Chronic exposure to nitrogen dioxide (NO₂), particulate matter (PM₂.₅), and PM₁₀ can have negative impacts on both environmental and human health. This research aimed to determine the levels of NO₂, PM₁₀, and PM₂.₅ pollution in Makassar City and to assess the potential health risks for children and adolescents using the Monte Carlo Simulation (MCS) probabilistic approach for exposure to these pollutants in Makassar City, Indonesia. This analytic, cross-sectional study employed an MCS approach to evaluate health risks. The results showed higher NO₂ levels of 10.88 µg/m³ and 10.97 µg/m³ at stations 12 and 17 in Panakkukang and Borong, located near a truck parking area. Meanwhile, stations 21 in Tamalanrea Indah and 20 in Karampuang recorded higher PM₁₀ levels of 24.8 and 30.14 µg/m³, respectively. The hazard quotient (HQ) was 12.4, 20.3, and 19.8 for NO₂, PM₁₀, and PM₂.₅, respectively. Among children at the 5th and 95th percentiles, cancer risks for NO₂ were 13 and 34, corresponding to medium risk levels. In contrast, adolescents showed cancer risks of 102 and 223, indicating high risks. For adults, the sensitivity analysis for NO₂ revealed that the most significant factor contributing to health hazards was the length of exposure (ED) at 26.4%, followed by pollutant concentration (C) at 18.3%, exposure frequency (EF) at 17.8%, and inhalation rate at 17.2%, as shown in the sensitivity analysis chart. Overall, adolescents faced greater risks than children, with the highest HQ values in children being 8.98, 15.2, and 22.5 for NO₂, PM₁₀, and PM₂.₅, respectively, which were lower than those observed in adolescents. The total hazard quotient (THQ) risks for NO₂, PM₁₀, and PM₂.₅ were 12.4, 20.3, and 19.8, respectively. In conclusion, NO₂ and PM₂.₅ pose significant health risks to adolescents.
