TI  - Potential Linkage between Heavy Metal Pollution Risk Assessment and Dissolved

AB  - Direct sewage discharge can cause severe damage to the water environment of the 
      river. However, the impacts of dissolved organic matter (DOM) in the discharge on 
      the original pattern of DOM and the distribution of heavy metals (HMs) in the 
      river are little known. How to monitor such areas in a long-term and systematic 
      manner also needs to be urgently addressed. In this paper, we characterized the 
      DOM of the sediments in the WWTPs (wastewater treatment plants)-river integrated 
      zone by ultraviolet-visible absorption spectroscopy (UV-vis), three-dimensional 
      excitation-emission matrix (3D-EEM) combined with parallel factor (PARAFAC) 
      method. The effects of WWTP on receiving waters were investigated, and the 
      potential link between DOM and HM pollution was explored. Hg (I(geo): 3.94 +/- 
      0.65; EF: 44.83 +/- 31.11), Cd (I(geo): 1.81 +/- 0.69; EF: 8.02 +/- 2.97), Cu (I(geo): 
      1.61 +/- 0.83; EF: 6.85 +/- 2.37), Zn (I(geo): 1.55 +/- 0.54; EF: 7.24 +/- 3.58), and Ni 
      (I(geo): 1.46 +/- 0.56; EF: 6.12 +/- 1.99) in rivers were the primary risk sources of 
      HM. The combined pollution risk indicates that the WWTPs-river integrated area is 
      in a high pollution risk state. Moreover, alpha(254) has a significant correlation 
      with pollution indicators and can be used as a proxy indicator. These results 
      help to understand better the impact of WWTPs on receiving water bodies and the 
      potential connection between DOM and HM pollution and provide new ideas for 
      monitoring the water environment in highly polluted areas.
