作者（2019）在《Distribution and Sources of Polycyclic Aromatic Hydrocarbons(PAHs) in Meizhou Bay Sewage Outfall and the Surrounding Ocean Area》一文中研究指出：To further clarify the distribution mechanism of polycyclic aromatic hydrocarbons( PAHs) which cause damage to human and ecosystem health,the differences between 15 kinds of PAHs in Meizhou Bay coastal zones in terms of the concentration,spatial distribution and sources,especially the ocean area around drainage outlets of sewage treatment plants,were fully investigated. The results indicated that the total concentration of 15 kinds of PAHs at each sampling station ranged from 27. 2 to 774. 2 ng/L. PAHs in Meizhou Bay coastal zones decreased as follows: 4-ring >3-ring > 5-ring > 6-ring. As for the ∑PAHs,the concentration increased from the reference ocean area,affected ocean area to the mixed ocean area. Furthermore,the concentration of PAHs in the bottom area was obviously larger than that in the surface layer,indicating that the concentration of PAHs with various rings varied significantly in different ocean areas. The concentration of ∑PAHs had no significant correlation with water quality parameters such as temperature,salinity,p H and so on. In addition,PAHs in the mixed ocean area derived from fossil fuel,while PAHs in the affected ocean area and reference ocean area were mainly from fossil fuel and oil.
Abstract
To further clarify the distribution mechanism of polycyclic aromatic hydrocarbons( PAHs) which cause damage to human and ecosystem health,the differences between 15 kinds of PAHs in Meizhou Bay coastal zones in terms of the concentration,spatial distribution and sources,especially the ocean area around drainage outlets of sewage treatment plants,were fully investigated. The results indicated that the total concentration of 15 kinds of PAHs at each sampling station ranged from 27. 2 to 774. 2 ng/L. PAHs in Meizhou Bay coastal zones decreased as follows: 4-ring >3-ring > 5-ring > 6-ring. As for the ∑PAHs,the concentration increased from the reference ocean area,affected ocean area to the mixed ocean area. Furthermore,the concentration of PAHs in the bottom area was obviously larger than that in the surface layer,indicating that the concentration of PAHs with various rings varied significantly in different ocean areas. The concentration of ∑PAHs had no significant correlation with water quality parameters such as temperature,salinity,p H and so on. In addition,PAHs in the mixed ocean area derived from fossil fuel,while PAHs in the affected ocean area and reference ocean area were mainly from fossil fuel and oil.
