Abstract
Environmental and breathing zone samples were analyzed for polynuclear aromatic (PNA) compounds including polycyclic aromatic hydrocarbons and aromatic amine, benzene (71432), toluene (108883), xylene (1330207), anilines, phenols, carbon-monoxide (630080), and hydrogen-sulfide (7783064) at three coal gasification (SIC-3312) facilities. Industrial hygiene programs were reviewed. The geometric mean of area PNA concentrations ranged from 0.2 to 26.8 micrograms per cubic meter (microg/m3). The means of the personal samples ranged from 0.4 to 389.4microg/m3. Highest PNA exposures were associated with maintenance activities in the process areas. Most of the PNA were 2 and 3 ring compounds. Carbon-monoxide and hydrogen-sulfide concentrations ranged up to 745 and 160 parts per million, respectively. Wipe samples showed the presence of PNA containing up to 5 rings. The other substances were rarely found at concentrations above the detection limit. All facilities provided physical examinations and periodic medical histories. Two provided skin examinations, urinalyses, and blood counts. Work practices were directed toward reducing skin contact with process components. These included isolation, draining and flushing, and cleaning. The authors conclude that workers at all facilities are exposed to PNA. They recommend developing methods for decontaminating protective clothing and equipment, and conducting studies on long term effects of PNA inhalation.
