This study aimed to determine the mass concentration levels of inhalable air particulate matter (PM10) and the effects of meteorological parameters on their dilution and dispersion, specifically within the Rustenburg area. The PM10 was collected using a Tapered Element Oscillating Microbalance (TEOM) at two sampling sites, RMINE and RCBD. The findings revealed that RMINE, which is closer to the mining industry, exhibited significantly higher hourly PM10 levels (ranging from 6.5 to 215.7 µg/m³), daily levels (44.4 to 151.7 µg/m³), and monthly levels (94.1 to 131.0 µg/m³) compared to RCBD, where the respective levels were 10.3 to 81.7 µg/m³, 44.2 to 49.3 µg/m³, and 44.2 to 49.3 µg/m³. Additionally, the data indicated that PM10 concentrations were dispersed over large areas (approximately 100 km for RMINE and 120 km for RCBD) with varying levels of dilution. Furthermore, the study noted a correlation between PM10 levels and meteorological variables, demonstrating an increase in PM10 concentrations as wind speed and relative humidity decreased, and as temperature increased. The air quality index classified the PM10 levels in RMINE as moderate to very unhealthy, while in RCBD, it ranged from moderate to unhealthy for sensitive groups.
