    Abstract

    The toxicity of chlorine to one estuarine copepod, Acartia tonsa, appeared to be a simple dose response, that is, doubling the times of exposure had the same effect on mortalities as doubling the concentration of the toxicant. Chlorine toxicity to at least one of the other species tested, Eurytemora affinis, did not follow a simple dose response; changing the times of exposure affected mortalities differently, depending on the dose concentration and the temperature. The relative toxicity of chlorine to the four species tested varied with time and temperature.
