Abstract
The temporal trend of antifouling substances in aquatic environment has been clarified by measurement of the organotin compounds in water, sediment, and biological samples. The concentrations of tributyltin (TBT) compounds in water and mussels decreased dramatically after regulation, and no changes of TBT concentrations were then observed. TBTs in fish also decreased moderately, Whereas no changes of TBTs were observed in sediment. Although triphenyltin (TPT) compounds in water, sediment, and biological samples decreased after regulation, TPTs were still detected in fish. The partition coefficients of organotin compounds for water and sediment or biological samples ranged from 103 to 105. The concentrations of Sea-Nine 211, Diuron, Irgarol 1051, pyrithions, and M1 were measured in an aquatic environment for 2 years. Higher concentrations of Diuron and Irgarol 1051 occurred in the summer season. The concentrations of Sea-Nine 211, Diuron, and Irgarol 1051 in sediment increased during the observation period. The partition coefficients of Sea-Nine 211, Diuron and Irgarol 1051 for water and sediment ranged of 102-103.
