With the rapidly increasing demand for and use of engineered nanoparticles (NPs) in agriculture and related sectors, concerns over the risks to agricultural systems and to crop safety have been the focus of a number of investigations. Significant evidence exists for NP accumulation in soils, including potential particle transformation in the rhizosphere and within terrestrial plants, resulting in subsequent uptake by plants that can yield physiological deficits and molecular alterations that directly undermine crop quality and food safety. In this review, we document in vitro and in vivo characterization of NPs in both growth media and biological matrices; discuss NP uptake patterns, biotransformation, and the underlying mechanisms of nanotoxicity; and summarize the environmental implications of the presence of NPs in agricultural ecosystems. A clear understanding of nano-impacts, including the advantages and disadvantages, on crop plants will help to optimize the safe and sustainable application of nanotechnology in agriculture for the purposes of enhanced yield production, disease suppression, and food quality.

食品作物对工程纳米颗粒的吸收:表征,机制和意义。

随着农业和相关部门对工程化纳米颗粒(NPs)的需求和使用的迅速增加,对农业系统和作物安全的风险的关注已成为许多研究的重点。有大量证据表明土壤中NP的积累,包括根际和陆生植物内部潜在的颗粒转化,导致植物随后的吸收,这些吸收可产生生理缺陷和分子变化,直接破坏作物的质量和食品安全。在这篇综述中,我们记录了生长培养基和生物基质中NP的体外和体内表征;讨论NP的吸收模式,生物转化以及纳米毒性的潜在机制;并总结了农业生态系统中NP的存在对环境的影响。
