Uptake and Distribution of 14C-Labeled Multi-walled Carbon Nanotubes by Wheat (Triticum aestivum L.)
Uptake of 14C-labeled multi-walled carbon nanotubes (MWCNTs) to wheat seedlings (Triticum aestivum L.) was evaluated. After exposing the plants to MWCNT suspensions for 5 days, the quantity and distribution of MWCNTs accumulated by the seedlings were measured. The total uptake percentage was more than 0.12% in all dosage levels, and a good correlation was found between the MWCNT contents in the root and the initial MWCNT concentration. This shows that MWCNTs can enter the wheat plant and be accumulated in root and shoot, which might in turn further transfer in the terrestrial food chain.
