Press Releases

A draft report containing the proposed advisory and OEHHA's evaluation of potential health threats posed by mercury in certain fish from five reservoirs and portions of the Bear and South Yuba rivers and Deer Creek (Nevada, Placer and Yuba counties).

Announcement of the withdrawal of the 2.5 ppb PHG for chromium, in order to develop a PHG specifically for chromium 6, or hexavalent chromium.  The new PHG will replace the withdrawn "total chromium" PHG, which consists of both chromium 6 and chromium 3, a less toxic form of the metal.

Dioxin, lead, particulate matter emissions from diesel-fueled engines, polycyclic organic matter and acrolein were identified as toxic air contaminants that may cause children and infants to be especially susceptible to illness. 

A scientific panel of experts convened by the University of California has submitted to OEHHA a review of health issues relating to the presence of chromium 6 in drinking water.  The committee's report presented information on a key German study used by OEHHA in 1998 to develop a PHG of 2.5 ppb for total chromium.

The California Environmental Protection Agency, on behalf of OEHHA, has asked the University of California (UC) to establish a blue-ribbon panel of expert scientists nationwide to review scientific questions concerning the potential of chromium 6 to cause cancer when it is ingested. The UC panel's review will provide recommendations to assist OEHHA in the development of a chromium 6 PHG.
