AB  - Magnetic method is a reliable and powerful technique for identification of the 
      relative contribution of industrial pollutants. However, it has not been fully 
      applied in urban area impacted by non-ferrous metal (NFM) smelting/processing 
      activities. The aim of this study is to explore the applicability of magnetic 
      methods for detecting heavy metal contamination in dust from three NFM 
      smelting/processing industrial cities (Ezhou, Zhuzhou, and Hezhang) in China. The 
      enhancements of magnetic susceptibility (MS) and saturation isothermal remanent 
      magnetization (SIRM) together with heavy metals were significant in the studied 
      areas in comparison with the background values. Scanning electron microscope 
      (SEM) analysis revealed that magnetic particles in dust from Ezhou were dominated 
      by spherules, while those from Zhuzhou and Hezhang were mainly consisted of 
      irregular-shaped particles. kappa-T curves and X-ray diffraction (XRD) analyses 
      indicated that the magnetic particles from Ezhou were dominated by magnetite and 
      metallic iron, whereas those from Zhuzhou and Hezhang were consisted of magnetite 
      and hematite. Our study indicates that magnetic properties of the dust are 
      sensitive to the NFM smelting/processing related heavy metal pollutants. However, 
      the relationship between magnetic parameters and heavy metals was influenced by 
      the presence of metallic iron particles and multi-sources of metal pollutants.
