2.4.1 lf yes, reference to the relevant documentation, which describes the hazard or risk evaluation The Canadian Environmental Protection Act, lggg (cEPA lggg) requires the federal Ministers of Health and the Environment to conduct screening assessments to determine, in an expeditious manner, whether a substance poses a risk to human health or the environment. On the basis of a screening assessment, the Ministers can propose to take no further action in respect of the substance, to add the substance to the Priority Substances List for a more in- depth assessment or to recommend that the substance be added to the List of Toxic Substances in Schedule 1 of the Act.

This assessment was undertaken on the basis that some of these compounds were identif ied as part of a Domestic Substances List (DSL) pilot for screening as they met the criteria for persistence, bioaccumulation and/or inherent toxicity, pursuant to Paragraph 73(1)(b) of cEPA 1999 and in response to a request to the Minister of the Environment to add these compounds to the priority Substance List (PSL) for assessment of ecological and human health.

TNo of the hazard or risk evaluation related to the environment An ecological screening assessment was undertaken on perf luorooctane sulfonate (PFOS), its salts and its precursors containing the perf luorooctylsulfonyl (CBFl7S02, CsF17503, or CsF17SO2N ) moiety.

PFOS is resistant to hydrolysis, photolysis, microbial degradation, and metabolism by vertebrates. PFOS has been detected in f ish, in wildlife worldwide and in the northern hemisphere. This includes Canadian wildlife located far from known sources or manufacturing facilities indicating that PFOS and/or its precursors may undergo long-range transport. Maximum concentrations in liver of biota in remote areãs of tñe Canadian Arctic include: mink (20 Ug.kg'1),. common loon (26 pg.kg'1), ringed seal (37 Ug.kg'1), brook trout (50 Ug.fg't), Arctic f ox (1400 ¡rg.kg'') and polar bear (>4000 Ug.kg''). Unlike many other persistent organic , certain perf luorinated substances, such as PFOS, are present as ions in environmental media and partition preferentially to proteins in liver and blood rather than to lipids. Therefore, the bioaccumulation potential of PFOS may not be related to the typical mechanisms associated with bioaccumulation in lipid-rich tissues. Discretion is required when applying numeric criteria for bioaccumulation such as those outlined in the Government of Canada's Toxic Substances Management Policy (TSMP) and in the Persistence and Bioaccumulation Regulations under CEPA 1999 when determining whether substances such as PFOS are bioaccumulative. These numeric criteria were derived f rom bioaccumulation data for aquatic species and for substances which preferentially partition to lipids.

Environment Canada. June. 2006.

effect of the final action The prohibition on manufacture, use, sale, offer for sale, or import of PFOS and its precursors will work towards the objective of virtual elimination of the substance. Therefore this regulatory action will also result in a reduction of risk for Canada's environment.

2.5 Other relevant information regarding the final regulatory action

2.5.1 Estimated quantity of the chemical produced, imported, exported and used Quantity per year (MT) Year produced 0 2006 imported 6 2006 exported 0 2006 used 6 2006 2.5.2 lndication, to the extent possible, of the likely relevance of the final regulatory action to other states and regions PFOS production has been identified in the United States, Australia, Norway, Italy, Japan, Belgium, Germany and Asia. A number of countries and organizations (including United States, Australia, European Union, Norway, Stockholm Convention on Persistent Organic Pollutants and Protocol to the 197g Convention on Long-Range Transboundary Air ) have either put in place or are proposing management measures to control the manufacture, import, use and releases of PFOS and manufactured products containing PFOS. Therefore the countries aforementioned and many others would not be affected by these Regulations. PFOS has been identified as a Persistent Organic (POP) under the Stockholm Convention. As a result of past releases to the environment due especially to human activities, PoPs are now widely distributed over large regions (including those where POPs have never been used) and, in some cases, they are found around the globe. POPs can be found in people and animals living in regions such as the Arctic, thousands of kilometres from any maior POPs source.

