Results of RMP monitoring of loads from the Delta to San Francisco Bay were recently published in the journal Water Environment Research. The article follows up on a paper published in 2009 in Environmental Toxicology and Chemistry describing mercury concentrations and loads from this large river system to the Bay. This new article presents estimates for PCBs for a 6-year monitoring period and estimates for PAHs, PBDEs, dioxins and furans, the organochlorine pesticides DDT, chlordane, dieldrin, and selenium for shorter periods.
