| 摘 要： | 采用鲤鱼和黑斑蛙进行了丙烯腈、乙腈、硫氰酸钠和二甲基甲酰胺等４种污染物的鱼类和两栖类胚胎幼体毒性试验．结果表明，４种污染物对鲤鱼的慢性毒性值分别为２．２６、５５６、２８．３和１１３１ｍｇ／Ｌ，已腈、硫氰酸钠和二甲基甲酰胺对黑斑蛙的慢性毒性值分别为２８２８、５６．５和４５２５ｍｇ／Ｌ，说明采用胚胎幼体试验能够有效地预测污染物的慢性毒性效应．

| Abstract: | Four pollutants, including acrylonitrile, acetonitrile, sulphocyanic socdium and dimethyl formamina,were studied for their short--tem chronic toxicity to embryo-larval fish and amphibians (Cyprinus carpio and Ranaa nigromaculata.) The results indicated that the chronic values of the four pollutants to carp were 2. 26,56, 28. 3 and 1131 mg/L respectively,and those of acetonitrile,sulphocyanic sodium and dimethyl formamina to Rana mgromaculata were 2 828, 56. 5 and 4 525 mg/L respectively. The results also showed that embryol--larval test might effectively predict the chronic toxicity of pollutants. |
