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.
