Geochemistry and Source Apportionment of Atmospheric Particulate Matter in Jiaozuo City

Abstract:

A total of 28 atmospheric particulate matter samples were collected at Henan Polytechnic University in the southeast of Jiaozuo city during October to December 2010. The daily concentrations of PM₁₀ vary from 190.76 to 670.14 μg/m³, with the average concentration of 359.36 μg/m³. The concentrations of Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Fe, Cu, Zn, Mn and Pb in PM₁₀ are determined by Energy Dispersive X-Ray Fluorescence (EDXRF). The result shows that the fifteen elements quality accounts for 17.3%~36.7% of total mass. The X-ray diffraction (XRD) results show that six minerals are identified in the atmospheric particles. They are quartz, gypsum, kaolinite, sal-ammoniac, calcite, and albite, which account for 29%, 29%, 18%, 17%, 4% and 3%, respectively. The principle component analysis (PCA) model is used for source apportionment of PM₁₀. The research results show that there are four sources: architecture/smelting action, coal combustion/traffic action, soil dust and particular industrial action.
