英文摘要	PAHs were analyzed in samples of atmospheric aerosols and suspended matter in seawater collected in the Sea of Japan, Sea of Okhotsk and the North-Western Pacific in June–July 2012. The concentrations of Σ(15) PAHs in the suspended matter of seawater ranged between 1984.7 pg/L to 30260.3 pg/L. The concentration of Σ(14) PAHs in marine aerosols ranged from 17.09 pg/m3 on June 19–22, 2012 in the northern part of the Sea of Japan, the La Perouse Strait to 142.47 pg/m3 on June 25–28, 2012 near middle Kuril Islands. The results of diagnostic ratios analysis indicate that the primary sources of PAH are pyrogenic. This paper discusses the main anthropogenic (coal-fired power plants and population) and natural sources (wildfires) of PAHs and their effect on the concentration of these compounds in the marine air and suspended matter of seawater. Long-range atmospheric transport of PAHs from the continent to the ocean is shown using HYSPLIT backward trajectories. Active fire products (MODIS and VIIRS) data were used to build a regression model. The model as a whole explains 58% and 75% of the Σ 5-ring PAHs and BaP variations in seawater in June–July 2012, respectively. The analysis shows that anthropogenic sources were not a significant contribution factor for PAHs in the seawater at the Sea of Japan during this period. © 2019 Elsevier Ltd
