在本研究中的有机锡化合物的水平进行了测定，从零售市场购买的鱼类和贝类在新泻，日本。采用FPD-气相色谱法分别测定了二丁基锡（DBT）、三丁基锡（TBT）、二苯基锡（DPT）和三苯基锡（TPT）化合物的含量。研究了8种鱼类（黄尾、金枪鱼、墨鱼、橄榄比目鱼、北方虾、肉桂比目鱼、日本鲈鱼和牡蛎），每个季节每个物种分析5个样品，即一个季节40个样品，总共160个样品。在感兴趣的化合物中，检测到DBT、TBT和TPT。检测到的最高浓度为0.674微克/克DBT、0.669微克/克TBT和0.186微克/克TPT。DBT的检出量与TBT相当，但其浓度与TBT浓度无相关性。DBT和TBT浓度的平均值的季节变化观察。在一些物种中，如黄尾鱼和日本鲈鱼，这些有机锡化合物的混合污染也很明显。本研究是阐明环境中有机锡化合物对人体健康危害的第一步。
In the present study the levels of the organotin compounds were determined in fish and shellfish which were purchased from retail markets in Niigata, Japan. The concentrations of dibutyltin (DBT), tributyltin (TBT), diphenyltin (DPT) and triphenyltin (TPT) compounds were separately determined by FPD-gas chromatography. Eight species (yellowtail, tuna, cuttlefish, olive flounder, northern shrimp, cinnamon flounder, Japanese sea bass and oyster) were studied and five samples of each species were analyzed in each season, which meant 40 samples in one season, and 160 in total. Among the compounds of interest, DBT, TBT and TPT were detected. The highest concentrations detected were 0.674 microgram/g for DBT, 0.669 microgram/g for TBT and 0.186 microgram/g for TPT. DBT was detected as much as TBT, however, its concentration was not correlated with that of TBT. Seasonal changes of the mean value of the concentration of DBT and TBT were observed. In some species, such as yellowtail and Japanese sea bass, combined contaminations of these organotin compounds were also evident. This study is the first step to elucidate possible health hazards by environmental pollution of organotin compounds on human beings.
