US scientists have shown that plants can absorb nanoparticles from their environment - meaning that the particles could find their way into the human food chain, the team claims.rnYan Jin and colleagues at the University of Delaware, in Newark, found that pumpkin plants can take up nanoparticles through their roots and that the particles are transported around the plant. The study is part of an effort to assess nanoparticles' environmental and biological fate if they are released into soil or groundwater, says Jin.
