1. Labor Code (LC) - 129 chemicals
At a minimum, the list must contain chemicals identified by reference in Labor Code section 6382(b)(1) or (d). Labor Code section 6382(b)(1) incorporates chemicals identified by the World Health Organization’s International Agency for Research on Cancer (IARC) as causing cancer in humans or laboratory animals.
2. State's Qualified Experts (SQE) - 322 chemicals
Either of two independent committees of scientific and health experts can find that a chemical has been clearly shown to cause cancer or birth defects or other reproductive harm. These two committees—the Carcinogen Identification Committee (CIC) and the Developmental and Reproductive Toxicant Identification Committee (DARTIC) — meet at least once each year and are designated as the “State’s Qualified Experts” for evaluation of chemicals under Proposition 65.
3. Authoritative Bodies (AB) - 290 chemicals
The CIC and DARTIC have designated certain organizations as “authoritative bodies.” A chemical will be added to the Proposition 65 list if one of these authoritative bodies formally identifies it as causing cancer or birth defects or other reproductive harm.
The following organizations have been designated as authoritative bodies: the US Environmental Protection Agency, US Food and Drug Administration (US FDA), National Institute for Occupational Safety and Health, the National Toxicology Program of the US Department of Health and Human Services, and IARC.
