Industrial hygiene assessment of coal-gasification plants
Worker exposures to hazardous chemicals were evaluated at coal gasification facilities. Industrial hygiene surveys were conducted, and air samples were collected for analysis of polynuclear aromatic hydrocarbons, polynuclear aza heterocyclic hydrocarbons, aromatic amines, metals, common toxic gases, and other organic compounds. Sampling results indicated that workers were exposed to polynuclear aromatic hydrocarbons in the low microgram per cubic meter range, with the light molecular weight compounds in higher concentrations than the four through seven ring compounds. Some specific activities produced higher concentrations. Aromatic amines, phenolic compounds and simple aromatic solvents were occasionally present at very low levels.