2.5.3 Other relevant information that may cover:

2.5.3.1 Assessment of socio-economic effects of the final regulatory action The costs associated with prohibiting AFFFs relate to the safe disposal of existing stocks, as well as the ¡ncremental costs of replacing the stock with alternatives. The costs associated with metal plating relate to the replacement of the stock with alternatives or the conversion to other control technologies. Costs incurred by the federal government rèlate to enforcement and compliance promotion activities.

The benefits of prohibiting PFOS, its salts and its precursors include protection f rom PFOS exposure of wildlife and ecosystems, including those in remote areas such as the Canadian Arctic, as a result of the reduction in the use of PFOS and protection of water supply sources through the avoidance of contamination as a result of handling, release and use of PFOS. Costs associated with tapping alternate water sources are thus avoided.

More information on the costs and benefits are outlined in the Regulatory lmpact Analysis Statement published with the Requlations.

2.5.3.2 lnformation on alternatives and their relative risks e.g. lPM, chemical and non-chemical alternatives Alternative for PFOS aqueous film forming foam (AFFF): PFOS-free AFFF. Alternatives for f ume suppressants in metal plating industries: non-PFOS-based fume suppressants; other control technologies such as composite mesh pads or closed covers.

9.2 Further information on the properties of the chemical 3.2.1 Description of physico-chemical properties of the chemical The PFOS anion has the molecular formula CeFrzSOg-. The structural formula is CF3(CF2)7SOs-. While PFOS can exist in anionic, acid and salt forms, the PFOS anion is the most common form at pH values in the environment and in the human body.

PFOS and its precursors all belong to the larger class of fluorochemicals referred to as perf luorinated alkyl (PFA) compounds. Perfluorinated chemicals such as PFOS contain carbons that are completely saturated by fluorine. lt is the strength of the C-F bonds that contributes to the extreme stability and physical-chemical properties of these perf luorochemicals.

The precursors have the potential to degrade or metabolize to PFOS. Once PFOS is released to the environment, it is not known to undergo any f urther chemical, microbial or photolytic degradation and is, therefore, persistent. As well as being commercially produced. PFOS is the f inal degradation product from PFOS-derived fluorochemicals. Key physical/chemical properties of PFOS and some precursors that are useful in predicting environmental fate are listed in Table 1 (attached). Ref erence Canadian Environmental Protection Act, 1999 (CEPA 1999): Ecological Screening Assessment Report on Perfluorooctane Sulfonate, lts Salts and lts Precursors that Contain the CeFrzSOz or CBFITSOg or C6F17SO2N Moiety. Environment Canada. June,2006.

3.2.2 Description of toxicological properties of the chemical Although the identified data for some of the substances were variable and limited, the available information indicates that toxicological effects of these precursors of PFOS are similar to those of PFOS itself (described below and in Table 2, attached). Moreover, based upon the data identif ied, health-related effects associated with exposure to these substances would appear to be somewhat less severe and/or are observed at higher exposures (doses) than those associated with exposure to PFOS itself .

The toxicity of PFOS has been studied in a variety of aquatic and terrestrial species, including aquatic plants, invertebrates and vertebrates and terrestrial invertebrates, birds and mammals. Effects in laboratory mammals include: histopathological effects, increased tumor incidence, hepatocellular adenomas, hepatocellular hypertrophy, increased liver, kidney, brain and testes weight, reduced body weight, change in estrous cycling, changes in levels of neurotransmitters, decreased serum cholesterol, decreased bilirubin, and decreased triiodothynine. ln mammalian reproduction studies, effects include: decreased body weight of dams, reduced gestation time, delivery time and live size, transfer of PFOS to fetus and neonate via placenta and ingestion of maternal milk, and reduced survival, body weight gain and development of lactation in offspring of exposed females. Previous studies have shown that perfluorinated compounds are peroxisome proliferators and tumor promoters and may inhibit gap junction intercellular communication at environmentally relevant concentrations.

Environment Canada. June.2006.

