Fine particulates measuring 2.5 microns are a major component of air pollutants that disrupt environmental conditions and human health, especiallychildren because of their rudimentary immune systems. Bandung has geographical conditions in the form of basins that make pollutants difficult to spread. This study aimed to analyze the health risks of non-carcinogenic PM2.5 exposure in children in three elementary schools in Bandung City. The study design is an Environmental Health Risk Analysis (ERHA). PM2.5 concentration measurements are at 4 points in each school using an instrument in the form of a particulate counter, namely HTI HT9600. Respondents were students whose classrooms had PM2.5 concentration measurements measured. PM2.5 concentrations measured in all three schools showed that PM2.5 concentrations in classrooms were relatively greater than those in outdoor PM2.5 concentrations. PM2.5 concentrations from all three schools were conducted by the KruskalWallis non-parametric test which showed no significant difference between the location of schools in certain road categories and PM2.5 concentrations in school areas. To determine the level of health hazard due to exposure to PM2.5, a comparison is used between the average intake of PM2.5 received by students and the threshold value (RfC) set. This ratio is referred to as the Risk Quotient (RQ) and if the RQ is more than 1, then there is a risk that needs to be overcome. Based on analysis with exposure duration according to real time and projections of 6 years, it was found that PM2.5 exposure is still within safe limits.
