AB  - As a class of persistent organic pollutants (POPs), the spatial and temporal 
      distribution of polychlorinated biphenyls (PCBs) in seawater is important for 
      environmental assessment. Surface water samples were collected from 35 stations 
      during summer and 36 stations during autumn of 2020 in the Bohai Bay. The 
      concentration, composition, distribution and sources of PCBs were analyzed to 
      assess the ecological impact of PCBs. The average concentration of  summation operator(18)PCBs was 
      124.6 ng/L (range of 28.1-445.5 ng/L) in summer and 122.8 ng/L (range of 
      21.0-581.4 ng/L) in autumn. PCBs in surface seawater of the Bohai Bay showed high 
      near-shore and low far-shore characteristics, indicating the serious influence of 
      land-based sources such as port activities and river inputs. Proportion analysis 
      showed that Tetra-PCBs and Penta-PCBs were the major constituents in most 
      stations. It was assessed as moderate and high risk (MRQ > 0.1) by mixture risk 
      quotient (MRQ) and concentration addition (CA) model in surface seawater of the 
      Bohai Bay. Principal component analysis (PCA) was used to explain the sources of 
      PCBs in the Bohai Bay. PCBs in the Bohai Bay may come from commercial PCBs and 
      their incineration products, municipal landfills, wood and coal combustion, and 
      industrial activities, etc.
