Accumulation and transfer of polystyrene microplastics in Solanum nigrum seedlings
Microplastic (MP) pollution is lately receiving increasing attention owing to its harmful impact on terrestrial ecosystems. In this microcosm study, we assessed the uptake and transfer of MPs in Solanum nigrum seedlings exposed to 50 mg L(–1) of 0.2-µm polystyrene (PS) beads for 30 d. Confocal laser...

description | Microplastic (MP) pollution is lately receiving increasing attention owing to its harmful impact on terrestrial ecosystems. In this microcosm study, we assessed the uptake and transfer of MPs in Solanum nigrum seedlings exposed to 50 mg L(–1) of 0.2-µm polystyrene (PS) beads for 30 d. Confocal laser scanning micrographs helped detect highly intense red fluorescence signals from PS-MP beads in S. nigrum root compared with the controls. Confocal images revealed that the PS beads were primarily distributed in the epidermis and xylem of roots and vascular systems of stems and leaves. Scanning electron microscopy showed that PS beads were scattered on the cell walls of the root xylem and leaf vascular system. Few PS beads were transferred from roots to stems and leaves via the vascular system following the transpiration stream. In conclusion, our findings showed that PS beads accumulated in S. nigrum roots and were transferred from the roots to the aerial parts. |
