海洋沉积物中石油类污染物的释放研究

沉积物中石油类污染物的释放过程受到海洋水动力、环境因素、海床沉积物特性及生物扰动等条件的影响，引发的二次污染作用周期长，而且对水体环境、沿海娱乐活动及海洋生物的各项生理活动都会造成影响。为加深对该释放过程的认识，本文阐述了海洋沉积物中石油类污染物的释放机理，重点分析了海床液化失稳对该过程的影响机制，总结了石油类污染物释...

A review of studies on the release of petroleum pollutants from sediments in marine environment

The release process of petroleum pollutants in sediments is influenced by marine hydrodynamics, environmental factors, characteristics of seabed sediments and biological disturbance, etc. The secondary pollution caused by these pollutants has a long cycle and affects the water environment, coastal recreational activities and various physiological activities of marine organisms. In order to deepen the understanding of the release process, this paper summarizes the mechanism of the release of petroleum pollutants in marine sediments, emphatically analyzes the mechanism of the influence of seabed liquefaction instability on the process, and summarizes the dynamic model of the release of petroleum pollutants. Finally, the future research directions and work emphases of petroleum release from sediments are pointed out: to explore the influence of physical and chemical properties of sediments on petroleum release from sediments, to study the effect of wave-induced pore pressure accumulation on this process, and to establish a dynamic model of petroleum release under wave action.
