Widely used nanoparticles enter soybean plants from farm soil
Washington DC (SPX) Feb 14, 2013
Two of the most widely used nanoparticles (NPs) accumulate in soybeans - second only to corn as a key food crop in the United States - in ways previously shown to have the potential to adversely affect the crop yields and nutritional quality, a new study has found. It appears in the journal ACS Nano. Jorge L. Gardea-Torresdey and colleagues cite rapid increases in commercial and industrial uses of NPs, the building blocks of a nanotechnology industry projected to put $1 trillion worth of products ... read more
