类金属砷在环境介质中的存在及研究进展
|
Abstract:
类金属砷在环境介质中的迁移、转化是环境科学领域中的一项重要研究课题。本文讨论了砷在土壤、水体、沉积物等环境介质中的存在、植物的富集和超富集作用及其对植物的毒害作用和解毒机制，同时也总结了目前存在的主要问题及未来的研究方向，可为环境介质中砷修复技术的研发奠定一定基础。
The migration and transformation of metal-like arsenic in environmental media is an important research topic. This paper discusses the existence of arsenic in soil, water, sediment and other environmental media, the enrichment and hyperaccumulation of plants and their toxic effects and detoxification mechanisms on plants. At the same time, the main problems and future research directions are summarized, which can lay a foundation for the research and development of arsenic remediation technology in environmental media.
