摘  要：
采用室内试验研究方法,研究了五氯酚钠(PCP-Na)对2种规格的克氏原螯虾的急性毒性,并求出相应的安全浓度,结合人体PCP负荷相关指数(允许摄取的理论值),做出对人的食品安全评价。结果表明,体重在1.2～2.3g(平均体重为1.38g)左右的小虾的TLm24=80mg·kg-1,TLm48=67.5mg·kg-1,安全浓度为14.46mg·kg-1;体重在20.7～39.8g(平均体重为29.5g)左右的大虾的TLm24=750mg·kg-1,TLm48=500mg·kg-1,安全浓度为100mg·kg-1。

摘  要：
Cambarus clakii, originated in the north of Mexico and the south of America,was introduced into China by Japanese in the 1930s,and now distributed in more than 10 provinces. In some regions, it had become a predominant species and was one of the main and popular aquatic products of China. PCP-Na wasused extensively for killing snail in aquiculture and caused the water pollution due to its difficult degradating. The acute toxicity of sodium pentachlorophenate to Cambarus clakii and the resistance of aquatic animals to pesticide were studied. Tow size of Cambarus clakii was examined under five different concentrations of PCP-Na. The safe concentration for small Cambarus clakii weighting 1.2～2.3 g (the average being 1.38g) was 14.46 mg·kg-1, the concentrations of TLm24 and TLm48 were 80 mg·kg-1 and 67.5 mg·kg-1, respectively, while, for the big Cambarus clakii with weight about 20.7～39.8 g (the average being 29.5 g), the safe concentration was 100 mg·kg-1, the concentrations of TLm24 and TLm48 were 750 mg·kg-1 and 500 mg·kg-1, respectively. These results could be used in setting the standard about food sanitation of Cambarus clakii infuture.
