Compared to other regions, PAHs deposition fluxes of the north Yellow Sea were higher slightly. For example, in New Jersey, annual average PAH total deposition fluxes ranged from 1479 to 20000 ng/(m2 d). The results may be due to the following factors: 1) more coal, oil and wood were combusted due to a large number of population and rapid economic development; 2) low combustion efficiency of fossil fuels; 3) more total suspended particulate in the atmosphere. PAHs Based on the findings of the study, some suggestions for management to reduce the emissions of the target pollutants into marine atmosphere are presented as follows: Suggestions for management For nutrients: ? Reduce the use amounts and improve the efficiency of fertilizer in agriculture, and prevent the loss of fertilizer; ? Cut the consumption and improve the combustion efficiency of fossil fuels; ? Treatment the municipal wastewater and animal waste properly; For heavy metals Cut the emission of the industrial dust and vehicle exhaust; Control the total suspended particles of the region; Cut the consumption of coal and control the emission of industrial waste gas; For PAHs Cut the consumption and improve the combustion efficiency of fossil fuels; Abate the incomplete combustion of waste; Reduce the discharge of vehicle exhaust; Reduce the combustion of wood in rural areas; Suggestions for management Thanks!谢 谢！ * YAO Ziwei (姚子伟) WANG Zhen (王震) National Marine Environmental Monitoring Center 国家海洋环境监测中心 Feb. 24, 2010 Xiamen, China Second Yellow Sea Regional Science Conference Atmospheric deposition of Chemicals Atmospheric deposition is an important way of some chemicals into the marine.
