摘　　要：[目的]为水产养殖业生产捕捞环境的水质科学管理提供理论依据。[方法]以麦穗鱼仔鱼为材料,研究了苯酚、铬对麦穗鱼的急性毒性以及苯酚对其的遗传毒性。[结果]苯酚对麦穗鱼仔鱼24、48、72、96 h的半致死浓度(LC50)分别为53.236、47.039、38.729和36.56 mg/L;铬对麦穗鱼仔鱼24、48、72、96 h的LC50为366.367、319.530、284.205和190.757 mg/L。苯酚和铬对麦穗鱼仔鱼的安全质量浓度分别为0.365 6和1.907 57 mg/L。在染毒96 h后0～42 mg/L浓度范围内苯酚对麦穗鱼仔鱼微核的产生具有明显的影响,且随着浓度的升高而增加。[结论]苯酚对麦穗鱼属于高毒物质,而铬对麦穗鱼属于中等毒性物质。[Objective] The aim of the research was to provide the theoretical basis for the aquaculture production of fishing environment water quality management.[Method] Pseudorasbora parva were taken as materials to study the acute toxicity of phenol and K2Cr2O7 and the genetic toxicities of phenol on the Pseudorasbora parva.[Result]The LC50 of phenol for 24 h,48 h,72 h and 96 h was found to be 53.236,47.039,38.729,36.56 mg / L,respectively;LC50 of K2Cr2O7 was found to be 366.367,319.530,284.205,190.757 mg / L,respectively.The safety concentrations of phenol and K2Cr2O7 were found to be 0.3656,1.907 57 mg / L.After contamination 96 h,in the 0-42 mg / L concentration scope,phenol has the obvious influence to the Pseudorasbora parva’s micronucleus production,also significant increase in micronucleus rate along with the concentration ascension.[Conclusion] Phenol belongs to the high toxic substances to the Pseudorasbora parva,K2Cr2O7 is a moderately toxic substance to the Pseudorasbora parva.
