Abstract

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