In November 14-16, 1989, all investigators of research projects funded under the EPA Office of Research and Development (ORD) Biotechnology Risk Assessment Program assembled at the U.S. EPA Corvallis Environmental Research Laboratory for their third review of the research projects. Expanded abstracts presented at the meeting by EPA scientists and extramural cooperators supported by the Program. Fifty-three abstracts were presented during nine sessions that covered: development of recombinant microorganisms, detection and enumeration, dispersal and transport, gene exchange, effects of higher organisms, survival and colonization, molecular, physiological, and ecological approaches to the determination of environmental effects of GEMS, and risk control. A panel of scientific peers reviewed and offered analysis of the EPA-funded research, relevancy of research emphasis, and adequacy of research facilities. Their summary comments are included in the document.
