Air Quality and Ecological Impacts reviews the characterization of air quality as it pertains to specific emission sources and their environmental effect. Since emissions from multiple sources impact the same location, a multidisciplinary approach is needed to relate atmospheric processes to terrestrial vegetation. As global industrial expansions continue, air quality is no longer governed by isolated point sources (e.g., a single coal-fired power plant), but by source clusters or complexes. To address these issues, atmospheric receptor models have been developed and are continually...
