草甘膦对环境的影响研究进展

Research Progress on Environmental Impact of Glyphosate

随着现代农业的发展,农药的需求不断增加。草甘膦作为一种除草剂,被广泛应用于农田、果树,草甘膦的大量使用在提高单位面积产量的同时也对环境也带来了潜在的风险。该文综合国内外文献,从草甘膦对土壤环境、水生生物、牲畜以及人体的影响方面阐述了草甘膦对环境的影响。通过综合分析,草甘膦使土壤有盐碱化趋势,对土壤微生物、水体生物一般为低毒,草甘膦的不合理使用能够使牲畜和人中毒甚至死亡。在此基础上,倡导规范使用草甘膦,并对修复土壤污染进行展望,为草甘膦的合理选用提供参考。

With the development of modern agriculture, the demand for pesticide is increasing.Glyphosate is widely used to increase the yield per unit area in farmland, fruit trees, as a herbicide, but the widespread use of glyphosate also poses a potential risk to the environment.In this paper, the effects of glyphosate on the environment were discussed from the aspects of soil environment, aquatic organisms, livestock and human body.Through comprehensive analysis, glyphosate has the tendency of salinization of soil, glyphosate has low toxicity to soil microbe and water body generally, and the unreasonable use of glyphosate can cause livestock and humans to poison or even die.On the basis of this, it is necessary to standardize the use of glyphosate, and this paper also prospected the future research of restoring contaminated soils.The analysis of this paper can provide reference for the rational selection of glyphosate
