styrene environmental impact

Information about releases of styrene from industrial sources and data on concentrations of styrene in air from across Canada were obtained from Canadian databases. 1997. This report examines this new information about the entry, exposure and effects of styrene in the Canadian environment in order to determine if the substance is likely to have a harmful effect on aquatic organisms and wildlife. Total on-site environmental releases of styrene reported to the National Pollutant Release Inventory amounted to 808 000 tonnes in 1996, with most, 729 000 tonnes, released into air (NPRI, 1999). Contributors include more than 10,000 highly qualified scientists and 46 Nobel Prize winners. This public health statement tells you about styrene and the effects of exposure to it. The fathead minnow (Pimephales promelas) was somewhat less sensitive, with a 96-hour LC50 of 10 000 µg/L (Machado, 1995). Styrene -- Toxicity to the freshwater green alga, Selenastrum capricornutum. Beliles, R.P., J.H. See also: Personal chemical exposure informatics; Tools to assess community-based cumulative risk and exposures, The properties that make polystyrene foam a good insulator—its 95 percent air content by volume and its stability to breakdown—also account for its problems for the environment. 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.

Appendix A presents the molecular structures of these substances. Available information was insufficient to conclude whether styrene constituted a danger to the environment under Paragraph 11(a) of CEPA.
