25 soil dust samples collected outside Nanjing Iron and Steel Group, China, from September to October 2020 are analyzed by a handheld X-ray fluorescence spectrometer. Ten heavy metal elements, including chromium (Cr), magnesium (Mn), iron (Fe), copper (Cu), zinc (Zn), mercury (Hg), lead (Pb), strontium (Sr), zirconium (Zr) and molybdenum (Mo), are quantified, and their impacts on local soil pollution are assessed by various statistical models. In addition, a receptor model, positive matrix factorization (PMF), is used for source apportionment of these heavy metals. It is shown that the concentrations of these heavy metals in the ground surface soils are Cr (260 ± 14 mg·kg-1), Mn (1550 ± 22 mg·kg-1), Fe (1.65 ± 0.01 mg·kg-1), Cu (67 ± 9 mg·kg-1), Zn (600 ± 13 mg·kg-1), Hg (16 ± 6 mg·kg-1), Pb (102 ± 7 mg·kg-1), Sr (275 ± 10 mg·kg-1), Zr (302 ± 5 mg·kg-1) and Mo (13 ± 3 mg·kg-1), respectively. Their averaged surface accumulation index is 2.13, indicating a moderate level of pollution. Individually, Hg is severely polluted, Mo is heavily polluted, Zn is moderately polluted, Cr, Fe and Pb are slightly-to-moderately polluted, Mn, Cu and Sr are slightly polluted, Zr is below the pollution level. It is found that most of the high concentration samples are taken from the north and northwest parts of the study area, where heavy metals are prone to accumulation. Three major sources of heavey metals in the study area are identified by the PMF analysis: industrial emissions (49.3%), domestic activities (30.7%) and automobile emissions (20.0%).
