Description

Both public health and environmental concern have been generated by the identification of an assemblage of halogenated organic compounds produced in the chlorination of drinking water, sewage, and power plant cooling waters. Our objectives were to determine which compounds contributed significantly to the toxicity of such chloro-organic mixtures and whether significant interaction occurred. Toxicity studies were conducted using the embryo of the carp (Cyprinus carpio) and the cladoceran Daphnia pulex. Data are presented from studies of survival time, reproduction, and teratogenesis following exposure of various growth stages to three synthetic chloro-organic effluents in decade concentration steps from 10/sup -2/ mg/l … continued below

Our objectives were to determine which compounds contributed significantly to the toxicity of such chloro-organic mixtures and whether significant interaction occurred. Toxicity studies were conducted using the embryo of the carp (Cyprinus carpio) and the cladoceran Daphnia pulex. Data are presented from studies of survival time, reproduction, and teratogenesis following exposure of various growth stages to three synthetic chloro-organic effluents in decade concentration steps from 10/sup -2/ mg/l to 100 mg/l of total organics plus controls. It seemed apparent that the chlorinated phenols in the mixtures were responsible for the observed toxicity of the synthetic effluents.
