Draft Toxicological Profiles on Silica, Antimony Published by ATSDR

Published June 14, 2017

Draft toxicological profiles for antimony, molybdenum, silica, and 2,4-Dichlorophenoxyacetic acid (2,4-D) are now available for review and public comment from the Agency for Toxic Substances and Disease Registry (ATSDR). ATSDR’s toxicological profiles are intended to characterize the information on toxicologic and adverse health effects for hazardous substances. The peer-reviewed profiles identify and review key literature related to substances’ toxicologic properties. The agency seeks public comments and additional information or reports on studies about the health effects of these for substances. After the comment period closes on Sept. 11, 2017, ATSDR will review comments and consider whether to incorporate them into the final toxicological profiles.

The four new draft toxicological profiles are available on ATSDR’s website:

ATSDR, which is within the Department of Health and Human Services, is directed by congressional mandate to perform specific functions concerning the effect on public health of hazardous substances in the environment.
