Development of methodologies to assess the relative hazards from thermal decomposition products of polymeric materials

Abstract
The physiological stress imposed upon mice due to the irritating properties of thermal decomposition products of polymeric materials was evaluated. Acute lethality and histopathological evaluations were included in the study. The rankings of the polymeric materials studied from most to least hazardous was concluded to be polytetrafluoroethylene>polyvinyl chloride>Douglas Fir and flexible polyurethane foam>fiber glass reinforced polyester>copper coated wire with mineral insulation.
