海洋环境石油烃类污染物斑马鱼急性毒性效应研究

目的探讨海洋环境石油烃类污染物所致的斑马鱼急性毒性。方法根据急性鱼类毒性分级法.共分三个剂量组和一个空白对照组.采用静态染毒方式进行试验。结果在给予海洋环境石油烃类污染物后.100 mg/L剂量组2 h内斑马鱼全部死亡;10 mg/L剂量组24 h内斑马鱼全部死亡;而1 mg/L剂量组和空白对照组试验至96 h,所有斑马鱼均未死亡。结论该海洋环境石油烃类污染物的96 h斑马鱼LC50位于1~10 mg/L之间,判定为急性水生环境毒性Ⅱ级,提示石油烃类污染物对环境水生态可能会造成一定程度的影响。

Petroleum Hydrocarbon Distribution Features in Water and Sediment off Fujian Shore

This study on the distribution features of petroleum hydrocarbon in water and sediment off the Fujian shore using data obtained from the baseline research on oceanic contamination in Fujian showed that: during the research period, petroleum hydrocarbon concentrations in water varied from 5.77 μg/L to 37.28 μg/L, averaged 14.48 μg/L; was lower in the wet season than in the dry season; and was highest in the Minjiang Estuary and Jiulong Estuary in both seasons. The petroleum hydrocarbon concentrations in shore sediment varied from 14.48 mg/kg to 784.36 mg/kg, averaged 133.3 mg/kg, and was closely related to sediment types (granularity).
