Notice of Intent to List chemicals known to cause reproductive toxicity via the authoritative bodies mechanism: Chlorsulfuron, Ethyl dipropylthiocarbamate, Quizalofop-ethyl, Dichlorophene, and 2,4-DP (dichloroprop)

Availability of draft data summaries and draft priorities for chemicals with respect to their potential to cause cancer.

Chemicals under consideration for possible listing as carcinogens via the Authoritative Bodies mechanism: Diethanolamine, polygorskite fibers, and pyridine.

In 1999, OEHHA adopted 20 Public Health Goals (PHGs) for chemicals in California drinking water.  These chemicals are: atrazine, bentazon, cadmium, chromium (withdrawn on 11/09/01), 1,2-dibromo-3-chloropropane (DBCP), 1,2-dichloroethane, 1,1-dichloroethylene, 1,2-dichloropropane, 1,3-dichloropropene, endrin, heptachlor and heptachlor epoxide, hexachlorocyclopentadiene, lindane, inorganic mercury, methoxychlor, thallium, toluene, 1,2,4-trichlorobenzene, and trichloroethylene.

The California Wildlife Biology, Exposure Factor, and Toxicity Database (CalEcotox) is a compilation of physiological and ecological parameters and toxicity data for a number of California fish and wildlife. Exposure factor reports contain all the CalEcotox exposure factor data for selected wildlife species.
