Biological assay systems using indigenous holo- and meroplankton were designed to model the chlorination patterns of power plants. A matrix of chlorine concentrations and exposure patterns permitted the generation of response isopleths that were then applied to developing design criteria. The marine phytoplankter, Thalassiosira pseudonana showed a 50% reduction in photosynthesis when exposed to 0.15 ppm Cl2 for 10 minutes, and complete growth inhibition after 5 minutes exposure to 0.3 ppm. Microzooplankton adults were somewhat less sensitive in that a 5 minute exposure at 2.5 ppm was necessary to produce 50% mortality. Larval and juvenile fish were sensitive to chlorine levels less than 0.2 ppm for exposure periods of sixty to ninety minutes. Two field studies were evaluated and compared to laboratory data with specific emphasis on the use of ATP to monitor entrainment and damages.
