Abstract
Environmental and personal samples were analyzed for polynuclear aromatic (PNA) compounds including polycyclic aromatic hydrocarbons and aromatic amines, benzene (71432), toluene (108883), xylene (1330207), anilines, phenols, carbon-monoxide (630080), and hydrogen- sulfide (7783064) at five coal liquefaction (SIC-3312) pilot facilities. The industrial hygiene programs were reviewed. The most significant exposures were from PNA. The geometric mean of the area PNA concentrations ranged from 3.9 to 133.8 micrograms per cubic meter at the facilities. Most of the PNA were 2 and 3 ring compounds. Highest PNA exposures were connected with maintenance activities in the process areas. The concentrations of the other substances were rarely above the detection limits. Wipe samples showed the presence of PNA compounds containing up to 5 rings. Most occupational health programs included a preemployment physical, annual checkups, and a termination physical. Protective clothing was provided by all facilities; however, most facilities did not monitor clothing or personnel for residual contamination. The authors conclude that workers at all facilities are exposed to PNA. Recommendations include establishing a standardized medical monitoring protocol and developing methods for decontaminating protective clothing and equipment.
