Abstract
This study analyzed the effect of forests on reducing particulate matter by investigating the particulate matter concentration and influencing factors between urban forest and traffic forest. The concentrations of particulate matter in Hongreung Experimental Forest (urban forest) and a forest (traffic forest) formed at the intersection of Cheongryangri Station in Dongdaemun-gu, Seoul were measured with the light scattering method instrument from January to November 2018. During the study period, the average PM10 concentrations in the urban forest and the traffic forest were 12.5㎍/m3 and 15.7 ㎍/m3, respectively, and the average PM2.5 concentrations were 16.6㎍/m3and 6.9 ㎍/m3, respectively. Comparing the concentration by the urban atmospheric measurement network of the Ministry of Environment and the concentration in urban forests showed that the reduction rate of PM10 was 66.9±28.6% in urbanforest and 58.6±44.1% in traffic forest and that of PM2.5 was 71.3±23.0% and 64.9±31.3%. The difference in the reduction rate of particulate matter is likely related to the size and structure of the urban forest, and the wind velocity is considered the reduction factor.