3.2.3 Description of ecotoxicological properties of the chemical Estimated steady state PFOS bioconcentration factors (BCF) of 1100 (carcass), 5400 (liver) and 4300 (blood) have been reported for juvenile rainbow trout. The corresponding 12-day accumulation ratios were 690 (carcass),3100 (blood), and 2900 (liver) in juvenile rainbow trout. ln fish livers collected from 23 different species in Japan, bioaccumulation factors (BAFs) were calculated to range from 274 - 41 600. Following an accidental release of f ire f ighting foam, BAFs were calculated in the range of 6300-125 000. Estimated BCFs for the precursors n- ETFOSEA and n-MeFOSEA were 5543 and 26 000, respectively. Species differences for the elimination half-life of PFOS in biota have been determined to vary significantly: 15 days (fish); 100 days (rats),200 days (monkeys) and years (humans). Elimination through the gills is an important route for fish which is not available to birds, terrestrial mammals (e.9., mink, polar bear, Arctic foxes) and marine mammals (e.9., seals and whales). There are three studies suggesting that PFOS biomagnif ies in the Great Lakes and Arctic food webs. For the water-algae- zebra mussel-round goby-smallmouth bass-bald eagle or mink f ood chain, a biomagnification factor (BMF) of 10 to 20 was calculated in mink or bald eagles. A benthic invertebrate/pelagic invertebrate-three forage f ish -top predator f ish food chain resulted in a multi-trophic level BMF of 5.88. lt was suggested that PFOS biomagnif ies through the Arctic marine food web. The trophic level BMFs for PFOS included walrus-clam (a.6); narwhal-cod (7.2); beluga-cod (8.4); beluga-redf ish (a.0); black-legged kittiwake-cod (5.1); glaucous gull-cod (9.0); and cod- zooplankton (0.4). Whole body aquatic BCFs or BAFs are below 5000. However, the weight of evidence f rom both laboratory and field-based BCFs and BAFs in conjunction with the field-based BMFs (avian and aquatic) indicates that PFOS is a bioaccum ulative substance.

Based on available toxicity tests, estimated no effect levels were determined for fish, birds (liver), birds (serum), and wildlife (0.491pg.L't, 0.609 ¡rg.g'1, 0.873 pg.mL-1 and 0.408 Ug.g-1, respectively). The resulting risk quotients for fish, a range of bird species (liver and serum), and wildlife were 0.25, 0.002 to 2.92,0.431o 2.54 and 9.2, respectively. Therefore, current levels show some wildlife oroanisms bear. bird species) could be near or at effect levels and I could be harmed bv current exposures to PFOS.

Category or categories where the final regulatory action has been taken

All use or uses of the chemical in your country prior to the final regulatory action

The major use of PFOS and PFOS related substances in consumer applications was to provide grease, oil and water resistance to materials such as carpets, leatherlapparel, textileslupholstery, paper and packaging, coatings, and in industrial and household cleaning products. These uses have largely been abandoned following the decision of the main global producer 3M to phase out manufacture and use of PFOS consumer applications.

Ongoing industriallprofessional usage of PFOS in smaller volume is continuing and has been confirmed in the following sectors in the EU (current demand, 2004): / - Metal (chromium) plating(8600-10 000 kdlyear) I Fire fighting foams (estimated quantity held in stock, 122 tonnes) I - I 1 - Photographic industry (approximately 850 kglyear) I Semiconductor industry (436 kglyear) I - I - Aviation industry (hydraulic fluids, approximately 730 kglyear)

Final regulatory action has been taken for the category Industrial

Use or uses prohibited by the final regulatory action Firstly, PFOS may not be placed on the market or used as a substance or constituent of preparations in a concentration equal to or higher than 0.005% by weight.

Secondly, PFOS may not be placed on the market in semi-finished products or articles, or parts thereof, if the concentration of PFOS is equal to or higher than 0.1% by weight calculated with reference to the mass of structurally or microstructurally distinct parts that contain PFOS or, for textiles or other coated materials, if the amount of PFOS is equal to or higher than 1 vglm2 of the coated material.

These restrictions shall not apply to products that were in use in the European Community before 27 June 2008.

