Acute toxic effects of benzene,toluene,o-xylene,m-xylene and p-xylene on Haliotis discus hannai were investigated using the semi-static bioassay. LC_(50) values of the five chemicals acting on Haliotis discus hannai at 24 h,48 h,72 h and 96 h were obtained. The results indicated that there were significant positive correlations between the toxic effects on Haliotis discus hannai and the concentrations of the five chemicals in aquatic environment. The 96 h LC_(50) values of benzene,toluene,o-xylene,m-xylene and p-xylene were 33. 37,25. 24,15. 61,12. 84 and 4. 81 mg·L~(-1),respectively,which suggesting that these five chemicals were all highly toxic to Haliotis discus hannai and the toxicity was in the sequence of p-xylene m-xylene o-xylene toluene benzene.
