摘要
土壤砷污染问题是目前环境科学领域的热门研究问题,随着自然环境的演变和人类活动的影响,土壤砷污染问题日趋严峻。土壤砷污染是面向全球化的问题,国内外关于土壤砷污染状况的调查不容乐观。砷是一种危害性大、高毒性的类重金属污染物,其广泛分布于自然界,能以多种价态化合物存在。砷元素不仅会污染环境,还会以食物链为渠道进入人体,从而对人类健康产生威胁。我国土壤深受砷污染危害,土壤砷污染治理已经成为当今迫切需要解决的关键问题。本文就土壤砷污染问题展开论述,分析了土壤砷污染的来源及危害,阐明了目前国内外土壤砷污染的现状,分别从物理修复技术、化学修复技术、生物修复技术3个方面介绍了土壤砷污染问题的主要修复技术,旨在为有效治理土壤砷污染问题提供参考和保护土壤生态环境,并对未来土壤砷污染修复技术的研究进行了展望。
Soil arsenic pollution is a hot research problem in the field of environmental science.With the evolution of natural environment and the influence of human activities,soil arsenic pollution is becoming more and more serious.Soil arsenic pollution is a globalization-oriented problem,and domestic and foreign investigations on the status of soil arsenic pollution are not optimistic.Arsenic is a highly hazardous and toxic heavy metal pollutant that is widely distributed in nature and can exist in various valence compounds.Arsenic not only pollutes the environment,but also enters the human body through the food chain,thus threatening human health.China's soil is deeply harmed by arsenic pollution,and soil arsenic pollution control has become a key issue that urgently needs to be solved today.This article discusses the issue of soil arsenic pollution,analyzes the sources and hazards of soil arsenic pollution,and elucidates the current situation of soil arsenic pollution at home and abroad.This article introduces the main remediation technologies for soil arsenic pollution from three aspects:physical remediation technology,chemical remediation technology,and biological remediation technology.The aim is to provide reference for effective management of soil arsenic pollution and protect the soil ecological environment,and to prospect future research on remediation technologies for soil arsenic pollution.
