水土环境介质中阿特拉津修复过程研究进展
A Review on Remediation of Atrazine in Soil and Water Systems
-
摘要: 除草剂阿特拉津农用后的残留物会随地表径流或地下渗漏作用进入江河湖泊等自然水体,由于阿特拉津的环境内分泌干扰作用,其会造成水资源污染和水生态失衡。根据阿特拉津的生产和使用状况,将阿特拉津的污染对象分为土壤、市政污水、河流湖泊等地表水和地下水系统模块,分别阐述了这几种环境介质中阿特拉津的物理、化学和生物修复技术以及阿特拉津在修复过程中的变化特点,介绍了土壤在淋溶过程中阿特拉津的固定手段和今后污染水体中阿特拉津修复的研究重点。Abstract: Atrazine is a herbicide discharged mostly from agricultural to aquatic ecosystems via surface runoff or underground leakage. The endocrine disrupting actions of atrazine represent a potentially serious threat to aquatic ecosystems. However, there is little research on the physical, chemical and biological techniques that can be applied for atrazine remediation. This paper reviews the problems, challenges and opportunities/strategies of atrazine pollution and remediation. From the perspectives of atrazine production and use, the targets of atrazine pollution can be classified into vadose soil, municipal sewage, surface water and groundwater systems. These ecosystems and application of remediation techniques impose challenges that are often different from that of common soil remediation technologies. The method to immobilize atrazine in the vadose soil system has been discussed, focusing on their limitations and recent efforts to correct drawbacks. The change of atrazine forms in the remediation process, the key research areas of atrazine remediation in water body and the strategies and opportunities for future work have also been reviewed.
