摘　　要：[目的]了解不同油品对2种蟹类的毒性效应。[方法]选择国内外常见的4种原油和4种燃料油,通过油类母液制备和试验液配制,采用半静态试验法,研究不同油品对三疣梭子蟹和锯缘青蟹2种蟹类幼体的毒性效应。[结果]4种原油中,TJ016、TJ015、TJ014T、J002对三疣梭子蟹和锯缘青蟹2种幼蟹的96 hLC50分别为1 450.095和4 937.369 mg/L、744.342和4 008.723 mg/L、241.671和1 254.620 mg/L、926.612和1 181.351 mg/L。4种燃料油中,-20#柴油、F380、F120、F180对2种幼蟹的96 hLC50分别为1 195.187和405.041 mg/L1、72.168和5 497.524 mg/L、61.754和287.524 mg/L1、2.989和320.873 mg/L。[结论]8种油对三疣梭子蟹的毒性效应的大小顺序是:F180>F120>F380>TJ014>TJ015>TJ002>-20#柴油>TJ016,除-20#柴油外,燃料油比原油的毒性效应大;8种油对锯缘青蟹的毒性效应的大小顺序是:F120>F180>-20#柴油>TJ002>TJ014>TJ015>F380>TJ016,除F380外,燃料油比原油的毒性效应大。[ Objective] The aim of the study was to find out the toxicity effects of different oil products on two kinds of erab. [Method ] 4 kinds of crude petroleum and 4 kinds of fuel oil common at home and abroad were selected to study the toxicity effects of different oil products on the larvae of Portunus trituberculatus and Scylla serrata. [ Result ] Among 4 kinds of crude oil, the 96 h LC50 of the larvae of P. trituberadatus and S. serrata stressed by TJ016, TJ015, TJ014 and TJ002 were 1 450.095 and 4 937.369 mg/L, 744.342 and 4 008.723 mg/L, 241.671 and 1 254.620 mg/L, 926.612 and 1 181.351 mg/L resp. Among 4 kinds of fuel oil, the 96 h LC50 of tow crabs stressed by No. - 20 fuel oil, F380, F120, F180 were 1 195. 187 and 405.041 mg/L, 172.168 and 5 497.524 mg/L, 61.754 and 287.524 mg/L, 12.989 and 320.873 mg/L. [Conclusion] The toxicity intensity of 8 kinds of oil for the larvae of P. trituberculatus in order were F180 〉 F120 〉 F380 〉 TJ014 〉 TJ015 〉 TJ002 〉 No. - 20 fuel oil 〉 TJ016 and that for the larvae of S. serrata in order were F120〉 F180〉 No. - 20 fuel oil〉 TJ002 〉 TJ014 〉 TJ015 〉 F380〉 TJ016.
