봄철 서울 도로변의 검댕 오염 특성 = Black Carbon Pollution Level at a Roadside of Seoul in Spring

다국어 초록 (Multilingual Abstract)

To understand particle pollution phenomena caused by vehicles, black carbon(BC) concentrations were contin-uously monitored using an aethalometer at a roadside in Seoul during the period of May 19 to 25, 2005. The BCBC concentration was observed between 2 and 5 a.m. The local highest BC concentrations were observed duringthe periods of both morning and evening rush hours. Change in trafc volume accounts for the trend of hourlyaveraged BC concentrations from the late evening to the morning. Particularly, the slower increase of BC concen-tration on Sunday seems to respond directly the lower trafc volume in the morning rush hours. From the compari-the distance from a road.
