摘要
本文通过石油烃分散液对华贵栉孔扇贝的急性毒性试验,经SPSS的probit分析结果表明,石油烃分散液对华贵栉孔扇贝的24 h LC50、48 h LC50、72 h LC50和96 h LC50浓度依次是233.08、147.30、81.67和75.16 mg/L,安全浓度Sc是17.65 mg/L。通过生物富集试验结果显示,华贵栉孔扇贝在120 h内对石油烃的富集效果与浓度和时间成正比。石油烃分散液胁迫下对华贵栉孔扇贝血清中POD、SOD酶活的影响呈现出低浓度促进、高浓度抑制的特征,并对其肝、鳃组织AKP酶活性具有促进作用。
In this paper,acute toxic experiment of petroleum hydrocarbon water- accommodated fractions was done on Chlamys nobilis. The results showed that acute toxic data of 24 h LC50,48 h LC50,72 h LC50 and 96h LC50 were 233. 08,147. 30,81. 67 and 75. 16 mg / L respectively,and the safe concentration was 17. 65 mg /L. Accumulation effects of different concentrations of petroleum hydrocarbon water- accommodated fractions were also done on Chlamys nobilis. The results showed that accumulation effects were proportional to concentration and time in 120 hours. In stress of different concentrations of petroleum hydrocarbon water- accommodated fractions,the activitiy of POD and SOD in Chlamys nobilis showed characteristics of promoting by low concentration and inhibiting by high concentration,and the activitiy of AKP in liver and gills in Chlamys nobilis could be promoted.
