摘要：
Total suspended particle (TSP) and fine particulate matter (PM2.5) samples were collected continuously using an atmospheric particulate matter sampler at sampling points in a tailings reservoir in the south from October 28 to November 3, 2013. The mass concentrations of particulate matter in the air, the contents, and morphological analysis of heavy metal elements (Pb, Cd, U, Cu) were also studied. The results indicate that the air particulate matter concentrations exceed the mass concentration limits of national Grade II ambient air quality standard (GB3095-2012); The heavy metals content in air particulate matter from high to low order is: Pb > Cu > U > Cd and heavy metals are easier to be concentrated on fine particulate matter (PM2.5); heavy metal elements (Pb, Cd, Cu) exist mainly in the exchangeable morphology, especially the element Cd.