2.4 Was the final regulatory action based on a risk Yes or hazard evaluation? No (If no, you may also complete section 2.5.3.3)

If yes, reference to the relevant documentation, which describes the hazard or risk evaluation

An OECD hazard assessment has been carried out on the basis of the information available by July 2002. The Environment Agency for England and Wales has issued in 2004 an environmental risk evaluation report on PFOS based on the requirements of Regulation No793193 of 27 March 1993 on the evaluation and control of the risks of existing substances. In addition to this report, another report outlining a risk reduction strategy for, PFOS was established by the Department for Environment, Food and Rural Affairs and the Environment Agency for England and Wales. However, there is no EU Risk Assessment Report but the EU "Scientific Committee on Health and Environmental Risks" (SCHER) adopted an opinion on the report outlining a risk reduction strategy forPFOS in 2005.

NO If yes, give summary of the hazard or risk evaluation related to human health, including the health of consumers and workers

Considering the oral assimilation in fish and mammals and the low elimination rate, the SCHER concluded that PFOS poses similar environmental concerns for bioaccumulation to substances which are very bioaccumulative. The toxicity associated with oral route exposure is confirmed as well as its high persistency. Therefore a scientifically based

Form for notification of final regulatory action to ban or severely restrict a chemical Page assessment of persistence, bioaccumulation and toxicity indicates that PFOS fulfils the criteria for very Persistent, very Bioaccumulative and Toxic substances. To be considered as a Persistent Organic Pollutant under the Stockholm Convention, a substance has to be persistent, bioaccumulative, have a potential for long range environmental transport and have the potential to give adverse effects. PFOS fulfils the criteria for all these properties given in Annex D of the Stockholm Convention. The OECD Hazard Assessment also concluded that PFOS is persistent, bioaccumulative and toxic in mammals. PFOS has been detected in the serum of occupational and general populations. There is a statistically significant association between PFOS exposure and bladder cancer and there appears to be an increased risk of episodes of neoplasm of the male reproductive system, the overall category of cancers and benign growths, and neoplasms of the gastrointestinal tract. . . The SCHER considered that the on-going critical uses in the aviation industry, the semiconductor industry and the photographic industry do not pose a relevant risk provided that releases into the environment and workplace exposure are minimised, while for fire-fighting foams, the risks of substitutes should be assessed before reaching a final I decision. It also considered that the use of PFOS in the plating industry shall also be I minimised by applying the best available techniques.

Expected effect of the final regulatory action The severe restriction is intended to cover the major part of the exposure risks, while the other minor uses exempted do not seem to pose a risk. Although PFOS is persistent, it is considered that, as long as re-occurrence of former major uses is not allowed, the concentrations of PFOS in the environment may eventually diminish.

3.2.2 Description of toxicological properties of the chemical Absorption, Distribution, Excretion and Metabolism in Mammals:

PFOS is reported to be well absorbed following oral administration. Following oral administration of radiolabelled PFOS to rats, approximately 95% of the total radioactivity was absorbed after 24 hours. Approximately 86% of the radioactivity was found in the carcass after 24-48 hours. There is no evidence of selective retention in red blood cells. Urinary excretion is reported to be the primary route of excretion in rats; 89 days after administration of a single intravenous dose of radiolabelled PFOS, 30.2 t 1.5% of the total radiolabel was recovered in urine. Mean cumulative faecal excretion was 12.6 + 1.2%. The half-life of elimination of PFOS from the plasma of male rats is reported to be 7.5 days. There is evidence of enterohepatic recirculation of PFOS. In two separate occupational exposure studies in humans, serum PFOS half-lives of approximately 4 years and 8.67 years have been calculated.

