AB  - Current-use pesticides (CUPs) are widely used in agriculture, and some are listed 
      as persistent organic pollutants (POPs) due to their bioaccumulative and toxic 
      properties. China is one of the largest producers and users of pesticides in the 
      world. However, very limited data are available about the environmental fates of 
      CUPs. Four CUPs (trifluralin, chlorothalonil, chlorpyrifos, and dicofol) in 
      surface seawater and low atmospheric samples taken during research cruises on the 
      Bohai Sea in August and December 2016 and February 2017 were analyzed, we added 
      the spring data sampled in May 2012 to the discussion of seasonal variation. In 
      our study, chlorpyrifos was the most abundant CUPs in the gas phase with a mean 
      abundance of 59.06+/-126.94pgm(-3), and dicofol had the highest concentration 
      dissolved in seawater (mean: 115.94+/-123.16pgL(-1)). The concentrations of all 
      target compounds were higher during May and August due to intensive use and 
      relatively high temperatures in the spring and summer. Backward trajectories 
      indicated that air masses passing through the eastern coast of the Bohai Sea 
      contained high concentrations of pollutants, while the air masses from the Bohai 
      and Yellow Seas were less polluted. The high concentration of pollutants in 
      seawater was not only influenced by high yields from the source region of 
      production or usage, but also by input from polluted rivers. Volatilization from 
      surface water was found to be an important source of trifluralin and chlorpyrifos 
      in the air. Air-sea gas exchange of chlorothalonil underwent strong net 
      deposition (mean FRs: 51.67), which was driven by higher concentrations in air 
      and indicates that the Bohai Sea acted as a sink for chlorothalonil.
