The Developmental and Reproductive Toxicant Identification Committee (DARTIC) of California’s Office of Environmental Health Hazard Assessment (OEHHA) will meet on December 10, 2020, to discuss the prioritization of 22 chemicals or chemical groups, including titanium dioxide nanoparticles. DARTIC will provide OEHHA with advice on the prioritization of these chemicals for listing consideration at future meetings. No listing decisions will be made at the meeting. According to OEHHA’s prioritization document for these chemicals, in the most recent application of the prioritization process, OEHHA applied both a human and an animal data screen to candidate chemicals in its tracking database. OEHHA identified 22 chemicals or chemical groups for DARTIC discussion, advice, and consultation. The prioritization document presents information on the identified chemicals or chemical groups. For each, OEHHA presents an initial, abbreviated appraisal of the scientific information identified through the screening-level literature search and the preliminary toxicological evaluation.
