Seasonal Air–Sea Exchange Dynamics of Polychlorinated Biphenyls Over the East China Marginal Seas: The Role of Water Masses in a Complex Coastal–Ocean Current System

“…Lower water-air volatilization fluxes of Σ ICEs PCBs were found over the Pacific Ocean (0.5-30.4 ng/m 2 /d) in 2006(Zhang & Lohmann, 2010, and the Indian Ocean (0.34-34 ng/m 2 /d) in 2011 (Huang et al, 2014). Net deposition fluxes of PCBs were found in the inland lake (Zhang et al, 1999), Arctic region , Tibetan Plateau (Ren et al, 2017) and (Guo et al, 2020), East China Sea (this study), Lake Baikal (McConnell et al, 1996), Lake Bourget (Masset et al, 2019), Lake Ontario, Lake Erie, Lake Superior, Lake Michigan and Lake Huron (Hillery et al, 1998), Norwegian Sea , Pacific Ocean (Zhang & Lohmann, 2010), Atlantic Ocean (Gioia, Nizzetto, et al, 2008), Indian Ocean (Huang et al, 2014), Mediterranean Ocean (Berrojalbiz et al, 2014), lake on the Tibetan Plateau (Ren et al, 2017), and Venice lagoon (Manodori et al, 2007). some regions in the open oceans (Berrojalbiz et al, 2014;Gioia, Nizzetto, et al, 2008) (Figure 3) due to different controlling factors.…”

“…In comparison of this work with other measurements of the PCB air–sea exchange fluxes, the PCB volatilization fluxes were generally higher in the river estuaries and continental marginal seas than those measured in the open seas (Figure 3). Volatilization fluxes of Σ ICEs PCBs were 54 ng/m 2 /d over Lake Bourget (Masset et al., 2019) and 170 ng/m 2 /d over the Yangtze River estuary (Guo et al., 2020). Lower water–air volatilization fluxes of Σ ICEs PCBs were found over the Pacific Ocean (0.5–30.4 ng/m 2 /d) in 2006–2007 (Zhang & Lohmann, 2010), and the Indian Ocean (0.34–34 ng/m 2 /d) in 2011 (Huang et al., 2014).…”

“…Black dots are the sampling sites in the open oceans. Data sets for the PCB exchange fluxes are derived from Yangtze River Estuary (Guo et al., 2020), East China Sea (this study), Lake Baikal (McConnell et al., 1996), Lake Bourget (Masset et al., 2019), Lake Ontario, Lake Erie, Lake Superior, Lake Michigan and Lake Huron (Hillery et al., 1998), Norwegian Sea (Gioia, Lohmann, et al., 2008), Pacific Ocean (Zhang & Lohmann, 2010), Atlantic Ocean (Gioia, Nizzetto, et al., 2008), Indian Ocean (Huang et al., 2014), Mediterranean Ocean (Berrojalbiz et al., 2014), lake on the Tibetan Plateau (Ren et al., 2017), and Venice lagoon (Manodori et al., 2007).…”
