Air pollution has become the major environmental risk factor for human health in urban areas like DKI Jakarta, Indonesia. Despite the increased number of ambient monitoring stations, there is a lack of published personal exposure data on air pollution. This study aims to provide comprehensive data on PM2.5 and carbon monoxide (CO) personal exposure of people doing activities in DKI Jakarta, starting from July 2022 to June 2023. Participants carried two low-cost sensors (LCS) around their respiratory area during their 24-hour activities. Results revealed that students had higher PM2.5 exposure (12.36 ?g/m3 ) compared to office workers (9.98 ?g/m3 ). The highest average PM2.5 exposure occurred during motorcycle rides (45.88 ?g/m3 ) for all participants, while the highest average CO exposure was measured in public transportation (14.54 ppm). The outside air and anthropogenic factors (smoking and cooking) contributed to high PM2.5 exposure, while vehicle emissions during travel contributed to high CO exposure. Indoor activities led to increased PM2.5 exposure, influenced by activity duration, while CO exposure was highest when using public transportation and motorcycles. Daily PM2.5 exposure for 2 office workers and 1 student was considered unsafe, indicating a non-carcinogenic health risk (RQ > 1). However, CO exposure was deemed safe for all participants.
