Developmental and Reproductive Toxicant Identification Committee (DARTIC) Members

The Developmental and Reproductive Toxicant Identification Committee (DARTIC) is a group of expert scientists appointed by the Governor to identify chemicals that have been clearly shown through scientifically valid testing according to generally accepted principles to cause reproductive toxicity. (Cal. Health & Safety Code § 25249.8).

A Committee of Experts

The Developmental and Reproductive Toxicant Identification Committee (DARTIC) includes experts from among the following areas of specialization: epidemiology, developmental toxicology, reproductive toxicology, teratology, medicine, public health, statistics, biology, toxicology, and related fields.

An Expert Determination

The committee meets at least once each calendar year.

The addition of a chemical to the Proposition 65 list by the committee requires three steps:

  1. During the months prior to each meeting, scientists from the Office of Environmental Health Hazard Assessment prepare hazard identification materials, commonly in the form of a hazard identification document, presenting the scientific evidence on a chemical’s reproductive toxicity. The public has an opportunity to submit relevant information to OEHHA that may be included in the materials.  The hazard identification materials are released to the public for a 45-day comment period.  Committee members then review the materials as well as the public comments received.
  2. At the meetings, committee members have a chance to hear public testimony on the chemical and then review, discuss, and vote on the evidence they have seen and heard.  
  3. Members will vote to add a chemical to the Proposition 65 list only if “it has been clearly shown through scientifically valid testing according to generally accepted principles to cause reproductive toxicity.” (Cal. Health & Safety Code § 25249.8).  Members usually will further specify whether the chemical has been clearly shown to cause male reproductive toxicity, female reproductive toxicity and/or developmental toxicity.

The committee has developed guidance for its use in identifying chemicals for listing under Proposition 65 as reproductive toxicants.

Members of the committee also have the authority to suggest and prioritize chemicals for future review. They also identify the “authoritative bodies” (such as the U.S. Environmental Protection Agency) whose formal identifications of reproductive toxicants qualify chemicals for listing. (Cal. Health & Safety Code § 25249.8).
