溢油污染物对紫贻贝的急性毒性效应
|
摘要
选择紫贻贝(Mytilus edulis)作为受试生物,测定燃料油、原油分散液(WAF)以及添加消油剂后的乳化液(DWAF)对紫贻贝的急性毒性效应参数。结果表明,随着溢油污染物浓度的升高,紫贻贝的死亡率逐渐增大;当浓度为5 mg/L时,各实验组中紫贻贝的死亡率达60%以上。加入消油剂后,燃料油对紫贻贝的急性毒性效应降低,而原油升高。
The Mytilus edulis was taken as subjects to test the toxicity of crude and fuel oil water accommodated fractions( WAF) and their dispersed water accommodated fractions( DWAF). According to the result,with the increase of the concentration of spilled oil pollutants,its death rate is increasing; the death rate is more than 60% with the concentration of 5 mg/L. After adding the oil dispersant,the acute toxicity effect of the fuel oil decreased,and the crude oil increased.
