Abstract

|
The impact of a considerable increase in traffic volume on the emission and concentrations of air pollutants was
investigated at three beaches (Haeundae (HB), Gwanganri (GB), and Songjeong (SB)) in Busan during beach opening period (BOP) in 2011. During the BOP, passenger car was the major vehicle type, followed by taxi, and van. CO was the major contributor of total air pollutant emissions followed by NOx, VOC, and PM10. For the temporal variation of the emission of air pollutants during the BOP, it was generally the highest in the afternoon followed by the evening and morning, except for SB.
For the spatial variation of their emission, it was the highest at GB followed by SB and HB. The emissions of air
pollutants during the BOP were generally higher than those during the Non-BOP, except for HB. In contrast, the significant
impact of the traffic volume increase on the concentrations of air pollutants at monitoring sites near the three beaches during the BOP were not found compared to the Non-BOP due to the significant distances between monitoring sites of air pollutants and monitoring sites of traffic volume at the beaches.
