Background: Assessments and evaluations of particle characteristics (PM) from various sources, become very important to protect humans and the environment. The purpose of this study was to assess the environmental and children health risks due to exposure to breathing air containing PM of 2.5 from the cement industry around the settlement. Research Methods: The method used in data analysis is linear regression statistical test to determine the relationship between PM2.5 air quality with outdoor activities by children and respiratory disorders experienced. Health risk analysis and environmental risk were calculated using the equations provided by the EPA and WHO. To determine the magnitude of risk received by the environment and children if exposed to PM2.5 within a certain period of time. Direct measurements in the field were carried out in the morning until noon, with 23 sample points measured level of PM 2.5 pollution during June 2021. Results: The measurement results showed that the highest level of PM 2.5 concentration at the time of measurement was at station 10 in Bungaeja Elementary School, station 17 in Tukamasea Village and station 18 at Miftahul Rahman Mosque, Tukamasea Village with values of 0.490, 0.466 and 0.455 mg/m3 respectively. While the lowest is in the location; Salenrang Bontoa Village 1 with a value (0.060), Baruga Village, Near Factory Truck Parking (0.060), and in Salenrang Bontoa Village 2 (0.0905). The results of laboratory analysis for soil samples from 23 points in the research location showed that the highest points were respectively located at the station near the Jabal Rahmah Mosque, Maccini Baji Village, with a concentration of (2876), in the Mattoangin area (2358) and in Dusun Manarang, Tukamasea ( 2158). On the other hand, the lowest was in Pajjaiyang Hamlet (1083), Bungaeja Village, Tukamasea (1190), and Ammansangeng, Baruga (1263). The calculation of the Potential Hazard Quotient (HQ) for the highest inhalation route is 880.78, and 852.43 while the lowest is 82.88 and 92.83. Furthermore, for the HQ value via the dermal route, the highest values were 0.012 and 0.011 while the lowest HQ values were 0.003 and 0.004 all without units. The results of the calculation of ecological risk for ambient air show that the highest and most risky values are 7.54 and 7.15 while the lowest are 0.92 and 1.46 units less. Furthermore, the highest ecological risk values for soil intake were 287 and 235 while the lowest were 119 and 126 without units. Conclusion: Health risks through the inhalation route all exceed the standard >1 and the potential for pulmonary disorders in children can occur, while the risk from the dermal route is still <1 which means it is still safe. most of the children that frequently expose to dust of PM 2.5 have experienced to suffer from lung diseases and at risk.
