Summary: | High selenium (Se) concentrations in the water and sediment of San Francisco Estuary are of potential health concern for both humans and wildlife. Results from 2002 bird tissue analysis showed that Se concentrations from Suisun Bay for surf scoter and greater scaup were significantly higher than tissue concentrations in San Pablo or South Bays. Most of the 2002 Se concentrations, except 2002 Suisun Bay scaup, were significantly lower than the peak year Se tissue concentrations that occurred during the late 1980s. There is, however, high inter-annual variation in the data. Additional sampling and data are neccessary to see any long term trends in tissue accumulation. Surf scoter gut content in Suisun Bay was 100% |
