The study aimed to assess the human health risk of PM 2.5 -bound heavy metals from anthropogenic sources in Khon Kaen Province, Thailand between December 2020 and February 2021. According to the findings, the geometric mean concentration of PM 2.5 in the university area, residential area, industrial zone, and the agricultural zone was 32.78 μg/m 3 , 50.25 μg/m 3 , 44.48 μg/m 3 , and 29.53 μg/m 3 , respectively. The results showed that the estimated human health risk assessment, in terms of non-carcinogenic risks among children and adults in an urban area (residential and university), industrial zone, and the agricultural area, was of hazard index (HI) value of >1.0 indicating a greater chance of chronic effects occurring. This study showed that exposure to PM 2.5 -bound heavy metal may increase the likelihood that lasting effects will result in a very high carcinogenic risk (CR) in children in residential areas, and an industrial zone with total carcinogenic risk (TCR) values of 0.23 × 10 1 , and 0.12 × 10 1 , respectively while resulting in a high TCR of 3.34 × 10 − 2 and 4.11 × 10 − 2 within the university areas and agricultural zone, respectively. In addition, health risk assessments among adults demonstrate high TCR values of 4.40 × 10 − 1 (residential area), 2.28 × 10 − 1 (industrial zone), and 7.70 × 10 − 3 (agricultural zone), thus indicating a potential health risk to adults living in these areas while the university area was very low effects on carcinogenic risk ( CR...
