美国环保署EPA:大宗化学品环境问题挑战

【URL】 http://www.epa.gov/chemrtk/volchall.htm

【简介】
     The U.S. high production volume (HPV) chemicals are those which are manufactured in or imported into the United States in amounts equal to or greater than one million pounds per year. The U.S. HPV chemicals were identified through information collected under the Toxic Substances Control Act (TSCA) Inventory Update Rule (IUR). Organic chemicals that are manufactured in, or imported into, the United States in amounts equal to or exceeding 10,000 pounds per year are subject to reporting under the TSCA IUR. Reporting is required every four years.

The HPV Challenge Program Chemical List consists of all the HPV chemicals reported during the 1990 IUR reporting year. Inorganic chemicals and polymers, except in special circumstances, were not subject to the IUR reporting requirements, although a number were reported in error. The HPV Challenge Program Chemical List contains about 2,800 chemicals.

The 1990 IUR list was selected as the starting point for this program.
