Tributyltin and its breakdown products, mono- and di-butyltin, were determined in water birds collected from Lake Huron (the Great Lakes), marine coastal United States, and the west coast of British Columbia, Canada. Concentrations of butyltins in the liver of birds collected from Lake Huron were </= 27 ng/g, wet wt, whereas those from marine coastal areas contained up to 90 ng/g. Relatively higher concentrations were found in seaducks collected from coastal British Columbia, with concentrations as great as 1,100 ng/g. Mollusk-feeding seaducks seemed to accumulate greater concentrations of butyltins than predatory birds feeding on fish, other birds and small mammals. Hepatic concentration ranges of butyltins in birds from the United States and Canada were compared with those reported for the UK, Netherlands, Japan, and Poland. Exposure of birds to butyltin compounds continues to occur in harbors and marinas where TBT is used on vessels greater than 25 m in length.
在从休伦湖（五大湖之一）、美国沿海海域以及加拿大不列颠哥伦比亚省西海岸采集的水鸟体内，测定了三丁基锡及其分解产物单丁基锡和二丁基锡的含量。从休伦湖采集的鸟类肝脏中丁基锡的含量≤27纳克/克（湿重），而来自沿海海域的鸟类肝脏中丁基锡含量高达90纳克/克。在从不列颠哥伦比亚省沿海采集的海鸭体内发现了相对较高的含量，高达1100纳克/克。以软体动物为食的海鸭似乎比以鱼类、其他鸟类和小型哺乳动物为食的食肉鸟类积累了更高浓度的丁基锡。将美国和加拿大鸟类肝脏中丁基锡的浓度范围与英国、荷兰、日本和波兰报告的浓度范围进行了比较。在长度超过25米的船只上使用三丁基锡的港口和码头，鸟类仍会接触到丁基锡化合物。
