摘要：

Tributyltin (TBT) surface water concentrations have significantly decreased in San Diego Bay following legislative restrictions on use of anti-fouling paints containing TBT in California. Current surface water concentrations in three of four regions studied in San Diego Bay are below the 6 ng liter-1 water quality criteria concentration adopted by the State of California for the protection of marine species. Regression analysis of surface water TBT measurements made over a 2 year period indicated that present concentrations would decrease by 50% in 8 months to approximately 2 years depending on the region studied. Tissue samples from the bay mussel, Mytilus edulis indicated that TBT measured in tissues generally decreased as water concentrations decreased. The majority of TBT concentrations measured in tissue samples were below levels reported to adversely affect mussel growth. Sediment TBT concentrations in San Diego Bay generally did not reflect recent decreases in water column values and were variable among stations over time.
