海洋溢油的风化过程及其对环境的影响

随着沿海和海上油田的大规模开发，溢油事故屡有发生。据估计，我国海洋年均溢油量约为２万ｔ，对海洋环境构成了严重的危害，成为海洋环境中的主要污染源。根据近年来对海洋溢油污染的研究，详细介绍溢油进入海洋环境的扩散、挥发、溶解、分散及乳化等过程，并进而阐述了对海洋环境的影响。

Efflorescence of ocean oil spill and its influence on environment

Oil spill accident occurs frequently along with the large scale development of the offshore and ocean oil fields. It has been estimated that the average amount of yearly oil spill is about 20000 t in Chinese ocean which causes serious damage to ocean environment and becomes the major pollutant source in ocean environment. On the basis of research of ocean oil spill pollution in recent years the paper introduces in detail the diffusion, volatilization, dissolution, dispersion and emulsification of oil spill entering into ocean environment and illustrates their influence on ocean environment.
