title: [Pollution of fish and shellfish with organotin compounds and estimation of daily intake].
abstract: Tributyltin (TBT) and triphenyltin (TPT) compounds have been widely used as antifouling paint for ship bottoms and fishery firm nets, and they are known to be aquatic environmental contaminants. A survey of the pollution with organotin compounds in fish and shellfish has been carried out for samples (180 samples from 43 kinds) which were collected in the Hokkaido prefecture during the period from February, 1989 to September, 1992. On the other hand, daily intakes of organotin compounds have been investigated using the Market Basket Method. Relatively high concentrations of TBT and TPT were detected from flat fish and shellfish such as Hirame (bastard halibut), Kurogarei (black plaice), Asari (Japanese littleneck), Hokkigai (Japanese surf clam) and Kaki (oyster). The maximum value of TBT in samples was 0.38 microgram/g (for both Asari and Kaki), and TPT was 0.47 microgram/g (Kurogarei). Estimated daily intakes of DBT, TBT and TPT were 0.45 microgram, 2.40 micrograms and 4.11 micrograms, respectively. The values presented in this study were lower in comparison with the acceptable daily intake. It was revealed that the values of the organotin compounds in this study were not so high as to have any efect on human health at the present.
