摘要
采用室内模拟天然海水养殖栉孔扇贝方法,通过石油烃单一污染实验与石油烃、Cd、Pb复合污染实验结果对比,探讨石油烃与重金属Cd、Pb复合污染下石油烃在栉孔扇贝体内的积累状况.结果表明:石油烃与不同种类及浓度的重金属复合污染条件下,石油烃在栉孔扇贝体内的积累状况有很大差异.与0.6 mg/L的石油烃单一污染相比较,石油烃-Cd、石油烃-Pb、石油烃-Cd-Pb的3种不同复合污染实验条件下,石油烃在栉孔扇贝体内的积累量都增大,说明实验设置浓度的Cd、Pb及其组合都促进了石油烃在栉孔扇贝体内的积累,但0.05 mg/L的Cd、0.50 mg/L的Pb以及0.03 mg/L的Cd+0.15mg/L的Pb组合3种情形更有利于促进石油烃在栉孔扇贝体内的积累.
Laboratary simulating accumulation of petroleum hydrocarbon in Chlamys farreri is studied. Experiments of single petroleum hydrocarbon pollution and combined pollution of petroleum hydrocarbon-heavy metal Cd-Pb are conducted. The results show that the accumulation of petroleum hydrocarbon in Chlamys farreri, compared with 0. 6 mg/L of single petroleum hydrocarbon pollution, increases in all three experiments： combining petroleum hydrocarbon with Cd, petroleum hydrocarbon with Pb, petroleum hydrocarbon with Cd and Pb. It also shows that the accumulation is significantly promoted when concentration of Cd and Pb are 0.05mg/L and 0.50mg/L respectively, or 0.03 mg/L Cd is combined with O. 15mg/L Pb.
