After the European Charter on Environment and Health was approved at the Minsterial Conference in Frankfurt-am-Main, in December 1989, the World Health Organization (WHO) and the Italian Government covened a working group to study the desirability and feasibility of setting up a European Centre on Environment and Health (ECEH). The main purpose of ECEH is to strengthen collaboration among European countries on the health aspects of environmental protection, with special emphasis on information systems, mechanisms for exchanging experience, and coordination of environmental research studies. Following a short introduction about the establishment of the first two WHO-ECEH centers (in Bilthoven, Netherlands, and in Rome), this pamphlet lists 23 specific conclusions and recommendations generated from the background papers, oral proposals, and detailed discussions. The appendices list the working documents background papers, and participants. (JJK)
