测定了壬基酚对淡水无脊椎动物大型水蚤的急性和慢性毒性。按平均测定浓度计算，固定化后24和48h的急性EC50值分别为0.30和0.19 mg/L。在另一项单独的研究中，在21天的时间里测量了壬基酚对大型金龟子存活、生长和繁殖的影响。根据平均测量浓度计算的未观测到的有效浓度为0.024毫克/L，比急性值低约一个数量级，比报告的最高环境水平高一个数量级。
The acute and chronic toxicity of nonylphenol to the freshwater invertebrate Daphnia magna has been determined. The acute 24 and 48 h EC50 values, based on immobilization, were 0.30 and 0.19 mg/l, respectively, using mean measured concentrations. In a separate study, effects of nonylphenol on survival, growth and reproduction of D. magna were measured over a period of 21 days. The no observed effect concentration (NOEC), based on mean measured concentrations, was found to be 0.024 mg/l. This is approximately one order of magnitude below the acute value and one order of magnitude higher than the highest reported environmental levels.
