도로먼지 및 교통 유래 비배기 입자의 화학적 특성화 연구

Abstract

Road dust and traffic-related sources have recently been recognized as significant causes of environmental pollution in major urban and coastal environments. As exhaust gas emission regulations for air quality have been strengthened in developed countries, non-exhaust emission (NEE) from transportation has been recognized as an essential source of environmental pollution. In addition, the increase in the intensity and frequency of heavy and extreme rainfall due to climate change can significantly increase the marine inflow of RD and tire and road particles (TRWP) from urban impervious surfaces such as roads of cities and coastal infrastructure. Due to these effects, research on the environmental fate and risk of road dust and road traffic-related sources is expected to become more important shortly. Previous studies conducted in several coastal areas, including the Busan coast, showed that coastal sediment was contaminated with RD and TRWP. For environmental forensics and fate studies of RD and TWRP, Methods are needed to precisely identify and characterize individual road dust and TRWP in complex environmental samples. Therefore, this study reviewed current characterization research trends for tracking RD and non-emission particles derived from road traffic, such as TRWP, brake pad wear particles (BWP), and attempted chemical characterization with stable isotopes and metals of road dust, tire particles, and brake pad particles collected in Busan.
