Abstract

Abstract Daily intakes of tributyltin (TBT) and triphenyltin (TPT) compounds from meals in Shiga Prefecture, Japan, were investigated by 2 methods. Daily intakes of TBT and TPT by the duplicate portion method were, respectively, 4.7 and 0.7 μg in 1991 and 2.2 and 0.7 μg in 1992. Those by the market basket method were, respectively, 6.9 and 5.4 μg in 1991 and 6.7 and 1.3 μg in 1992. Daily intakes of TBT and TPT by the market basket method were higher than those by the duplicate portion method. These values were considerably lower than acceptable daily intakes of 80 μg/50 kg body weight specified by the Welfare Ministry of Japan for bis(tri-n-butyltin) oxide and of 25 μg/50 kg body weight specified by the Food and Agriculture Organization/ World Health Organization for TPT.
