摘　　要：为保障渤海海域的污染物控制和生态环境保护,文章基于已有监测数据,分析渤海海域表层沉积物中多环芳烃(PAHs、LPAHs、HPAHs和CPAHs)的分布、来源及其与沿岸陆地的相关性。研究结果表明:PAHs、LPAHs、HPAHs和CPAHs含量最高的海湾分别为莱州湾、渤海湾、辽东湾和渤海湾,3个海湾均以LPAHs为主;PAHs及其各类组成的来源主要包括入海河流携带的陆源污染物,海流输送并沉积的泄漏原油以及港口、城市和工业基地的排放污水;PAHs的分布受沿岸土地开发利用以及工业和城镇建设等人类活动影响较大,且沿岸土壤中的PAHs对海洋环境造成破坏。In order to protect the pollution control and ecological environment in the Bohai Sea,based on the existing monitoring data,the distribution and sources of polycyclic aromatic hydrocarbons (PAHs,LPAHs,HPAHs and CPAHs) in surface sediments of the Bohai Sea and their correlation with coastal land were analyzed.The results show that the bays with the highest contents of PAHs,LPAHs,HPAHs and CPAHs are Laizhou Bay,Bohai Bay,Liaodong Bay and Bohai Bay respectively,and their LPAHs are the main components.The sources of PAHs and their various components mainly include land-based pollutants carried by rivers entering the sea,spilled crude oil transported and deposited by currents,and sewage discharged from ports,cities and industries.The distribution of PAHs is greatly influenced by human activities such as land development along the coast and industrial and urban construction,and the PAHs in the coastal soil cause damage to the marine environment.
