| 研究对苯二胺对泥鳅的急性毒性并进行安全性评价。在实验室条件下,以染发剂的主要成分对苯二胺为诱变剂,采用半静水试验法,研究了对苯二胺在不同浓度(0、15、17.85、21.24、25.27和30mg/L)和不同染毒时间(24、48、72和96h)条件下,对泥鳅(Misgurnus angullicaudatus)的急性毒性作用。结果表明:对苯二胺24、48、72和96h的LC50分别是39.40、27.93、23.69和18.78mg/L,安全浓度为4.21mg/L。根据有毒物质对鱼类的急性毒性标准,对苯二胺属于高毒性污染物(LC50在1～100mg/L),建议染发时谨慎使用,并关注染发污水排放对环境的影响。 |

| The thesis studied on Acute Toxicity of P-phenylenediamine on Misgurnus angullicaudatus and its safety evaluation. The method was that in Lab test taking p-phenylenediamine from hair dye as mutagen，through water bioassay，the acute toxicity of p一phenylenediamine of different contentration as 0，15，17. 85，21.24，25.27 and30 mg/L and different contamination time as 0，15，17.85，21.24，25.27 and 30 mg/L on Misgurnus angullicaudatus were observed. The results showed that after 24，48，72 and 96 h the LC50 were 39. 40，27. 93，23.69 and 18. 78 mg/L，respectively，and its safety concentration was 4.21 mg/L. According to the toxicity satandard，p-phenylenediamine belongs to hypertoxic contaminant. It is suggested to use hair dye prudently and to concern the hair dye sewage discharge has an effect on environment. |
