2. WHAT ARE AN AIRPORT’S IMPACTS?
www.aef.org.uk2-5 habitats still received too much acid deposition, and 59% too much eutrophying pollution (Defra, 2006). It is very difficult to reduce the air pollution impacts from aircraft except through more efficient operations and technology. The use of the most polluting chemicals is covered by pollution prevention and control regulations.
