摘  要:
以皱纹盘鲍(Haliotis discus hannai)为受试生物,采用半静态生物测定方法,研究了苯、甲苯、邻二甲苯、间二甲苯和对二甲苯对皱纹盘鲍的急性毒性效应,获得了5种苯系物对皱纹盘鲍的24 h、48 h、72 h和96 h半致死浓度(LC_(50))。研究表明,苯系物对皱纹盘鲍的毒性作用存在明显的剂量-效应相关关系,苯系物对皱纹盘鲍的96 h LC_(50)分别为苯33.37mg·L~(-1)、甲苯25.24 mg·L~(-1)、邻二甲苯15.61 mg·L~(-1)、间二甲苯12.84 mg·L~(-1)、对二甲苯4.81 mg·L~(-1);5种苯系物对皱纹盘鲍均为高毒物质,毒性大小顺序为:对二甲苯>间二甲苯>邻二甲苯>甲苯>苯。

摘  要:
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.
