Control strategies for photochemical oxidants across Europe

The Project on the Control of Major Air Pollutants (MAP) was conducted within the framework of the activities of the Organisation for Economic Co-operation and Development (OECD) Air Management Policy Group. The goals of the project were to assess pollution by large-scale, short-term photochemical oxidant episodes in western Europe, to identify major emission sources, and to analyze possible control options including control technologies and their costs. The project also evaluated the impact of economically feasible control scenarios. The work was supported by other projects on photochemical oxidants modeling and assessment conducted by the Commission of the European Communities (CEC) and by a bilateral program of Germany and the Netherlands named PHOXA. However, the project did not include problems related to local photochemical smog, long-term photochemical pollution, or the increase of ozone in the free troposphere
