title: Vinyl chloride concentrations in maxillofacial prosthetics laboratories.
abstract: Air sampling was conducted in three maxillofacial laboratories to determine whether vinyl chloride, a carcinogen, was released during the formulation of polyvinylchloride facial prostheses. Results show that time-weighted average exposures of technicians were less than 0.1 ppm, a concentration meeting current U.S. Department of Labor standards.
