As the gasification of coal has progressed technically, in several facilities having reached the commercial/industrial stage of development, researchers have also been conducting investigations of the health and environmental implications of various gasification technologies; a sizable amount of these data has been reported over the past decade. In this report, the authors present a compilation of the health and environmental data now available on coal gasification and make a preliminary evaluation of the information. The report addresses two tasks: first, to determine the scope and adequacy of the existing data for the characterization and understanding of health and environmental issues; second, to begin establishing suitable standards for reducing and abstracting the existing data for inclusion in the gasification technology data base of the Morgantown Energy Technology Center (METC). The report includes background information of coal-gasification studies; a summary of the toxicological and chemical data now available on gasification; and an analysis of selected subsets of the health and environmental data base, focusing on Ames mutagenicity findings for materials at all gasifiers studied and on the toxicological and chemical data on materials produced by the METC gasifier. The report also includes four appendixes, one of which contains one-page summaries of 116 publications relevant to the focus of this data-compilation effort. 4 figures, 20 tables.
