PESTAB. Thalossiosira pseudonana (strain 3H) was grown axenically in media containing methanol, DDT, DDE, and/or PCB. DDE and PCB alone inhibited growth to a minor extent, whereas together they inhibited it substantially. In contrast, DDT counteracted the toxicity of PCBs, whether added simultaneously with or 12-24 hours after the PCBs. Thus, the counteraction of PCB toxicity by DDT evidently involved an intercellular interaction. Interaction by DDT and DDE was only slight; growth inhibition caused by treatment with both substances (500 ppb each) was intermediate between that caused by either substance alone.
