Pertinent abstracts from a survey of current (post-1976) research projects are categorized according to energy-related activity. Subjects include coal strip mines, oil refineries, oil shale operations, coal-fired power plants, geothermal energy production, coal liquefaction plants, and potential quality control standards. Research projects and reports conducted before 1976 are compiled in Identification of Components of Energy-Related Wastes and Effluents (EPA-600/7-78-004) (PB-280 203). Abstracts of available technical reports are also presented using the same energy categories. These reports were obtained from a variety of sources. Computer searches of several data bases, including MEDLINE, TOXLINE, BIOSIS, CAIN, NTIS, DIALOG, and Chemical Abstracts, have been conducted. Federal energy research centers supplied a large number of pertinent documents. This state-of-the-art summary is provided as an aid to researchers concerned with the environmental effects of energy-related activities.
