AB  - Polycyclic aromatic hydrocarbons (PAHs), a large group of persistent organic 
      pollutants (POPs), have caused wide environmental pollution and ecological 
      effects. Chromophoric dissolved organic matter (CDOM), which consists of complex 
      compounds, was seen as a proxy of water quality. An attempt was made to 
      understand the relationships of CDOM absorption parameters and parallel factor 
      analysis (PARAFAC) components with PAHs under seasonal variation in the riverine, 
      reservoir, and urban waters of the Yinma River watershed in 2016. These different 
      types of water bodies provided wide CDOM and PAHs concentration ranges with CDOM 
      absorption coefficients at a wavelength of 350 nm (a (CDOM)(350)) of 
      1.17-20.74 m(-1) and total PAHs of 0-1829 ng/L. CDOM excitation-emission matrix 
      (EEM) presented two fluorescent components, e.g., terrestrial humic-like (C1) and 
      tryptophan-like (C2) were identified using PARAFAC. Tryptophan-like associated 
      protein-like fluorescence often dominates the EEM signatures of sewage samples. 
      Our finding is that seasonal CDOM EEM-PARAFAC and PAHs concentration showed 
      consistent tendency indicated that PAHs were un-ignorable pollutants. However, 
      the disparities in seasonal CDOM-PAH relationships relate to the similar sources 
      of CDOM and PAHs, and the proportion of PAHs in CDOM. Overlooked and poorly 
      appreciated, quantifying the relationship between CDOM and PAHs has important 
      implications, because these results simplify ecological and health-based risk 
      assessment of pollutants compared to the traditional chemical measurements.
