||Respiratory responses of mice exposed to thermal decomposition products from polymers heated at and above workplace processing temperatures

||Mice were exposed to thermal decomposition products released from acrylonitrile-butadiene-styrene (ABS), polypropylene-polyethylene copolymer, polypropylene homopolymer or plasticized polyvinyl chloride (PVC). These resins were heated in a temperature-programmable furnace, at and above workplace processing temperatures. Lethality (LC50) and respiratory effects (RD50) values were obtained on the basis of resin mass loaded in the furnace. LT50 values were determined at the respective LC50 masses. RD50 values were also obtained on the basis of particulate concentrations measured during heating of each resin. PVC and polypropylene homopolymer were more toxic and faster-acting than wood, while ABS and polypropylene-polyethylene copolymer were much more toxic and faster-acting than wood.
