The subchronic oral toxicity of polyphenylene sulfide

Polyphenylene sulfide was offered to Charles River CD rats for 6 months in the diet at concentrations of 0.00, 0.50, 2.75 and 5.00% (w/w). In this study, animals of both sexes consumed polyphenylene sulfide for 6 months without exhibiting compound-related effects. Parameters studied were: body weight, hematology, clinical chemistry, urinalysis, organ weights, gross pathology and histopathology.
