July 12 And 13, 2011 Meeting of the Developmental and Reproductive Toxicant Identification Committee (DART IC)

The Developmental and Reproductive Toxicant Identification Committee of OEHHA’s1 Science Advisory Board identifies chemicals for addition to the list of chemicals known to the State to cause reproductive toxicity (Health and Safety Code section 25249.8).  The Committee serves as the “State’s Qualified Experts” for determining whether a chemical has been clearly shown, through scientifically valid testing according to generally accepted principles, to cause reproductive toxicity.

A public meeting of this committee will be held on Tuesday and Wednesday, July 12 and 13, 2011.  The meeting will be available via webcast.  On the day of the meeting, the link to the webcast will be posted on the OEHHA web site.  If you have special accommodation or language needs, please contact the Proposition 65 Office at (916) 445-6900.  TTY/TDD/Speech-to-Speech users may dial 7‑1‑1 for the California Relay Service.

Meeting Synopsis of the Developmental and Reproductive Toxicant Identification Committee Meeting Held on July 12 and 13, 2011

The California Environmental Protection Agency’s (Cal/EPA), Office of Environmental Health Hazard Assessment (OEHHA) convened a meeting of the Proposition 65 Developmental and Reproductive Toxicant Identification Committee (DARTIC) on July 12 and 13, 2011. The meeting was held at the Cal/EPA Headquarters Building in Sacramento, California. 

The Committee:

  • Considered the listing of sulfur dioxide as known to the state cause reproductive toxicity.
  • Received an informational presentation on the Proposition 65 listing mechanisms.
  • Received an informational presentation on how the National Toxicology Program evaluates reproductive and developmental hazards and about its new Office of Health Assessment and Translation (OHAT).
  • Discussed the petition filed by the Polycarbonate/BPA Global Group of the American Chemistry Council to reconsider the designation of the “National Toxicology Program, solely as to final reports of the Center for the Evaluation of Risks to Human Reproduction” (NTP-CERHR) as an authoritative body.
  • Discussed whether to change the designation of the NTP as an authoritative body in light of the establishment of OHAT.
  • Advised OEHHA on the prioritization of candidate chemicals for future DARTIC review and listing decisions.
  • Received updates on recent Proposition 65 activities.

SUMMARY OF THE LISTING DECISION FOR SULFUR DIOXIDE

Following a staff presentation, comments from the public and committee discussion, the DARTIC determined that sulfur dioxide has been clearly shown to cause developmental toxicity based on findings of low birth weight in scientific studies.  The chemical was added to the Proposition 65 chemical list as known to cause reproductive toxicity (developmental toxicity endpoint) effective July 29, 2011.  The DARTIC did not find that sulfur dioxide has been clearly shown to cause female or male reproductive toxicity.
