| 英文摘要 | The occurrence of 15 polycyclic aromatic hydrocarbons (PAHs) for priority control were analyzed in the surface and bottom seawater of the Bohai Sea during June (spring-summer), August (summer), and November (autumn) of 2019. Concentrations, composition, spatial distribution, seasonal variations, and main sources of PAHs were discussed. Results showed that total PAH concentrations (15PAHs) in surface seawater ranged from 10.1 to 67.0 ng/L in June, from 3.20 to 24.2 ng/L in August, and 6.14 to 21.5 ng/L in November, with an average concentration of 34.216.8, 9.754.94, and 16.03.96 ng/L, respectively. PAH concentrations were significantly higher in June than in November and in August. PAHs mainly consisted of low-ring PAH congeners in dissolved phase, and of high-ring PAH congeners in the particulate phase. River input was the primary source of PAHs in the seawater of Bohai Sea. High concentration of PAHs was observed in the coastal area of the Bohai Sea and the Laizhou Bay. In June and November, no noticeable difference was observed for the vertical distribution of PAHs in the entire Bohai Sea. This indicates that the seawater was mixed well from surface to bottom owing to the strong monsoon. However, in the center of the Bohai Sea in August, an elevated level of PAHs was observed on the surface layer, and a low concentration in the bottom layer. This probably relates to the appearance of a cold-water mass and seawater stratification. No seasonal differences in PAH sources were observed, and fossil fuel and biomass burning were the main sources. |
