选择9种我国本土海洋生物对北部湾涠洲岛原油污染物的急性生物毒性进行测试,并基于测试获得的毒性数据,利用美国水生生物基准推算方法,对该原油污染物的海水环境基准阈值进行推导,结果表明：原油样品对卤虫、褶皱臂尾轮虫、太平洋纺锤水蚤、中国对虾、三疣梭子蟹、彩虹明樱蛤、牙鲆、半滑舌鳎、青岛大扁藻的LC50(或EC50)分别为10.28,2.37,4.88,0.31,0.81,65.88,19.02,9.10,0.23mg/L；涠洲岛原油污染物的急性和慢性海水质量基准阈值分别为0.06,0.012mg/L.研究结果可为我国海上溢油事故损害评估提供科学依据.

Acute toxicity of crude oil from Weizhou Island in the Northern Bay to nine kinds of native marine organisms was tested. According to the guidelines of development of aquatic life criteria recommended by USEPA, the marine environmental quality criteria for the crude oil pollutants were derived based on the nine toxicity data. The results showed that the LC50 (or EC50) values of Artemia saline, Brachionus plicatilis, Acartia pacifica, Fenneropenaeus chinensis, Portunus trituberculatus, Moerella iridescens, Paralichthys olivaceus, Cynoglossus semilaevis, Platymonas subcordiformis were 10.28, 2.37, 4.88, 0.31, 0.81, 65.88, 19.02, 9.10and 0.23mg/L, respectively. The acute and chronic marine quality criteria of the crude oil from Weizhou Island were 0.06and 0.012mg/L, respectively. The study provided valuable information for the oil spill damage assessment.
