ANNEX
Summary of the draft screening assessment of the Naphthalene Sulfonic Acids and Salts Group
Pursuant to section 68 or 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of six of seven substances referred to collectively under the Chemicals Management Plan as the Naphthalene Sulfonic Acids and Salts Group. These six substances were identified as priorities for assessment as they met categorization criteria under subsection 73(1) of CEPA or were considered a priority on the basis of other human health or ecological concerns. Although three substances in this Group did not meet categorization criteria, they were included in this assessment because they were determined to be priorities as a result of the approach for the identification of risk assessment priorities. A seventh substance was initially included in the Group; however, it was determined to be of low concern through other approaches, and the conclusion for this substance is provided in a separate report.footnote 1 Accordingly, this screening assessment addresses the six substances listed in the table below. The six substances addressed in this screening assessment are hereinafter referred to as the Naphthalene Sulfonic Acids and Salts Group (NSAs Group). The Chemical Abstracts Service Registry Numbers (CAS RNsfootnote 2), the Domestic Substances List (DSL) names and the acronyms of these substances are listed in the table below.

All six substances in the NSAs Group are commercially produced and do not occur naturally in the environment. The six substances were included in surveys issued pursuant to section 71 of CEPA. According to information submitted, NaNSA was manufactured in a total quantity between 100 000 kg and 1 000 000 kg, and less than 1 000 kg of CaDNNSA was manufactured in Canada. The remaining substances in the Group were not manufactured in Canada but were imported into Canada in quantities of 1 000 kg to 100 000 kg for each substance. These substances have a variety of uses in fuels, lubricants, oil and natural gas extraction, paints and coatings, rubber materials, and water treatment.
The ecological risk of NaNSA was characterized using the ecological risk classification of organic substances (ERC), which is a risk-based approach that employs multiple metrics for both hazard and exposure, with weighted consideration of multiple lines of evidence for determining risk classification. Based on the outcome of the ERC analysis, NaNSA is considered unlikely to be causing ecological harm.
The other five substances in the NSAs Group were assessed for ecological risk based on a mixture of empirical and analogue hazard data, which informed the fate and effects of these substances. Due to similarities in the chemical structures and effects of these substances, their hazard was considered as a group. Similarly, their ecological exposure was considered as a group due to the assumed potential for interchangeable industrial uses of the substances. Some of these substances may be persistent and bioaccumulative. The exposure scenarios examined in the ecological assessment included aquatic releases from lubricant oil blending, use of metal working fluids, formulation of paints and coatings, formulation of oil and gas products, and industrial use of paints. Exposure to soil via the application of biosolids to land, and exposure in sediment, were also considered. A low risk was identified from these five NSAs at current levels of exposure.
Considering all available lines of evidence presented in this draft screening assessment, there is a low risk of harm to the environment from the six substances in the NSAs Group. It is proposed to conclude that the six substances in the NSAs Group do not meet the criteria under paragraph 64(a) or (b) of CEPA, as they are 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.
With respect to human health, BaDNNSA and CDINSA were evaluated using the approach applied in the Rapid Screening of Substances with Limited General Population Exposure assessment to determine if a substance requires further assessment on the basis of the potential for direct and indirect exposure of the general population. On the basis of this approach, the potential for exposure of the general population to BaDNNSA and CDINSA was considered to be negligible, indicating a low probability of risk to human health. Therefore, BaDNNSA and CDINSA are considered to be a low concern for human health at current levels of exposure.
For the four other substances, Canadians may be exposed to DNNSA, CaDNNSA and DNNDSA mainly through drinking water, while NaNSA is not released to the environment. In addition, DNNSA may be used as an antistatic agent in certain food packaging materials with potential for direct food contact. However, exposure from this food packaging use is expected to be negligible. The general population is not expected to be exposed to NaNSA, DNNSA or DNNDSA from the use of products available to consumers. The use of a general purpose aerosol lubricant containing CaDNNSA may result in intermittent inhalation and dermal exposures to this substance.
