Trends in ecosystem and health responses to long-range transported atmospheric pollutants

The aim of this trend report is to assess the effectiveness of air pollution policies under the UNECE Convention on Long-range Transboundary Air Pollution, and to document progress and identify remaining challenges. Trends in environmental and health responses to long-range transported air pollution are presented, primarily focusing on 1990 to 2012 and on Europe, with additional data from North America and the Arctic region
