The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) aims to specify several substances that as determined by the state to prompt cancer under Proposition 65.

This action is being proposed by the “Labor Code” listing mechanism. OEHHA has finalized these substances that meet their criteria for listing by this mechanism.

The substances are:

  1. Anthracene (CAS No: 120-12-7)
  2. 2bromopropane (CAS No: 45-26-3)
  3. Dimethyl hydrogen phosphite (CAS No: 868-85-9)

Background on the listing by the Labor Code mechanism: Health and Safety Code section 25249.8(a) includes California Labor Code section 6382(b)(1) into Proposition 65. According to Proposition 65, certain chemicals identified by the International Agency for Research on Cancer (IARC) had to be included in the list of substances suspected of causing cancer. The IARC categorized multiple substances as carcinogenic for humans or animals in Labor Code section 6382(b)(1). In Title 27, California Code of Regulations (CCR), section 25904 of the CCR, the OEHHA has enacted regulations about these listings. The OEHHA assesses the probability that a chemical listing is necessary, as the leading agency for Proposition 65 implementation.
