The EPA is longer accepting studies that use humans as guinea pigs in chemical tests, such as those for dose-response analyses, which determine how much of a chemical is safe for humans.

Since it is certain that human studies provide more accurate assessments of human toxicity than animal tests, ACSH s Jeff Stier sees this ban as a victory for environmental activists: If you can t use studies of people who are already exposed to normal household products, or of volunteers, the environmental activists, who like to rely on the less relevant animal data, can add a ten-fold safety factor to those animal studies and exaggerate assertions of human toxicity.
