Inhalation toxicity of vinyl chloride and Vinylidene chloride*
Exposure of mice to 1000 ppm of vinyl chloride (VC), 6 hr/day, 5 days/week, caused some acute deaths with toxic hepatitis and marked tubular necrosis of the renal cortex. Starting the sixth month, mice exposed to 1000, 250, or 50 ppm of VC became lethargic, lost weight quickly, and died. Only a few mice exposed to 50 ppm survived for 12 months. Pulmonary macrophage count was elevated in some mi...
متن کاملComparative mammalian metabolism of vinyl chloride and vinylidene chloride in relation to oncogenic potential.
Elucidation of the role of vinyl chloride metabolites in the various reaction sequences which comprise the metabolic pathway, including the interaction of reactive metabolities with some purine and pyrimidine residues of target-organ DNA, provides some explanation for the (oncogenic) properties associated with the original substance. Comparative investigation of the biological fate of vinyliden...
متن کاملPharmacokinetics of vinylidene chloride.
Dear Sir: The recent article by McKenna et al. (1) on phar-macokinetics of vinylidine chloride (VDC) in the rat has evoked a number of thoughts. These relate both to one detail of data presentation from the excellent experimental studies and to the general role of pharmacokinetics in supporting risk assessment from high dose studies in mammals. The detail concerns Figure la (Figure 2 of the McK...
متن کاملWorker exposure to vinyl chloride and poly(vinyl chloride).
The National Institute for Occupational Safety and Health (NIOSH) in early 1974 began industrial hygiene studies of vinyl chloride exposed workers. Three VC monomer plants, three VC polymerization plants, and seven PVC fabrication plants were surveyed. V polymerization plant workers and workers in one job category in VC monomer plants were exposed to average levels above 1 ppm. The highest aver...
متن کاملCarcinogenicity studies on vinylidene chloride.
Results of a study on Wistar rats regarding a possible carcinogenic effect of vinylidene chloride (VDC) were presented previously by one of the authors. Due to the unclear character of these results, a second inhalation study was initiated with Sprague-Dawley rats. Groups of 60 animals were exposed to 100 and 75 ppm VDC, along with one control group. A final report on the pathological results m...
