| الوصف: | —Concentrations of organotin compounds (OTs) were determined in various body organs and tissues of adult common cormorants (Phalacrocorax carbo) collected from Lake Biwa, Japan. Several kinds of OTs were detected in various organs and tissues of adult common cormorants. Among the organs and tissues in which several kinds of OTs were detected, the highest concentrations of butyltin compounds (BTs), tributyltin (TBT) and its metabolites, were found in the liver (384 ng/g wet wt) and kidney (371 ng/g wet wt). Compared with BTs, phenyltin compounds (PTs), di (DPT) and triphenyltin (TPT), showed relatively uniform distribution among organs and tissues. Feathers showed significant higher concentrations of both PTs and BTs than the soft tissues and organs. This indicates possible excretion of OTs through molting feathers, similar to the trend reported for methylmercury. Lower levels of BTs and PTs were observed in the liver collected in 2007 (BTs: 8.0 ng/g, PTs: 2.0 ng/g ww) when compared with those collected in 1993 (BTs: 270 ng/g, PTs: 130 ng/g ww). This result reflects the effect of the restrictions on the usage of TBT and TPT in Japan. A significant correlation was found between the concentrations of OTs in the feathers and liver of cormorants, suggesting that cormorant feathers can be utilized for monitoring OTs contamination as a non-destructive sample. |
