What is the Process for Evaluating New Chemicals Under TSCA?
Before a new chemical can be manufactured or imported, the manufacturer must submit a Premanufacture Notice (PMN) to the EPA. The notice contains information on the chemical's identity, production volume, intended uses, and potential health and environmental effects. Toxicologists play a vital role in evaluating these data to assess potential risks. After the review, the EPA can either approve the chemical, require additional testing, or impose restrictions. This ensures that only chemicals that do not pose significant risks are allowed to enter the market.
