The Office of Research and Development (ORD) in the U.S. Environmental Protection Agency is responsible for providing EPA program offices with scientific and technical information on biotechnology products intended for environmental release. This includes research on genetically engineered microorganisms (GEMs) and biological control agents (BCAs). To accomplish this, ORD created a Matrix-managed program for Biotechnology/BCA Risk Assessment and designated the Gulf Breeze Environmental Research Laboratory as the lead laboratory. To assure coordination and promote multi-disciplinary research approaches, the Matrix manager holds periodic meetings attended by laboratory and headquarters scientists and cooperative agreement and contract researchers. This document is a compilation of extended abstracts of the research presented at the 1991 All-Investigators meeting, the fourth meeting of this type. Extended abstracts submitted from specially invited guests representing biotechnology efforts in Canada and several European countries reflect the international collaboration theme of the meeting. These invited abstracts are followed by scientific presentations from EPA laboratory, cooperative agreement and contract personnel separated into the three program element research areas: exposure, effects and risk control.
