Pesticides play a significant key role in the agriculture sector. In India, there is a sharp increase in pesticides consumption in recent years, leading to severe implications. Due to the rapid use of pesticides, there is residue in the food, which leads to poor effects on human health. Furthermore, the discharge of various pesticides into water bodies from the industries and agricultural activities leads to environmental concerns. Because of their toxicity, persistent nature, and bioaccumulation potential, it is essential to remove pesticides from water. Nanoparticles are tiny particles whose size ranges from 1 to 100 nm. Nanomaterials have a large surface area, a large number of active sites, and high reactivity. Therefore, nanotechnology is a fast, efficient, and economical process. Nanotechnology plays an influential role in the removal of various pesticides from water and wastewater. In recent years, various nanomaterials, such as TiO₂, ZVI, Zn, and rGO (reduced graphene oxide), CNTs (carbon nanotubes), and polymer-supported nanomaterials are widely used for the removal of pesticides from water. In this review, detailed information about various pesticides and their removal with the help of nanocomposites has been discussed.

农药在农业部门中发挥着重要的关键作用。在印度，近年来农药消费量急剧增加，造成了严重影响。由于农药的快速使用，食品中存在残留，对人体健康造成不良影响。此外，工业和农业活动向水体排放各种农药会导致环境问题。由于它们的毒性、持久性和生物积累潜力，必须从水中去除农药。纳米颗粒是尺寸在 1 到 100 nm 之间的微小颗粒。纳米材料具有表面积大、活性位点多、反应活性高等特点。因此，纳米技术是一种快速、高效和经济的过程。纳米技术在去除水和废水中的各种农药方面发挥着重要作用。近年来，各种纳米材料，如 TiO_{如图 2 所示}，ZVI、Zn 和 rGO（还原氧化石墨烯）、CNT（碳纳米管）和聚合物负载的纳米材料被广泛用于去除水中的农药。在这篇综述中，讨论了有关各种杀虫剂及其在纳米复合材料的帮助下去除的详细信息。
