Dangers of Iron Nanoparticles The chemical reactivity of a substance is directly proportional to the surface area of a substance. As particles get smaller, the surface area increases exponentially. Because of their small size, iron nanoparticles are extremely reactive (from 10-1000 times more reactive than current iron powder used to purify industrial wastes) and will explode in the presence of air if not suspended in a slurry. The iron nanoparticles used in the purification of industrial waste sites have been shown to be reactive for 4-8 weeks and they have the potential to travel 20m down into the soil where applied because of their

These particles could contaminate ground water and affect soil ecology by invading the members of a food chain (i.e. worms) Although iron has no known toxic affect and is already present rocks, soil, and water, the bioaccumulation of the nanoparticles could pose threats to human health in the future. http://www.futurepundit.com/archives/001641.html Bionanotechnology By Elisabeth Papazoglou – HOLY SHIT A BOOK. http://www.nsf.gov/od/lpa/news/03/pr0394.htm...
