Effects of air pollution on European ecosystems

Poor air quality not only harms human health; it also impacts the structure and function of ecosystems, often far away from the emission sources. This report focuses on the deposition of airborne sulphur (S) and nitrogen (N) compounds and their negative effects on ecosystems. N- and S-containing air pollutants are released to the atmosphere by combustion processes such as the burning of coal or petrol, and by non-combustion processes such as agricultural fertiliser application.
