China Environmental Science, 2014,34(5)：1310~1315 Abstract ：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, Port
