摘要
农田土壤中的农药污染是威胁农产品安全的重要因素之一。在病虫草害的化学防治过程中,田间施用的农药最终会进入土壤环境并在其中转化积累,导致农田土壤环境污染。农作物能够通过根部吸收将土壤中的农药转运至植物体的各个器官和组织中,造成农产品中的农药残留,影响农产品质量和安全。本文系统地综述了土壤中农药残留进入植物体的途径,指出了可能影响土壤中农药进入植物体的内外因素,着重强调了其对农产品安全存在的潜在威胁,并针对农田土壤污染的治理和此类食品安全问题的防范提出了合理的建议。最后展望了未来研究应该关注的问题和方向。
The pesticide pollution in farmland soil is one of the most important factors threatening the safety of agricultural products.However,during the process of chemical control of diseases,insects and weeds,the applied pesticides might eventually enter the soil environment and accumulated in it,resulting in the pollution of farmland soil.Also,the crops can absorb pesticides from soil by the roots and translocate them to different parts,which leads to the accumulation of pesticide residues in agricultural products and quality and safety problems.This paper systematically summarized the pathways of the pesticide residues from soil to plants,pointed out the internal and external factors affecting the translocation,emphasized the potential threats of this process to the safety of agricultural products,and put forward several reasonable suggestions in view of controlling soil pollution and preventing safety accidents.At the end of this article,the problems and the future direction of research in this field were prospected.
