Abstract

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.
