| 摘 要： | 目的]研究有机-无机复合污染对扇贝积累石油烃的影响。方法]在实验室模拟条件下研究石油烃与Cu、Pb复合污染对栉孔扇贝积累石油烃的影响。结果]单一石油烃污染条件下,石油烃在栉孔扇贝体内的积累量随暴露时间的延长及石油烃浓度的增大都有明显增大趋势;复合污染条件下,石油烃在栉孔扇贝体内的积累量随暴露时间及污染物种类及浓度的变化发生着动态变化,且不同浓度处理组间差异很大,当石油烃浓度固定为0.6 mg/L时,不同处理浓度组的Cu、Pb及Cu与Pb组合都促进了栉孔扇贝对石油烃的积累,但低处理浓度组的Cu、高处理浓度组的Pb、低处理浓度组的Cu与Pb组合更有利于促进栉孔扇贝对石油烃的积累。结论]石油烃与Cu、Pb复合污染条件下,石油烃在栉孔扇贝体内的积累状况比单一石油烃污染条件下要复杂得多。

| Abstract: | Objective] To study the influence of the combined pollution of organic and inorganic compounds on petroleum hydrocarbon accumulation in Chlamys farreri.Method] The accumulation of petroleum hydrocarbon in the body of Chlamys farreri under the condition of combined pollution of petroleum hydrocarbon with copper,plumbum was experimentally studied.Result] Under pollution of single petroleum hydrocarbon,the accumulation of petroleum hydrocarbon in the body of Chlamys farreri presented an obvious trend of growth with the increase of exposure time and concentration of petroleum hydrocarbon as well;Under the condition of combined pollution,the accumulation of petroleum hydrocarbon in the body of Chlamys farreri had a dynamic trend with the increase of exposure time and the changes in the types and concentrations of pollutants.When the concentration of petroleum hydrocarbon was fixed at 0.6 mg/L,Cu,Pb and the combination of Cu and Pb in different treatment groups with different concentrations all had positive contribution to the Chlamys farreri’ accumulation of petroleum hydrocarbon.However,the treatment groups with low concentration of Cu and those with high concentration of Pb and those with low concentrations of Cu and Pb were more likely to promote the Chlamys farreri’ accumulation of petroleum hydrocarbon.Conclusion] The accumulation of petroleum hydrocarbon in the body of Chlamys farreri under the condition of combined pollution of petroleum hydrocarbon with copper,plumbum was much more complex than that under the condition of single petroleum hydrocarbon pollution. |
