Environmentalists are worried about the possible risk associated with Nanosilver

30 October 2009

Nanosilver is being widely used as antibacterial and odor-fighting properties in many consumer durable products used by millions of people across globe. Scientists and environmentalists are suggesting having a closer look on the health and environmental aspects of the nanosilver. Off late we have seen many products such as socks, bandages etc. contains nanosilver, which can be washed during laundering operation.

Research from Arizona State suggests that these silver nanoparticles can travel through the wastewater treatment system and can reach the aquatics, where these nanoparticles can have adverse effect on aquatic organisms living in the water. Researchers have first time investigated such release of silver from the clothing products. Paul Westerhoff and Troy M. Benn will be delivering their report at 235th American Chemical Society meeting.

These researchers took six pairs of shocks of various brands of nanosilver-impregnated socks and soaked them in distilled water for one hour. After one hour, the water was tested for nanoparticle and ionic forms of silver. Researchers found that a few socks released silver at few washing, however some didn’t released silver even after several washings.

People at large are not aware about the ingredients present in the consumer products they buy. Researchers further suggest that unlike food labeling, clothes containing silver nanomaterials should also be labeled so that the users can identify the ingredients present in the product they are buying and their possible threat to environment and humans.

    hye,
    i am a keen reader of developments over nanotechnology,if possible could you please provide me with some more information about hazards of this technology
