Chloropentafluorobenzene: short-term inhalation toxicity, genotoxicity and physiologically-based pharmacokinetic model development.

Ten Fischer 344 rats and six B6C3F1 mice of each sex were exposed to air, 0.25, 0.80, or 2.50 mg chloropentafluorobenzene (CPFB)/liter of air for three weeks, excluding weekends. Exposure to 2.50 mg/liter caused a reduction in the growth rate of rats but did not affect the growth rate of mice. Following the exposure there was reduced SGOT activity in the blood serum of exposed rats and a dose related increase in liver weights. Increased liver weights were observed in mice as well; the response in the female groups was clearly dose dependent. Histologically the livers of both rats and mice presented single cell necrosis. In exposed mice hepatocytes exhibited mild hepatocytomegaly with increased granular eosinophilic cytoplasm. In evaluations for its potential to induce chromosomal damage following this exposure regimen, CPFB did not alter the rate of bone marrow cellular proliferation. Assessment of the micronucleated polychromatic erythrocytes and normochromatic erythrocyte populations during the inhalation exposures indicated a general absence of genotoxic activity.[1]
