PESTAB. The effects of DDT and Aroclor 1254 (PCB) on marine phytoplankton were investigated. Fifteen Erlenmeyer flasks, each containing 100 ml of seawater and the nutrients necessary for growth of marine algae were used. All of these flasks were inoculated with the phytoplanktonic species Dunaliella tertioleca. Ten of the flasks then received a solution of the chlorinated compounds at a concentration of 1 ng/ml. The other five flasks served as controls. The flasks were then capped with aluminum and cultured at 13C. The distribution of organochlorine compounds was dtermined after 2, 24, 48, and 360 hr of phytoplankton growth. The concentration of these compounds in the filtrate, adsorbed on the walls of the flask, and on the aluminum used to cap the flasks was determined by the use of a gas chromatograph. The distributions were expressed as the arithmetic mean value of duplicate samples. The organochlorine compounds were found to have low solubility in the phytoplankton system.
