This is accentuated if people reheat the food while still in the container. NPRI (National Pollutant Release Inventory). Briefing by: Government of Canada. Styrene -- Toxicity to the freshwater green alga, Selenastrum capricornutum. Alexander, M. 1990. 9.5 mm Hg @ 30°C  The review of the existing information shows that there is no indication of concern for plants exposed to styrene. Exposures to styrene are addressed in specific OSHA standards for general industry and construction. If these quotients are less than one, it can be concluded that the substance poses no significant risk to the environment, and the risk assessment is completed. The U.S. Food and Drug Administration (FDA) considers polystyrene safe, as long as it contains less than one percent styrene. Global One-Stop Solution for Excess Lab and IT Asset Decommissioning, Data Destruction and Asset Remarketing. 1992b. Recently, questions about the environmental impact of emissions from steam-cured cured-in-place pipe (CIPP) projects have been raised by researchers. Inniss and D.A. Health effects from exposure to styrene may involve the central nervous system and include complaints of headache, fatigue, dizziness, confusion, drowsiness, malaise, difficulty in concentrating, and a feeling of intoxication.. Standards. Although there is evidence that styrene causes cancer in animals, it has not yet been proven to cause cancer in humans. Despite some limitations in the data relating to the environmental effects and exposure of styrene, data available at this time are considered adequate for reaching a conclusion on the environmental risk of styrene in Canada. Priority Substances List assessment report. 95-6-5945). Board Can. Toluene (unedited version). The SIRC Review, April 1990. Environment Canada, Ottawa, Ontario. The regional and country breakdowns section gives an analysis of the market in each geography and the size of the market by region and by country. It usually contains an inhibitor such as tert-butylcatechol. Perry and W.W. Heck. University of Cornell Material Safety Data Sheets (accessed, May, 1999), US EPA Chemical Summaries (accessed, May, 1999), US National Toxicology Program (accessed, May, 1999), USEPA Integrated risk Information System (accessed, May, 1999). Stack and S. Makris. In 2019, SIRC completed and published a comprehensive risk assessment to update the findings of a 2002 Harvard risk assessment. 26 pp. For each endpoint, a conservative Estimated Exposure Value (EEV) is selected and an Estimated No-Effects Value (ENEV) is determined  by dividing a Critical Toxicity Value (CTV) by an application factor. Environmental Protection Agency (EPA), Integrated Risk Information System (IRIS). No information was identified pertaining to styrene, benzaldehyde or benzoic acid. Bishop (eds. You may already have access to this content. The ENEV for terrestrial plants was based on the toxicity of aniline. Environment Canada. Therefore, styrene concentrations in water in Canada are unlikely to cause adverse effects on populations of aquatic organisms. Physical, chemical, toxicological and biological properties of benzene, toluene, xylenes and p-chlorophenyl methyl sulfide, sulfoxide and sulfone. Assuming a bioconcentration factor of 64, biota living in surface waters having a concentration of 1.7 µg/L would have a whole-body concentration of 109 ug/kg. This study was also used by the Canadian Council of Ministers of the Environment to set an interim Canadian water quality guideline of 72 µg/L for the protection of aquatic life (CCME, 1999). Those that are recycled are remanufactured into things like cafeteria trays or packing filler. Submitted to Styrene Information and Research Center, Washington, D.C., by Springborn  Laboratories, Inc., Wareham, Massachusetts, September 14, 1995. Lists styrene as a Hazardous Air Pollutant (HAP) under the National Emissions Standard Hazardous Air Pollutants section of its Clean Air Act. Information was lacking about the potential effects of styrene on aquatic organisms, on terrestrial vegetation through atmospheric exposure, and on wildlife through media other than air. Since 1994, additional toxicity tests have been carried out on aquatic organisms. Total on-site releases amounted to 731 000 tonnes in 1995 (NPRI, 1999). For the general population, adverse health effects are unlikely to occur from exposure to styrene via consumer products or the environment. 