早在1975年以前,苏联就对世界大洋海水的化学污染进行过大量的调查研究,结果表明:1.世界大洋海水的石油烃类(包括石油、石油产品及其裂解产物等,简称为PHC)污染呈行星状分布;2.海洋环流对PHC的迁移和扩散起重要作用,3.海水的化学污染对海洋的初级生产力有一定的影响。然而,由于缺乏必要的观测,测定的方法和技术手段,未能
As early as 1975, the Soviet Union conducted extensive investigations into the chemical pollution of the world’s oceans and seas. The results show that: 1. The petroleum hydrocarbons (including petroleum, petroleum products and their pyrolysis products, etc., referred to as PHC for short) in the world’s oceans and oceans, The pollution is in a star-shaped distribution. 2. The ocean circulation plays an important role in the migration and diffusion of PHC. 3. The chemical pollution of seawater has a certain impact on the primary productivity of the ocean. However, due to a lack of necessary observations, methods of determination and technical means failed
