摘要:

阿特拉津作为除草剂大面积使用,在提高作物产量的同时,对土壤、地下水和江河湖泊等环境造成了污染。虽然阿特拉津的毒性较低,但其易溶于水、难降解、残留较大,影响作物产量,牵制中国农业的可持续发展。文章对阿特拉津残留量过大时对当地动植物造成的危害,对生态环境产生的威胁,以及对人类健康产生的影响展开综述。报告了阿特拉津的吸附机理与残留原因,阐述了其对动植物产生的影响,将现有的阿特拉津降解方式进行比较和分析,并对阿特拉津降解的未来趋势进行讨论和展望。为解决生物修复技术周期长等问题,结合不同降解方式提出了建设性的意见和建议。将物理修复技术、生物修复技术、化学修复技术相结合,可以找出对阿特拉津残留降解效果最好、有利于当今可持续发展理念的修复技术。

Abstract:

Atrazine, as a herbicide, can cause pollution to soil, groundwater, rivers and lakes while increase crop yield. Although atrazine is less toxic, it affects crop yield and constrains the development of sustainable agriculture in China because it is soluble in water, difficult to degrade and has more residues. This paper summarized the hazards to local flora and fauna caused by excessive atrazine residues, the threat to the ecological environment, and the impact on human health. The adsorption mechanism and residual causes of atrazine were reported, the effects on plants and animals were described. The existing atrazine degradation methods were compared and analyzed, and the future trends of atrazine degradation research were discussed. To solve the problems of long cycle of bioremediation technology, constructive suggestions were put forward in combination with different degradation methods. By combining physical repair technology, bioremediation technology and chemical repair technology, we aim to find out the repair technology that can degrade atrazine residues best and be conducive to the sustainable development.

Key words: herbicide, atrazine, degradation, residue, bioremediation, adsorption characteristics
