Health Risk Analysis of PM

\nOver the past few years, increasing urbanization has resulted in higher concentrations of fine particulate matter (PM2.5), worsening health problems, particularly among one of vulnerable groups, children. This cross-sectional study is designed to evaluate the levels of PM2.5 exposures, the assess health risk associated with PM2.5 exposures, and their effects on lung function in primary school children in Bandung. The results indicated that the exposure to PM2.5 above the normal levels. School A had the highest average exposure (166.4 ± 77.2 µg/m³), followed by School B (156.8 ± 115.8 µg/m³), and School C (95.6 ± 46.7 µg/m³). Additionally, certain children showed an elevated risk (RQ>1). PM2.5 exposures was found to be negatively correlated with poorer lung function, as indicated by lower FEV1.0 and FVC scores. This study reveals concerning levels of PM2.5 in elementary schools in Bandung, indicating major health consequences such as impaired lung function in children. Immediate measures are required to alleviate the health effects of PM2.5 pollutions on children in Bandung.\n
