Organotin contamination in fishes with different living patterns and its implications for human health risk in Taiwan.
Contaminated levels of butyl- and phenyltin compounds, tributyltin (TBT), dibutyltin (DBT), monobutyltin (MBT), triphenyltin (TPT), diphenlytin (DPT), and monophenyltin (MPT), were investigated in pelagic, demersal and cultured fish species from different seasons and locations in Taiwan. Seasonal variations were found in fishes from Wuchi and Hsingta fishing harbors for their butyltin levels (winter>summer) with the opposite trend for phenyltins in fishes from Patoutzu fishing harbor and demersal fishes from four fishing harbors (summer>winter). Fish liver contained the lowest percentage of TBT and the highest percentage of TPT among six organotin compounds. Consumption of contaminated pelagic species and fishes from Hsingta fishing harbor had the highest hazard index. However, the hazard quotients and hazard indices were all less than 1, suggesting a daily exposure at these levels of TBT, DBT and TPT may not be likely to cause any deleterious effects during lifetime in human population.
