Abstract

Butyl- and phenyltin residues were quantified in seawater and Pacific oyster (Crassostrea gigas) from the Chinhae Bay System, Korea. Butyltin compounds were detected in all the seawater and C. gigas samples, whereas phenyltin compounds were not detected in any seawater samples. Tributyltin (TBT) concentrations in seawater ranged <8-35 ng Sn L-1. TBT and triphenyltin (TPhT) concentrations in oysters ranged 95-885 and 155-678 ng Sn g-1, respectively. Spatial distribution of TBT was closely related to boating and dry-docking activities. However, spatial distribution of TPhT was not consistent with that of TBT. The estimated biological concentration factor (BCF) for TBT in C. gigas was about 25,000. Furthermore, 19 and 28% of total body burdens of TBT and TPhT were found in gonadal mass of C. gigas just prior to the spawning period, indicating that a proportional amount of TBT and TPhT would be released with a following reproductive process.

摘要

对韩国镇海湾系统海水中的丁基锡和苯基锡残留物以及太平洋牡蛎（长牡蛎）进行了定量分析。在所有海水和长牡蛎样本中均检测到了丁基锡化合物，而在任何海水样本中均未检测到苯基锡化合物。海水中三丁基锡（TBT）的浓度范围为<8 - 35 ng Sn L-1。牡蛎中TBT和三苯基锡（TPhT）的浓度分别为95 - 885 ng Sn g-1和155 - 678 ng Sn g-1。TBT的空间分布与划船和船舶进坞活动密切相关。然而，TPhT的空间分布与TBT不一致。长牡蛎中TBT的估计生物浓缩系数（BCF）约为25,000。此外，在产卵期前，长牡蛎性腺中TBT和TPhT的全身负荷分别有19%和28%，这表明在随后的生殖过程中会释放出相应比例的TBT和TPhT。
