摘　　要：研究了渤海湾有机锡污染对野生脉红螺的潜在生态风险.结果表明,在大神堂海域和南排河海域野生脉红螺性畸变发生率分别为12.5%和6.48%,交接器指数分别为9.61和12.45.脉红螺肌肉组织丁基锡和苯基锡浓度总和分别为39.04ng.g-1和46.48 ng.g-1,消化腺组织中为32.09 ng.g-1和109.03 ng.g-1.基于肌肉组织三丁基锡(TBT)浓度得出TBT对脉红螺种群的风险商为0.024.以上结果表明,渤海湾有机锡污染对野生脉红螺种群具有一定风险.The present study evaluated the potential ecological risk of organotin compounds（OTs） to wild veined rapa whelk（Rapana Venosa） population in Bohai Bay.The results showed that the imposex rate was 12.5% and 6.48% in Dashentang and Nanpaihe coastal areas,with relative penis size index of 9.61 and 12.45,respectively.The concentrations of butyltin compounds and phenyltin compounds were 39.04 ng·g-1dw and 46.48 ng·g-1 dw in muscle tissues,and 32.09 ng·g-1 dw and 109.03 ng·g-1 dw in digest gland,respectively.Based on TBT levels in the muscles of all samples,a risk quotient of 0.024 was derived,indicating certain risk of OTs at current levels to wild veined rapa whelk populations in Bohai Bay.
