广东沿海地处南海北部大陆架浅海区,深受陆源物质的影响,随着工农业生产的发展,陆地上的污染物源源不断地通过地表径流和大气输送入南海。海洋底质可以反映海洋受污染的历史和现状,因此,了解广东沿海底质中重金属含量及其分布规律,对利用沿海海域,保护水产资源很有必要。 本文引用珠江口海区、粤西海区和粤东海区污染调查的有关资料进行分析探讨。 一、采样布点及分析方法 The coast of Guangdong is located in the shallow sea area of ​​the continental shelf in the northern part of the South China Sea and is deeply affected by terrestrial material. With the development of industrial and agricultural production, pollutants on land continue to flow into the South China Sea through surface runoff and atmospheric transport. Marine sediments can reflect the history and current situation of marine pollution. Therefore, it is necessary to understand the heavy metal content and its distribution in the coastal sediments of Guangdong and to protect the aquatic resources by utilizing the coastal waters. This article quoted the Pearl River Estuary area, western Guangdong and eastern Guangdong pollution investigation of the relevant data for analysis. First, sampling distribution and analysis methods
