic differences between animals and humans, 10 for additional sensitivity in the human population, and 3 for uncertainty in the shape of the lower region of the concentration–response curve were applied, resulting in a total UF of 75. Thus, the long-term RfC is 280 µg/m³. The range of median indoor air acetaldehyde concentrations measured in Canadian homes from the Health Canada residential indoor air exposure studies for a 24-hour averaging period was 10.5 to 48.7 µg/m³, with the 95th percentile ranging from 35.6 to 149.5 µg/m³. This indicates that the concentration of acetaldehyde in Canadian homes would not exceed the RfC of 280 µg/m³. Therefore, the proposed long-term RIAQG for acetaldehyde is 280 µg/m³.

When comparing a measured acetaldehyde concentration with the long-term exposure limit, the sampling time should be at least 24 hours.

Residential maximum exposure limit for acetaldehyde

Exposure period	Concentration		Critical effects
	µg/m3	ppb
Short-term (1 hour)	1 420	795	Increased airway responsiveness in asthmatics
Long-term (24 hours)	280	157	Olfactory epithelial degeneration in the nasal cavity of rats

Levels in a typical Canadian home are likely well below both the short-term and long-term exposure limits and, accordingly, are unlikely to pose a health risk.

Strategies for reducing exposure to acetaldehyde include controlling indoor emissions from combustion appliances and smoking. Control measures include the following:

• Do not smoke inside the home.
• Properly install and maintain combustion appliances used for heating (e.g. gas and oil furnaces, wood stoves, gas water heaters), with venting outside.
• Use a higher fan setting when cooking on a gas stove, ensure that it vents outside, and preferentially use the back burners.
• When using and applying consumer products such as paints, adhesives, coatings and lubricants, inks, nail polish remover, and fragrances in the home, ensure the area is well ventilated and follow all label recommendations. These products should be kept well sealed and/or in non-occupied areas of the home not connected to the ventilation system, where possible.
• Prevent leaks from an attached garage to the house and make sure that there is an appropriate seal between the home and the garage, particularly for any door that connects the two.
• When performing home renovations, including the installation of carpeting or vinyl flooring and painting in the home, the area should be well ventilated and the user should follow all label recommendations.

Use of these strategies will help to reduce exposure to acetaldehyde and other indoor air contaminants, particularly contaminants in combustion gases and consumer products, including other VOCs.

On February 11, 2015, the Hazardous Products Act (HPA) was amended, and the Controlled Products Regulations (CPR) and the Ingredient Disclosure List were repealed and replaced with the new Hazardous Products Regulations (HPR). The revised legislation (HPA/HPR) is referred to as WHMIS 2015 and the former legislation (HPA/CPR) is referred to as WHMIS 1988.

Transitional provisions allow compliance with either WHMIS 1988 or WHMIS 2015 for a specified period of time. All claims for exemption in this publication were filed and evaluated in accordance with the provisions of WHMIS 1988.

There were no written representations from affected parties with respect to any of the claims for exemption and related MSDSs or labels mentioned below.

Each of the claims for exemption listed in the table below was found to be valid except for those for Registry Number (RN) 9674, which was found to be partially valid. The screening officer reached this decision after reviewing the information in support of the claim, having regard exclusively to the criteria found in section 3 of the Hazardous Materials Information Review Regulations.
