Abstract
Environmental exposure and toxicology of polyvinyl-chloride (9002862) (PVC) film thermal decomposition products are reviewed as they pertain to occupational exposures. The major emissions resulting from the hot-wire cutting of PVC meat wrapping film are di- 2-ethylhexyl-adipate (103231) and hydrogen-chloride (7647010). The former is not regarded as a problem. Hydrogen-chloride, however, can be detected by most persons at concentrations of 1 to 5ppm, and current occupational health exposure limits are 5ppm. It is suggested that some of the hydrogen-chloride released may be adsorbed to aerosol particles of di-2-ethylhexyl-adipate, particulates less than 5 micrometers in diameter, and thereby get past the defenses of the upper respiratory tract and deposit in the small bronchioles and alveoli resulting in lung irritation or injury. Complete information regarding the total spectrum of emissions from the thermal activation of price labels is not available. However, the major ingredient of such adhesives is dicyclohexyl-phthalate (84617).
