Differentially charged nanoplastics demonstrate distinct accumulation in Arabidopsis thaliana

nature.com
  • Study shows that Arabis (rockcress) can absorb and transport nanoplastics smaller than 200nm.
  • The plant absorbs differently charged nanoplastics in different ways, negatively charged ones being the most internalized.
  • This process can damage roots, and influence how plants transport water and nutrients, making the above-ground parts of the plant smaller.
  • Other plants, especially root crops like carrots and turnips, should be studied for the same process, as they are the foundation of many food chains.
  • Further studies will have to confirm if accumulation of nanoplastics will lead to worse crop yields, worse food quality, or even make common foods unsafe to eat.
