The rapid deterioration of the environment in many countries around the world, or of segments and aspects of the environment in specific locations, made it necessary that immediate - even if only short term - solutions be found to as many of these problems as possible. Nevertheless, in the long run, long range and long term solutions must be found taking into account the effects of one country or region on another as well as of the inter-action between the different types of pollution over extended periods of time. It was the purpose of the Tel Aviv meeting on Pollution: Engineering and Scientific Solutions, to address presently known or foreseeable "environmental insults;" that is, to focus on those aspects of air, noise, land, water or any other environmental quality for which there already exist engineering, scientific, legal or other solutions. Consequently, people from all disci- plines which are relevant to environmental problems and their solutions were invited to participate.
