【摘要】 十年来,中国近海各海域先后开展了污染调查监测,面积达38万平方公里。同时,对沿海污染源进行了调查。本文根据近年来的资料,对中国近海几种主要污染物质的来源和海域的水污染状况进行了分析,认为:(1)河流携带是污染物入海的主要方式;(2)石油是海区最主要的污染物,东海近岸和渤海是油污染最严重的两个海区;(3)中国北部海区的有机污染比南部海区明显;(4)重金属污染仅限于局部近岸和河口海区,范围很小。更多还原

【Abstract】 Last ten years, surveillance and monitoring of pollution have been developedon the offshore of all sea areas of China. The area comes up to 380,000km~2.At the same time the pollution sources have been researched along the coast.According to the existing data, the source of some main pollutants and waterpollution state have been analysed.Conclusions (1) The discharge of the pollution substance carried into sea by river isa chief way. (2) The oil is the main pollutant to the sea. The oil pollution is muchserious near the coast of Bohai Sea and East China Sea. (3) Organic pollution in the north of China seas is much more evidentthan in the south. (4) The heavy metal pollution is only limited in part of the offshore andestuary. The scope is very little.更多还原
