In this study, toxic risk classification based on a battery of bioassays was proposed to assess and compare the toxicity of 17 effluent samples collected from around Bohai Sea coastal area. More than half of 17 effluent samples were of high toxicity (class III), which were mainly obtained from industrial outlets; significant toxicity effects were also observed for some of the sewage river samples. These results indicated that it is necessary to further study the quality and toxicity of both sea water and sediment of the adjacent marine environment, and to assess potential ecological risk due to the long-time discharge of those toxic effluents. The proposed method was effective and feasible for screening and evaluating the toxic risk of effluents discharged into sea.
