摘要
试验测定了氯化铵对草鱼的急性和亚急性毒性。急性试验采用26,47,60和125日龄的草鱼,亚急性试验用60日龄草鱼种,经0.970,0.455,0.099,0.054和0.012(对照)毫克NH3/升(未离解氨,un-ionized ammonia)暴露45天。26,47,125日龄草鱼的96小时LC50(半数致死浓度)分别是0.570,1.609和1.683毫克NH3/升,而47,60,125日龄的48小时LC50则分别为1.727,2.050和2.141毫克NH3/升。急性毒性试验结果表明,26日龄草鱼最为敏感。在亚急性毒性试验中,根据氨对草鱼生长和鳃组织的影响,求得未离解氨的最大允许毒物浓度为0.054—0.099毫克NH3/升。
