Environmental, health and safety assessments for direct coal liquefaction. Volume 7a. Potential health effects

OSTI ID:6095426

This document reviews potential exposures of workers in the direct coal liquefaction industry, potential exposures of the public, and the adverse health effects that may be associated with these exposures. Exposures to the largest concentrations of chemicals are likely to occur most often in the occupational population, primarily through insulation of aerosols and dermal contact with spilled or leaked process materials. The public is likely to be exposed by inhalation and ingesion (consumption of water, crops and/or animals contaminated by various synfuel chemicals). It is anticipated that the pollution control technology will monitor and control most chemicals to the extent that acute effects will probably not be evident for those substances being monitored. The major health concern may be the largely unknown effect of chronic, very low-level exposures. Several major classes of biological effects may be possible: carcinogenic, mutagenic, reproductive, cardiovascular, pulmonary, neurologic, and general toxic effects such as cytotoxicity, skin irritations, and under unusual conditions, acute lethality. Hydrotreatment of similar treatment reduces the apparent bioactiviy of these materials and probably decreases the probability of human health effects. 82 references, 3 figures, 15 tables.
