is the U.S. statute, administered through the
EPA. It is intended primarily to identify chemicals
that may present "an unreasonable risk of injury to health or the
environment" and to establish a mechanism to control the manufacture,
distribution, and importation of harmful chemicals in commerce. TSCA
requires companies to conduct health effects tests; provide Pre-Manufacture
Notification (PMN) for substances not listed on the EPA inventory; report
health allegations; and develop and maintain production, use, and exposure
data on listed substances.
