| 摘 要： | 以采自清洁水体的河蚬(Corbicula fluminea)为实验生物,利用生物富集实验测试了河蚬对太湖梅梁湾水源地沉积物中HCHs和DDTs的生物富集.研究结果表明,将河蚬暴露于有机氯农药污染程度相似的太湖梅梁湾沉积物中(HCHs和DDTs浓度分别为1.5-1.8.S/S(以干重计)和1.1-1.7 as/g(以干重计))后,随着暴露时间的延长(24～168h),河蚬对有机氯农药的富集量随着暴露时间逐渐增加.试验结束时各样点中河蚬对HCHs和DDTs的富集量分别为(9.4±2.2)ng/g(以干重计)、(20.7±7.6)ng/g(以干重计).实验水体沉积物中HCHs和DDTs的生物沉积物富集因子(BSAF)分别为1.5±0.1和4.4±0.7.生物-沉积物富集因子(BSAF)与有机物的辛醇-水比值(Kow)存在显著正相关.
