摘要
实验测定２，４－ＤＮＴ对鲤鱼的急性和亚急性毒性．亚急性试验经１．６４０、３．２８０、４．９１９、６．５５９、９．１０９ｍｇＬ－１２，４－ＤＮＴ暴露３６ｄ，在１５—１９℃下，２４、４８、７２、９６ｈ的ＬＣ５０值分别为３０．７８、２７．９８、２５．８４、２４．９６ｍｇＬ－１．亚急性试验中，根据２，４－ＤＮＴ对鲤鱼生长和肝ＡＴＰａｓｅ活力的影响，求得２，４－ＤＮＴ的最大允许毒物浓度为１．６４０—３．２８０ｍｇＬ－１．
The purpose of this work is intended to determine the acute and subacute toxicity of 2,4 DNT on carp. Carp was exposed to 2,4 DNT with concentrations of 1.640,3.280,4.919,6.559,9.109 mg·L -1 for 36 days.The 24h,48h,72h,96h,LC 50 for capr was 30.78,27.98,25 84,24.96mg·L -1 at 15—19℃,respectively.With regard to the subacute toxicity test,the maximum allowable toxicant concentration (MATC)of 2,4 DNT for carp was 1.640—3.280 mg·L -1 ,as decided from the toxic effects of 2,4 DNT on their growth and ATPase activity of liver.