NaNSA was not identified as posing a high hazard to human health on the basis of classifications by other national or international agencies for carcinogenicity, genotoxicity, developmental toxicity, or reproductive toxicity. Further investigation into the potential health effects of NaNSA was not pursued as exposure of the Canadian general population to this substance is not expected. The health effects data for DNNSA, CaDNNSA and DNNDSA were limited; therefore, a read-across approach was used to inform the health effects characterization of these substances. On the basis of laboratory studies conducted on structurally related substances, the critical health effects of DNNSA, CaDNNSA, and DNNDSA are considered to be crystal formation in the kidneys and effects on the thyroid. Comparisons of levels of exposure to DNNSA or DNNDSA from environmental media to levels at which health effects occur result in margins that are considered adequate to address uncertainties in the health effects and exposure databases. Similarly, comparisons of levels of exposure to CaDNNSA from environmental media and from the use of a lubricant containing CaDNNSA to levels at which health effects occur result in margins that were considered adequate to address uncertainties in the health effects and exposure databases.
On the basis of the information presented in this draft screening assessment, it is proposed to conclude that the six substances in the NSAs Group do not meet the criteria under paragraph 64(c) of CEPA, as they are 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 therefore proposed to conclude that the six substances in the NSAs Group do not meet any of the criteria set out in section 64 of CEPA.
The draft screening assessment for these substances is available on the Canada.ca (Chemical Substances) website.

ANNEX
Summary of the draft screening assessment of sulfurized isobutylene
Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of 1-propene, 2-methyl-, sulfurized (CAS RN 68511-50-2) hereinafter referred to as sulfurized isobutylene. This substance was identified as a priority for assessment, as it met categorization criteria under subsection 73(1) of CEPA.
Sulfurized isobutylene is a UVCB (which stands for substances of unknown or variable composition, complex reaction products, or biological materials) and does not occur naturally in the environment. In 2011, results from a survey issued pursuant to a CEPA section 71 notice indicated that it was not manufactured in Canada above the reporting threshold of 100 kg and that it was imported in quantities between 10 000 and 100 000 kg. Its primary use in Canada was reported to be as a lubricant and lubricant additive in lubricants and greases.
The ecological risk of sulfurized isobutylene was characterized using the ecological risk classification of organic substances (ERC), which is a risk-based approach that employs multiple metrics for both hazard and exposure, with weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles are 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 used to assign a low, moderate or high level of potential concern for substances on the basis of their hazard and exposure profiles. Based on the outcome of the ERC analysis, sulfurized isobutylene is considered unlikely to be causing ecological harm.
Considering all available lines of evidence presented in this draft screening assessment, there is a low risk of harm to the environment from sulfurized isobutylene. It is proposed to conclude that sulfurized isobutylene 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.
Based on available information, the general population is expected to be exposed to sulfurized isobutylene from the use of products available to consumers (lubricants and greases) and from drinking water.
Based on observations in laboratory studies, the critical effects following dermal exposure to sulfurized isobutylene were decreased body weight gain and hematological effects. On the basis of the effects of a similar substance observed in laboratory studies, the critical health effect identified for chronic oral exposure was decreased pup weight in rats.
Comparison of levels of exposure to the general population with levels associated with critical health effects resulted in margins considered adequate to address uncertainties in the health effects and exposure databases.
On the basis of the information presented in this draft screening assessment, it is proposed to conclude that sulfurized isobutylene 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 therefore proposed to conclude that sulfurized isobutylene does not meet any of the criteria set out in section 64 of CEPA.
The draft screening assessment for this substance is available on the Canada.ca (Chemical Substances) website.

Proposed Guideline for Canadian Drinking Water Quality for Diquat
Pursuant to subsection 55(3) of the Canadian Environmental Protection Act, 1999, the Minister of Health hereby gives notice of a proposed Guideline for Canadian Drinking Water Quality for Diquat. The proposed guideline document is available from July 3, 2020, on the Health Canada consultation web page. Any person may, within 90 days after publication of this notice, file with the Minister of Health written comments on the proposed document. Comments must be sent by email at HC.water-eau.SC@canada.ca, or by regular mail to the Water and Air Quality Bureau, Health Canada, 269 Laurier Avenue West, AL 4903D, Ottawa, Ontario K1A 0K9.

