摘要

On December 9-10, 1981, NIOSH conducted an evaluation of a coal tar pitch roof tear-off, and the application of hot asphalt. A total of 16 personal breathing-zone total dust samples were collected on seven workers. Analyses of the bulk tear-off dust indicated 0.07 milligrams (7%) of cyclohexane solubles per milligram of bulk material. The bulk dust analysis revealed the presence of several PNA's including phenanthrene, anthracene, pyrene, benz(a)anthracene, chrysene, benzo(p)fluoranthene, benzo(k)fluoranthene, and benzo(a)pyrene, and trace amounts of quartz and asbestos. NIOSH considers coal tar products carcinogenic and conditions should be made to keep exposures as low as possible. Current NIOSH research indicates that asphalt products are carcinogenic to laboratory animals and, therefore, may be more toxic to humans than previously believed.
