X-rays reveal uptake of nanoparticles by soya bean crops (2013, city, plants)

Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analysed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant tissue. The results contribute to the controversial debate on plant toxicity of nanoparticles and whether engineered nanoparticles can enter into the food chain. The study was published on 6 February 2013 in the journal ACS Nano.

Thanks for the link, it will be interesting to see what else they find that has already spread into the biosphere.
