Abstract

Concentrations of butyltin compounds (BTs), including tributyltin (TBT) and its metabolites, di-(DBT) and monobutyltin (MBT), and total tin (n=organic +inorganic tin) were determined in various tissues and organs of marine mammals collected from Japanese coastal waters. Some marine mammal species from Hong Kong, India, Philippines, Black Sea and North Pacific Ocean were analyzed for comparison. Among the organs and tissues analyzed. concentrations of Sigma BTs (TBT+DBT+MBT) and Sigma Sn were the highest in the liver. Concentrations of Sigma BTs and Sigma Sn in most coastal species were higherthan those in offshore species, indicating a greater input of tin compounds in coastal waters. Lower hepatic concentrations of Sigma BTs and ratio ofSigma BTs to Sigma Sn observed in pinnipeds may be attributed to higher metabolic capacity to degrade BTs and to their excretion through hair shedding. Age trends in accumulation of both Sigma BTs and Sigma Sn showed increasing concentrations in immature growth stage and stable levels in mature animals. A significant correlation was observed between the hepatic concentrations of Sigma BTs and Sigma Sn in marine mammals. These findings suggest a significant input and/or bioaccumulation of anthropogenic tin. A significant correlation was found between concentrations of Sigma BTs (as wen as Sigma Sn) in hair and liver of pinnipeds, suggesting that hair can be used as an indicator for monitoring butyltin contamination in the body of pinnipeds under non-killing condition.
