Relationship between meteorological conditions and atmospheric PM_2.5 in uranium mining areas and source analysis

In this study, the relationship between PM_2.5 and ambient temperature, humidity, air pressure, wind speed and air indices was investigated by combining specific facilities at uranium mine with villages and cities. Humidity, atmospheric pressure and air quality index were positively correlated with PM_2.5 concentration, whereas temperature and wind speed were negatively correlated, while altitude had no correlation with PM_2.5 concentration. By constructing the corresponding PMF model data analysis, this study obtained six sources of eight metallic elements (U, Th, Al, Cu, Pb, Cd, Ti, Zn) in PM_2.5 around a decommissioned uranium mine.
