	abstract = {On the basis of the application of compound-specific radiocarbon analysis (CSRA) and air{\textendash}water exchange models, the contributions of fossil fuel and biomass burning derived polycyclic aromatic hydrocarbons (PAHs) as well as their air{\textendash}water transport were elucidated. The results showed that fossil fuel-derived PAHs (an average contribution of 89\%) presented the net volatilization process at the air{\textendash}water interface of the Taiwan Strait in summer. Net volatile fluxes of the dominant fluorene and phenanthrene (>58\% of the total PAHs) were 27 {\textpm} 2.8 μg m{\textendash}2 day{\textendash}1, significantly higher than the dry deposition fluxes (average 0.43 μg m{\textendash}2 day{\textendash}1). The Δ14C contents of selected PAHs (fluorene, phenanthrene plus anthracene, fluoranthene, and pyrene) determined by CSRA in the dissolved seawater ranged from -997 {\textpm} 4{\textperthousand} to -873 {\textpm} 6{\textperthousand}, indicating that 89{\textendash}100\% (95 {\textpm} 4\%) of PAHs were supplied by fossil fuels. The South China Sea warm current originating from the southwest China in summer (98\%) and the Min-Zhe coastal current originating from the north China in winter (97\%) input more fossil fuel PAHs than the Jiulong River estuary (90\%) and Xiamen harbor water (93\%). The more radioactive decayed 14C of fluoranthene (a 4-ring PAH) than that of phenanthrene and anthracene (3-ring PAHs) represented a greater fossil fuel contribution to the former in dissolved seawater.},