1984. Styrene. Submitted to Styrene Information and Research Center, Washington, D.C., by Springborn Laboratories, Inc., Wareham, Massachusetts, September 14, 1995. It is flammable. This value was used by Health Canada to develop a tolerable daily intake for humans (Government of Canada, 1993a). No comments were received. Formaldehyde was included on the second CEPA Priority Substances List (PSL2) and was considered not to be “toxic” as defined in Paragraph 64(a) of the Canadian Environmental Protection Act, 1999 (CEPA 1999). Post-processed polystyrene is perhaps best recognized as the material used in disposable food and beverage containers and packing peanuts. Comparison of a luminescent bacterial test with other bioassays for determining toxicity of pure compounds and complex effluents. There was also insufficient information to determine if styrene constituted a danger to terrestrial vegetation through atmospheric exposure. Priority Substances List assessment report. Dividing this CTV by a factor of 100 (to account for the uncertainty associated with using aniline  toxicity as a surrogate for styrene toxicity, extrapolation from laboratory to field conditions, and interspecies and intraspecies variations in sensitivity) gives an ENEV of 4000 µg/m3. Canadian Environmental Protection Act. The National Pollutant Inventory (NPI) holds data for all sources of Styrene (ethenylbenzene) in Australia. There are, however, some terrestrial plant data on substances  which are close chemical analogues of styrene, which were examined on a case-by-case basis and deemed to be acceptable. Phytotoxicity of hydrocarbons. Slooff, W. and P.J. Styrene Monomer is non-persistent in water, with a half-life of less than 2 days. J. Chem. Styrofoam has become such an accepted everyday product that people often don’t stop to realize that it is made from polystyrene. Vapour pressure: 4.3 mm Hg @ 15°C  © 2004 - 2020 openPR. When Styrofoam containers are used for food, chemicals can leach into the food, affecting human health and the reproductive systems. Information was found pertaining to formaldehyde. https://doi.org/10.1036/1097-8542.BR0807141, Data-mining and informatics approaches for environmental contaminants, Tools to assess community-based cumulative risk and exposures, Canada.com: Now and forever: The Styrofoam dilemma, U.S. Environmental Protection Agency: Styrene, U.S. Food and Drug Administration: CFR - Code of Federal Regulations Title 21, U.S. Food and Drug Administration: Safety of Polystyrene Foodservice Packaging, Additional credits and copyright information. For a hyperconservative risk characterization for terrestrial plants, the EEV is 43.6 µg/m3, the highest 24-hour average concentration of styrene reported in the Canadian atmosphere from 1994 to 1998, inclusive. Environmental health concerns start with the elements used to make Styrofoam. Therefore, no further consideration will be given to this substance in the assessment of possible environmental effects of styrene.

Styrene appeared on the first Priority Substances List (PSL1) of the Canadian Environmental Protection Act (CEPA), which was published in the Canada Gazette, Part I, on February 11, 1989. Bonner and Meresz (1981) reported whole-body concentrations of styrene ranging up to 100 µg/kg in fish from the St. Clair River. A draft follow-up report was made available for a 60-day public comment period (between September 28, 2002 and November 27, 2002). Canadian Chemical Producers’ Association. The CTV is 12 000 µg/kg-bw per day, the lowest NOAEL in a three-generation oral exposure study using rats, based on reproductive effects. Low levels of styrene occur naturally in a variety of foods, such as fruits, vegetables, nuts, beverages, and meats. Another reason that Styrofoam is harmful for the environment is that it is made with petroleum, which is a non-sustainable resource. Organic Trace Contaminants Section, Laboratory Services Branch, Ontario Ministry of the Environment. Government of Canada. Recently, a company called Ecovative Design has created a line of products product made from fungi that are Styrofoam-like and aspire to be a more environmentally friendly replacement. ), Aquatic toxicology and hazard assessment: Fifth conference.
