目前,研究世界大洋(包括洋、海、河口)化学污染的生态学后果和研究防止化学污染对地球生态学影响的措施是一个极为重要的科学技术问题。苏联的研究表明: ——石油和有机氯碳氢化合物等一系列污染物质对海洋的污染具有全球性; ——这些物质在大洋中改变了海洋表面海水的物理化学性质; At present, studying the ecological consequences of chemical pollution in the world’s oceans (including the ocean, sea and estuary) and studying measures to prevent the impact of chemical pollution on the ecology of the earth is an extremely important scientific and technological issue. Research by the Soviet Union shows that: - a series of pollutants such as oil and organochlorine hydrocarbons have a global impact on the pollution of the oceans; - these substances alter the physico-chemical properties of ocean surface seawater in the oceans;
