Seasonal Variations of Particulate Matter Capture and the Air Pollution Tolerance Index of Five Roadside Plant Species

Particulate matter (PM) is the most dangerous type of air pollutant and harmful to human health. Plants can be used as a biofilter remove PM from atmosphere improve quality. In this study, we pollution tolerance index four leaf traits five different plant species commonly in landscaping Korea determine which plants are best suited roadside areas spring, summer, autumn. We found that concentrations impacted amount accumulated plants, with increased accumulation during periods environmental levels on roadside. Euonymus japonicus, alatus highest had pollution. Thus, these could suitable for use high also shrubs were more effective accumulating than trees recommend together further increase removed urban areas.
