摘要

对四种海洋单细胞藻类进行了室内生物测定。生长7 d后的EC50值(以mg/l (ppm)计)分别为:绿球藻0.35、杜氏藻0.58、尼氏藻0.60、假海藻0.60。当暴露于100 μg/l (ppb) Kepone 24小时时，与藻类相关的残留物(以mg/kg (ppm)湿重为单位)为:氯藻，80;Nitzschia sp.， 41;pseudonana, 52岁。

Toxicity and uptake of Kepone in marine unicellular algae

Four species of marine unicellular algae were exposed to Kepone in laboratory bioassays. EC50 values after seven days’ growth, in mg/liter (ppm), were:Chlorococcum sp., 0.35;Dunaliella tertiolecta, 0.58;Nitzschia sp., 0.60;Thalassiosira pseudonana, 0.60. When exposed to 100 μg/liter (ppb) Kepone for 24 hr, residues associated with the algae, in mg/kg (ppm) wet weight, were:Chlorococcum sp., 80;D. tertiolecta, 23;Nitzschia sp., 41;T. pseudonana, 52.
