| 摘 要： | 通过对翡翠贻贝（Mytilus edulis）进行混合重金属积累与排放的慢性实验，研究了重金属铅（Ph）、锌（Zn）、铜（Cu）、镍（Ni）、镉（Cd）、铬（Cr）、汞（Hg）和砷（As）的混合溶液在翡翠贻贝体内的积累规律和排放规律。结果表明，翡翠贻贝对Ph、Zn、Cu、M、Cd、Cr、Hg和As的富集和排放规律性较强，在累积实验中，翡翠贻贝体内各种重金属含量随着时间的推移明显呈上升趋势，翡翠贻贝对重金属Pb，Cu，Ni，Cd，Zn、As、Cr和比有较强的累积能力，可很好地指示海水中这些重金属的污染；在排放实验中，翡翠贻贝体内各重金属含量随时间的推移呈下降趋势，但排放曲线都较平缓，表明翡翠贻贝在实验过程中，释放体内重金属较缓慢。

| Abstract: | The chronic accumulation and elimination of eight heavy metals: lead(Pb),zinc(Zn),copper(Cu),nickel(Ni),cadmium(Cd),chromium(Cr),mercury(Hg),and arsenic(As) in green mussel Mytilus edulis were investigated by exposing to the mixed heavy metal solutions.Results showed a positive relationship between exposure time and metal uptake in the accumulation experiment,indicating that M.edulis has a strong capacity of heavy metal accumulation and can be used as an indicator of marine heavy metal pollution,but a negative relationship between exposure time and metal elimination in metal elimination experiment.The elimination curve was to some extent flat,indicating that the elimination of the metals by the animal was slow at least during the experiment. |
