IMPACT OF EXTENSIVE GREEN ROOF ON THE REMOVAL OF PARTICULATE MATTER

ABSTRACT
This paper investigates the impact of extensive green roof on ambient PM1, PM2.5, and PM10 concentrations. During summer, particulate matter (PM) concentrations in ambient air were measured above the green roof and reference roof of a school building in the urban environment. The backward trajectory of air mass from the HYSPLIT model was used to access the particle’s emission source. The results show that green roof reduces PM concentration in ambient air by up to 67% and improve the air quality index. The larger impact was observed for PM1 particles, which are the most dangerous for human health. The high correlation coefficients for the ratio of PM2.5/PM10 concentrations were found above both roofs, indicating fine particulate dominance. The findings of this paper can help the large-scale adoption of green roofs to mitigate air pollution.