On behalf of the Minister of Health
ANNEX
Proposed guideline
A maximum acceptable concentration (MAC) of 0.05 mg/L (50 µg/L) is proposed for diquat (measured as the cation) in drinking water.
Executive summary
This guideline technical document was prepared in collaboration with the Federal-Provincial-Territorial Committee on Drinking Water and is based on assessments of diquat completed by Health Canada’s Pest Management Regulatory Agency (PMRA) and supporting documents.
Exposure
In Canada, diquat is an herbicide that is deliberately applied to food crops and to water sources for weed control. The general Canadian population is therefore potentially exposed to diquat through food, and to a lesser extent, through drinking water. In 2016 (the most recent year for which data are available), more than 500 000 kg of diquat (as active ingredient) was sold in Canada. Very low levels of diquat have been detected in foods. Data provided by provinces and territories that monitor for diquat in source and drinking water indicate that levels of diquat are below the detection limit.
Health effects
In repeat-dose animal studies, diquat primarily targeted the eyes, causing cataracts, and also affected the kidneys and liver. The proposed MAC of 0.05 mg/L (50 µg/L) is based on cataract formation.
Analytical and treatment considerations
Currently, there is one method available for the analysis of diquat in drinking water. The method detection limit is about one to two orders of magnitude below the proposed MAC.
Treatment methods may remove diquat from drinking water supplies, although studies at all scales (bench, pilot or full) are limited or nonexistent. Granular activated carbon (GAC) adsorption is likely the most effective treatment option and membrane filtration techniques (nanofiltration and reverse osmosis) and oxidation may also be effective. Due to lack of performance studies, it is recommended that pilot- and/or bench-scale testing be conducted prior to full-scale implementation.
In cases where diquat removal is desired at a small system or household level, for example, when the drinking water supply is from a private well, a residential drinking water treatment unit may be an option. Adsorption (activated carbon) and reverse osmosis represent the best potential technologies for diquat removal. When using a residential drinking water treatment unit, it is important to take samples of water entering and leaving the treatment unit and send them to an accredited laboratory for analysis to ensure that adequate diquat removal is occurring.
Application of the guideline
Note: Specific guidance related to the implementation of drinking water guidelines should be obtained from the appropriate drinking water authority in the appropriate jurisdiction.
The proposed guideline is protective against health effects from exposure to diquat in drinking water over a lifetime. Any exceedance of the proposed MAC should be investigated and followed by the appropriate corrective actions if required. For exceedances in source water where there is no treatment in place, an investigation to determine the most appropriate way to reduce exposure to diquat should be conducted. This may include use of an alternate water supply or installation of treatment. Where treatment is already in place and an exceedance occurs, an investigation should be conducted to verify diquat efficacy of treatment and determine if adjustments are needed to lower the treated water concentration below the proposed MAC.
International considerations
Other national and international organizations have drinking water guidelines, standards and/or guidance values. Variations in these values can be attributed to the age of the assessments or to differing policies and approaches, including the choice of key study and the use of different consumption rates, body weights and source allocation factors. The three international values established for diquat are based on cataract formation in rats and differ in their interpretation of this study, and in the selection of body weights and source allocation factors.
The United States Environmental Protection Agency has established a maximum contaminant level (MCL) of 0.02 mg/L, while the Australian National Health and Medical Research Council has established a guideline value of 0.007 mg/L for diquat in drinking water. The World Health Organization has calculated a non-regulatory health-based value of 0.03 mg/L (30 µg/L) for diquat.
The European Union does not have a specific parametric value for individual pesticides. Instead, the EU has a value of 0.1 µg/L for any individual (single) pesticide, and a value of 0.5 µg/L for total pesticides found in drinking water. In establishing these values, the EU did not consider the science related to each pesticide, such as health effects. The values are rather based on a policy decision to keep pesticides out of drinking water.
