WASHINGTON (CN) - The Environmental Protection Agency is asking chemical manufacturers and importers to provide screening level hazard and risk characteristics of 15 high production volume chemicals to determine if greater regulation of the use of the chemicals is warranted.
A chemical is determined has having a high production volume if more than 1 million pounds of it are produced in, or imported to, the United States in one year. The 15 chemicals account for 95 percent of total chemical production in the U.S. the agency says.
The tests the agency is requiring include: five tests for physical/chemical properties and biodegradation; ecotoxicity; acute toxicity; genetic toxicity including gene mutations and chromosomal aberrations; repeat dose toxicity; and developmental and reproductive toxicity.
