摘要
海滩粗颗粒沉积物中的重金属污染问题常被忽视,但是日益增强的人类活动造成了海滩沉积物重金属不同程度的污染,对海滩及周边的动植物和人类产生严重的损害,并降低了海滩质量和旅游及生态价值,这一问题受到越来越多人的关注。因此要及时了解海滩重金属污染的程度、范围、生态风险及其检测方法。本文在查阅全球海滩沉积物重金属污染的大量数据基础上,总结了海滩重金属在全球范围内的污染程度及分布特征,阐明了海滩重金属的污染评估结果及生态风险,揭示了海滩重金属的来源及其在沉积物中的扩散规律,并分析了海滩重金属污染的检测方法以及存在的问题。研究结果将对有效治理海滩污染、保护生态环境及健康发展旅游经济提供重要参考。
The problem of heavy metal pollution in coarse sediment on beaches is often overlooked,but the increasing human activities have caused varying degrees of heavy metal pollution in beach sediment.This phenomenon causes serious damage to the flora,fauna,and humans around the beach,and reduces the quality,tourism,and ecological value of the beach.This issue is receiving increasing attention from people.Therefore,it is necessary to timely understand the degree,scope,ecological risks,and detec-tion methods of heavy metal pollution on beaches.This article collects a large amount of data on heavy metal pollution in global beach sediments,summarizes the distribution and degree of heavy metal pollu-tion in beaches on a global scale,elucidates the pollution assessment results and ecological risks of heavy metals in beaches,reveals the sources of heavy metals in beaches and their diffusion patterns in sedi-ments,and analyzes the detection methods and existing problems of heavy metal pollution in beaches.The research results will provide important references for effective control of beach pollution,protection of the ecological environment,and healthy development of tourism economy.