Irritation and Sensitisation: PFOS is reported to be non-irritating to the skin of rabbits. In an eye irritation study, rabbits were observed 1, 24, 48 and 72 hours after treatment with PFOS. Maximum irritation was reported after 1 and 24 hours, however, the severity of irritation was not reported. 1 Subchronic Toxicity: Rat (diet. 90 days): LOAEL = 30 mglkg diet (approximately 1.5 mglkg bwlday) (decreased bodyweight and food consumption, increased absolute and relative liver weight (females)) / Monkey (gavage, 90 days): LOAEL = 10 mglkg bwlday (death of all animals) Monkey (gavage, 90 days): LOAEL = 0.5 mglkg bwlday (occasional gastrointestinal tract toxicity, occasional decreased activity) Monkey (oral capsule, 6 months): NOAEL = 0.03 mglkg bwlday (alterations. in lipoprotein cholesterol levels (both sexes) and triiodothyronine levels (females))

I Chronic Toxicity: Rat (diet, 2 years, male): NOAEL = 0.5 mglkg diet (approximately 0.025 mglkg bwlday) (hepatotoxicity) Rat (diet, 2 years, female): NOAEL = 2 mglkg diet (approximately 0.1 mglkg bwlday) (hepatotoxicity)

I Genotoxicity: Negative results have been reported in in vitro reverse mutation assays in Salmonella typhimurium and Escherichia coli, with and without metabolic activation. Negative results were reported in an unscheduled DNA synthesis assay conducted in rat hepatocytes, and in a chromosomal aberration assay conducted in human lymphocytes, with and without metabolic activation. Negative results have been reported in vivo in mice bone marrow micronucleus assays. Negative results have also been reported for T-2247 CoC (50% by weight solution of diethanolammonium salt of PFOS) in in vitro assays with Salmonella typhmurium and Saccharomyces cerevisiae.

Carcinogenicity: Rat: lncidences of hepatocellular adenomas, thyroid follicular cell adenomas, and combined thyroid follicular cell adenomas and carcinomas were increased in both sexes. lncidences of combined hepatocellular adenomas and carcinomas, mammary fibroadenomaladenomas, and combined mammary fibroadenomaladenomas and carcinomas were increased in females.

3.2.3 Description of ecotoxicological properties of the chemical 1 Persistence properties of PFOS I PFOS is persistent in the environment. It does not hydrolyse, photolyse or volatilise from the aquatic environment. PFOS does not undergo biodegradation; no significant biodegradation of PFOS was observed over 28 days, either as net oxygen loss, loss of total organic carbon or loss of primary compound identity. In the following tests, no evidence of biodegradation was observed: I . Activated sludge I Acclimated activated sludge (including added soil and sediment materials) I in both aerobic and closed vial exposures 1 Aerobic soil and sediment cultures I I Anaerobic sludge from sludge digester I 1 Pure microbial cultures I The conclusion drawn is that PFOS meets the P, persistent and vP, very persistent criteria.

Bioaccumulative properties of PFOS There are limited studies available on the bioaccumulation of PFOS. In a flow- through study on bluegill sunfish (Lepomis macrochirus), the bioconcentration factor (BCF) for edible tissue, non-edible tissue and whole fish were calculated from the rates of uptake and depuration because steady state had not been reached after 56 days of exposure. The BCF values obtained were 1124 (edible), 4103 (non-edible) and 2796 (whole fish). The exposure concentration was 0.086 mgll.

Form for notification of final regulatoly action to ban orseverely restrict a chemical Page 1. A flow-through study on carp (Cyprinus carpio), resulted in lower BCF values of 720 at 20 pgll exposure and 200-1500 at 2 pgll.

Higher BCF values of 6300-125000 have ben reported for in situ measurements at the scene of a spill of firefighting foam, but these were considered to be due to the uptake of derivatives which were then metabolised to PFOS, hence the values were overestimated.

In summary, BCF values up to 2800 have been measured in laboratory studies, and this meets the B = bioaccumulative criterion. The occurrence of PFOS in a range of biota supports this conclusion. PFOS has been found in a range of higher organisms in Europe, including seals, dolphins, whales, cormorants, eagles, swordfish, tuna and salmon. The Global Biophase Monitoring Programme found PFOS in liver, blood and other tissues of animals, especially in fish-eating animals.
