Exposure of rats to the combined effect of HF and SO2 decreased body weight, O2 consumption and myoglobin levels in muscles and increased the erythrocyte level in blood. Low and high concentrations of HF and SO2 decreased cytochrome oxidase activity in almost all organs and had a toxic effect on succinate dehydrogenase activity in lung, liver and brain tissue. The combined effect of the 2 gases on most indices was of the summation type. [Application to chemical industry facilities is suggested.].
