Environmental Health - Toxic Substances


Frequently Asked Questions

Should I be concerned about your findings?
The concentrations measured during this study were generally very low. Fourteen of the 95 compounds have some kind of drinking-water guidelines, health advisories, or aquatic-life criteria established. However, they were rarely exceeded. Agencies such as the U.S. Environmental Protection Agency, and the Food and Drug Administration have regulatory programs to protect public and ecosystem health, and processes are in place for licensing and regulation of new compounds that might make their way into the environment. More is yet to be learned about the potential toxicological effects of many of the compounds under investigation. The information provided by this study will be useful to future research and regulatory decision-making.
