Inventory of PM2.5 concentration at roadside using LVAS and particulate counter during the Covid-19 pandemic on Bandung urban road

Abstract

One of the sources of PM2.5 pollution in urban areas comes from road transportation activities. Therefore it is necessary to determine the concentration of PM2.5 roadside. The purpose of this study is to identify the concentration of PM2.5 in roadside ambient air on collector roads in Bandung City's collector roads during the pandemic of Covid-19. The inventory was carried out in October 2020 with two methods, a manual method using a Low Volume Air Sampler (LVAS) and an automatic method using a Particulate Counter. Measurement was conducted at 10 locations with a duration of 1 hour in the morning and afternoon. In addition, it was also carried out additional measures of two hours and twelve hours. Found that the ambient PM2.5 concentration measured with the LVAS is more fluctuating than the Particulate Counter measurement. Even though transportation activity tends to be lower during the pandemic, the ambient PM2.5 concentration for 1 hour ranged from 10.95 - 760.98 μg/m3. This condition has exceeded the air quality standard set by the Indonesian Government and WHO, which is 65 μg/m3 and 35 μg/m3. © 2023 Author(s).
