AB  - This study explores the pollution characteristics, risks, and sources of heavy 
      metals in small-scale areas. Rongcheng District, Jieyang City, Guangdong Province 
      was considered as the study area and enrichment factor (EF), pollution load index 
      (PLI), potential ecological risk index (RI), and US EPA health risk assessment 
      model were used to evaluate its environmental risk. Moreover, the source 
      apportionment of heavy metals was analyzed through correlation analysis, the 
      characteristic of spatial distribution, and a PMF model. The results showed that 
      the mean concentrations of omega(Cr), omega(Hg), omega(As), omega(Pb), omega(Ni), omega(Cd), omega(Cu), and 
      omega(Zn) were 54.87, 0.25, 8.35, 56.00, 15.38, 0.35, 30.56, and 124.23 mg.kg(-1), 
      respectively. The mean concentrations of all elements exceeded the local soil 
      background value. In terms of EF level, Cr, As, Pb, and Ni showed negligible 
      accumulation; Zn and Cu showed minor accumulation; and Hg and Cd showed moderate 
      accumulation. The mean value of the pollution load index was 2.37, with a severe 
      pollution level, and the eight elements were in different pollution levels. In 
      total, the study region suffered severe ecological risk, Hg and Cd presented 
      strong ecological risk, and other elements presented slight ecological risk. The 
      non-carcinogenic risks under the three exposure paths were within the acceptable 
      level. The carcinogenic risks (CR) of adults and children were 9.81E-05 and 
      5.59E-04, respectively, and Cr and As were the main contributors of CR. The 
      results showed that the four sources of heavy metals were transportation sources 
      (37.02%), parent material sources (18.53%), atmospheric deposition sources 
      (26.49%), and industrial sources (17.96%).
