More Flack on Nanomaterial

(such as nanosilver, etc) From Gizmorama! “The Cutting Edge of Science Fact and Science Possibilities” Nanomaterials may pose health risk Minuscule nanoparticles added to consumer productsincreasingly may be swarming through the body andthreatening organs like the liver, U.S. scientistsfear. “The smaller a particle, the further it cantravel through tissue, along airways or in bloodvessels,” Dr. Adnan Nasir, a clinical assistantprofessor of dermatology at the University of NorthCarolina at Chapel Hill, told The New York Times.“Especially if the nanoparticles are indestructibleand accumulate and are not metabolized, if you ac-cumulate them in the organs, the organs could fail,”he said. Even when made of inert elements, nano-materials take on unique properties, compared withtheir larger counterparts, due to their small

sizeand large surface area, research suggests. Animalstudies indicate nanoparticles can penetrate cellsand tissues, move through the body and brain andcause biochemical damage. They have also been linkedto testicular cancer and cardiovascular system damageand may pose an environmental hazard, studies suggest.Their use in lotions and creams — particularly inmineral sunscreens — has drawn the most criticalattention, the Times said. Consumer Reports magazinecommissioned a study that found mineral nanoparticlesin five sunscreens, even though four of the companiesdenied using them. A separate study by the U.S.Commerce Department’s National Institute of Standardsand Technology found stoves and toaster ovens emitultrafine particles of 2 to 30 nanometers.
