除草剂对环境污染与风险评价的研究进展

为了保障农业生产,在田间耕种过程中,各类除草剂被广泛使用。除草剂的除草效果显著,施用后会部分残留在土壤或飘浮在大气中,对环境造成污染。介绍了除草剂对环境造成的污染以及针对污染问题做出的风险评价的研究进展。重点阐述了除草剂对水体、土壤、大气等造成的危害,提出合理施用除草剂,提高除草剂最大利用率,有效降低环境污染程度,促进我国农业实现可持续发展。

In order to ensure agricultural production,various herbicides are widely used in the field cultivation process.Although the herbicide has a significant weeding effect,it will partially remain in the soil or float in the atmosphere after application and cause environmental pollution.For a long time,the environmental pollution of herbicides has attracted much attention.In response to this problem,this article focuses on the environmental pollution caused by herbicides so far,as well as the research progress of risk assessments made for pollution problems.It focuses on the harm caused by herbicides to water bodies,soil,atmosphere,etc.,it is proposed to rationally apply herbicides to increase the maximum utilization rate of herbicides,effectively reduce the degree of environmental pollution,and promote the sustainable development of agriculture in our country.
