Description
Summary:Common cormorants Phalacrocorax carbo were collected from Lake Biwa, Japan, and the organ-specific burden, biomagnification, and effective elimination of butyltin compounds were studied. Highest concentrations were found in liver and kidney, followed by skin, fat, lung, and heart. Two peaks patterns of higher butyltins concentrations were found in primary feathers of all birds examined. The calculated body burdens of mono-, di-, and tributyltin were 97, 72, and 16 mu g, respectively, while the organ-specific butyltin burdens in muscle, feather, skin, liver, kidney, and bone were calculated at 25, 25, 20, 10, 6, and 5%, respectively, of the whole body values. Of the three compounds, monobutyltin was dominantly retained. Feathers were found to play an important role in butyltin excretion.
