The uptake, bioaccumulation, biotransformation, and risks of nanomaterials (NMs) for food crops are still not well understood. Very few NMs and plant species have been studied, mainly at the very early growth stages of the plants. Most of the studies, except one with multiwalled carbon nanotubes performed on the model plant Arabidopsis thaliana and another with ZnO nanoparticles (NPs) on ryegrass, reported the effect of NMs on seed germination or 15-day-old seedlings. Very few references describe the biotransformation of NMs in food crops, and the possible transmission of the NMs to the next generation of plants exposed to NMs is unknown. The possible biomagnification of NPs in the food chain is also unknown.
纳米材料（NMs）在食物作物中的摄取、生物积累、生物转化和风险仍未被充分了解。仅有少数 NMs 和植物物种被研究过，主要是在植物非常早期的生长阶段。除了一项在模式植物拟南芥上进行的关于多壁碳纳米管的研究和另一项在黑麦草上进行的关于氧化锌纳米颗粒（NPs）的研究外，大多数研究都报告了 NMs 对种子发芽或 15 天大的幼苗的影响。很少有参考文献描述 NMs 在食物作物中的生物转化，以及暴露于 NMs 的植物的下一代可能会传递 NMs，这一点尚不清楚。纳米颗粒在食物链中可能的生物放大作用也不清楚。
