Nanofibers can pose health risks
Tiny fibers produced using nanotechnology, can be dangerous to humans. Some of them are structurally similar to asbestos fibers and can cause serious health problems, reports BBC, referring to an article published in the journal Toxicology Sciences.
Studies in mice have shown that the penetration of these nanoparticles in the lungs can be cause of various types of cancer, such as mesothelioma. p>
Silver nanowires of various lengths were introduced into the lungs of mice. Smaller particles are removed from the lungs. However, those that were more than five microns (0.005 mm), usually stuck in the lungs of rodents, causing inflammation.
"We knew that the long fibers, in contrast to the short, can cause tumors, but did not know what should be the length at which it occurs, "- says Professor Ken Donaldson, University of Edinburgh. p>
According to him, todays discovery will draft guidelines for manufacturers that will protect people from the risk of fatal diseases. p>
