The Migration Study of Nanoparticles from Soil to the Leaves of Plants

Abstract

In this work by the UV-vis and TEM analysis were investigated the transport of nanoparticles (Ag and Au) in soil, their migration from seeds to the roots and from roots to the stem and leaves of pea plants. Nanoparticles depending on the types and sizes may diffuse and distribution in soil. The transport of nanoparticles in soil dependance on the structure and soil thickness. According to the results of experiments were identified that nanoparticles may diffuse into the seeds and changes the imbibition (water uptake). Nanoparticles may pass on from seeds to the roots and localization in the xylem and epidermal cells. By the development of seedling nanoparticles may transport from roots to the stem and from stem to the leaves. Nanoparticles may localization in different cells of plant organs and inside of cell mostly in the mitochondria.
