The ubiquitous problem of pesticide in aquatic environment are receiving worldwide concern as pesticide tends to accumulate in the body of the aquatic organism and sediment soil, posing health risks to the human. Many pesticide formulations had introduced due to the rapid growth in the global pesticide market result from the wide use of pesticides in agricultural and non-agricultural sectors. The occurrence of pesticides in the water body is derived by the runoff from the agricultural field and industrial wastewater. Soluble pesticides were carried away by water molecules especially during the precipitation event by percolating downward into the soil layers and eventually reach surface waters and groundwater. Consequently, it degrades water quality and reduces the supply of clean water for potable water. Long-time exposure to the low concentration of pesticides had resulted in non-carcinogenic health risks. The conventional method of pesticide treatment processes encompasses coagulation-flocculation, adsorption, filtration and sedimentation, which rely on the phase transfer of pollutants. Those methods are often incurred with a relatively high operational cost and may cause secondary pollution such as sludge formation. Advanced oxidation processes (AOPs) are recognized as clean technologies for the treatment of water containing recalcitrant and bio-refractory pollutants such as pesticides. It has been adopted as recent water purification technology because of the thermodynamic viability and broad spectrum of applicability. This work provides a comprehensive review for occurrence of pesticide in the drinking water and its possible treatment.
水生环境中无处不在的农药问题受到了全世界的关注，因为农药往往会在水生生物和底泥中积累，对人类健康构成威胁。由于农业和非农业部门广泛使用农药，全球农药市场迅速增长，许多农药制剂应运而生。水体中农药的出现是由农业领域的径流和工业废水造成的。水溶性农药会被水分子带走，特别是在降水事件中，会向下渗透到土壤层，最终到达地表水和地下水。因此，它会降低水质，减少饮用水的清洁水供应。长时间暴露在低浓度的农药下会导致非致癌健康风险。传统的农药处理工艺包括混凝-絮凝、吸附、过滤和沉淀，这些方法依赖于污染物的相转移。这些方法通常需要较高的运营成本，并且可能会造成二次污染，如污泥形成。高级氧化工艺 (AOPs) 被认为是处理含有难降解和生物难降解污染物（如农药）的水的清洁技术。由于其热力学可行性和广泛的适用性，它已被采用为最近的水净化技术。这项工作为饮用水中农药的存在及其可能的处理提供了全面的综述。
