纳米技术使农业得到广泛的发展。然而，由于它仍处于相对早期的发展阶段，潜在的风险仍然不清楚。本文首次揭示了多壁碳纳米管（MWCNTs）对芥菜（Brassica juncea）中污染物积累/净化行为的影响以及MWCNTs在完整成熟芥菜植株中的渗透性和转运性。使用anin vivosampling技术，动力学积累/净化过程中的几种污染物暴露于多壁碳纳米管的芥菜计划进行了跟踪和增强的污染物积累在活的植物中进行了观察。同时，我们观察到多壁碳纳米管渗透到完整的活植物（三个月大）的根部，然后在蒸腾蒸汽的作用下被运输到上部器官。本研究表明，多壁碳纳米管可以作为污染物的载体，并运输到作物的可食用部分。
Nanotechnology permits broad advances in agriculture. However, as it is still at a relatively early stage of development, the potential risks remain unclear. Herein, for the first time, we reveal the following: 1) the impact of multi-walled carbon nanotubes (MWCNTs) on the accumulation/depuration behaviors of contaminants in crop, mustard (Brassica juncea) and 2) the permeability and transportability of MWCNTs in intact mature mustard plants. Using anin vivosampling technique, the kinetic accumulation/depuration processes of several contaminants in mustard plans exposed to MWCNTs were traced and an enhancement of contaminant accumulation in living plants was observed. Meanwhile, we observed that the MWCNTs permeated into the roots of intact living plants (three months old) and were then transported to the upper organs under the force of transpiration steam. This study demonstrated that MWCNTs can act as contaminant carriers and be transported to the edible parts of crops.
