The advent of industrialization has led to the discovery of a wide range of chemicals designed for multiple uses including plant protection. However, after use, most of the chemicals and their derivatives end up in soil and water, interacting with living organisms. Plants, which are primary producers, are intentionally or unintentionally exposed to several chemicals, serving as a vehicle for the transfer of products into the food chain. Although the exposure of pesticides towards plants has been witnessed over a long time in agricultural production, other chemicals have attracted attention very recently. In this review, we carried out a comprehensive overview of the plant uptake capacity of various contaminants of emerging concern (CEC) in soil, such as pesticides, polycyclic aromatic hydrocarbons, perfluorinated compounds, pharmaceutical and personal care products, and engineered nanomaterials. The uptake pathways and overall impacts of these chemicals are highlighted. According to the literature, bioaccumulation of CEC in the root part is higher than in aerial parts. Furthermore, various factors such as plant species, pollutant type, and microbial interactions influence the overall uptake. Lastly, environmental factors such as soil erosion and temperature can also affect the CEC bioavailability towards plants.
工业化的发展带来了广泛的化学物质的发现,这些化学物质被设计用于多种用途,包括植物保护。然而,在使用后,大多数化学物质及其衍生物最终会进入土壤和水中,并与生物体相互作用。植物作为初级生产者,会有意或无意地暴露于多种化学物质之下,成为将产品转移到食物链中的载体。尽管在农业生产中已经观察到了很长时间的农药对植物的暴露,但其他化学物质最近才引起了关注。在这篇综述中,我们全面概述了土壤中各种新兴关注污染物(CEC)的植物摄取能力,如农药、多环芳烃、全氟化合物、药物和个人护理产品以及工程纳米材料。强调了这些化学物质的摄取途径和整体影响。根据文献,CEC 在根部的生物积累量高于在地上部分。此外,植物种类、污染物类型和微生物相互作用等各种因素都会影响整体摄取。最后,土壤侵蚀和温度等环境因素也会影响 CEC 对植物的生物利用度。
