Consumer hazards of plastics.

The modern consumer is exposed to a wide variety of plastic and rubber products in his day to day life: at home, work, school, shopping, recreation and play, and transport. A large variety of toxic sequellae have resulted from untoward exposures by many different routes: oral, dermal, inhalation, and parenteral. Toxic change may result from the plastic itself, migration of unbound components and additives, chemical decomposition or toxic pyrolysis products. The type of damage may involve acute poisoning, chronic organ damage, reproductive disorders, and carcinogenic, mutagenic and teratogenic episodes. Typical examples for all routes are cited along with the activites of Canadian regulatory agencies to reduce both the incidence and severity of plastic-induced disease.

Blood fluorocarbon levels following exposure to household aerosols.

Measurement of blood fluorocarbon levels was carried out in subjects exposed to a number of household aerosol products containing fluorocarbon gases as propellants. All aerosols were used according to manufacturers' recommendations. The general purpose of the study was to determine whether with normal routine exposure to a wide variety of household aerosol products fluorocarbon could be found in the blood and if so, to check the potential toxicity of the levels reached. Daily exposure to aerosols according to the study regimen lasted four consecutive weeks; this period was preceded and followed by two weeks of abstention from exposure. At the end of each of the three periods a medical examination, including evaluation of cardiac function, respiratory function studies, and hematological and functional clinical biochemical tests was performed. All tests and assessments failed to show any indication of toxicity. No trace of fluorocarbon was found in any of the blood sampled at intervals during the study.
