Effects of chlordecone [insecticide] on membrane integrity and respiratory behavior of isolated rat liver mitochondria (RLM) were studied. Treatment of RLM with chlordecone over a concentration range of 20-100 .mu.M produced membrane disruptions as evidenced by rapid, nonenergy-dependent swelling, permeability of inner mitochondrial membrane to exogenously supplied NADH and loss of protein. Over the range of concentrations tested, chlordecone stimulated state 4 respiration, inhibited state 3 respiration during the oxidation of glutamate and succinate.
