Rapid development and application of nanomaterials and nanotechnology make assessment of their potential health and environmental impacts on humans, non-human biota, and ecosystems imperative. Here we show that pumpkin plants (Cucurbita maxima), grown in an aqueous medium containing magnetite (Fe3O4) nanoparticles, can absorb, translocate, and accumulate the particles in the plant tissues. These results suggest that plants, as an important component of the environmental and ecological systems, need to be included when evaluating the overall fate, transport and exposure pathways of nanoparticles in the environment.
纳米材料和纳米技术的快速发展与应用使得评估它们对人类、非人类生物群和生态系统的潜在健康与环境影响变得势在必行。在此我们表明，在含有磁铁矿（Fe3O4）纳米颗粒的水介质中生长的南瓜植株（南瓜属）能够在植物组织中吸收、转运并积累这些颗粒。这些结果表明，在评估纳米颗粒在环境中的整体归宿、迁移和暴露途径时，作为环境和生态系统重要组成部分的植物需要被纳入考量。
