Since the adoption of the European Charter on Environment and Health in Frankfurt-am-Main in 1989, the countries of the WHO European Region have been placing greater emphasis on the role of their environmental health services in the protection of public health and the environment. The introduction of the Environmental Health Action Plan for Europe, in Helsinki in 1994, further enhanced the need for strong national and local environmental health services. The aim of this book is to provide guidance on key issues relating specifically to staffing that should be considered in the reform of environmental health services in the WHO European Region. The development of staffingpolicy for these services must be considered within the wider context of a country’s political, social and economic situation, as well as national environmental healthneeds. This book is intended to assist Member States in adapting the general principles of environmental health to addressing these political, social and economic needs.
