The major goal of this research effort is to assess inhalation hazards to plant workers and the general population that may be associated with low Btu coal gasification. Secondary goals are characterization of potential toxicants in liquid and solid process and waste streams. To these ends, the experimental low Btu gasifier at METC has been sampled to determine aerosol components in gaseous process streams and to assess potential toxicants in liquid and solid effluent streams with the most recent sampling effort in December 1979. Although this report concentrates on results obtained from December 1, 1979, to June 1, 1980, the following summary is intended to organize all data to date and draw tentative hypotheses which will be subjected to further testing in future sampling and analysis efforts. Diluting and/or cooling low Btu producer gas, as would happen in fugitive releases, produces a dense, respirable aerosol. Toxic element concentrations are higher in aerosols from clean gas than from raw gas streams at METC. Gasifier operating conditions have little effect on the elemental composition of cleaned gas aerosols.
