Urgent calls issued for more health research into nanoparticle technology

While there’s little doubting the groundbreaking benefits associated with advances in the world of nanotechnology, concerned experts are this week calling for more in-depth research to be conducted into the potential health ramifications that using “nanomaterials” could have.

Although there is currently no evidence to suggest the use of nanotechnology in mainstream consumer products is in any way detrimental to human health or the planet in general, the Royal Commission on Environmental Pollution claims some nanomaterials could carry damaging effects.In terms of existing spread, such miniscule nanoparticles are already being used in some 600 different consumer products around the planet, ranging from clothing through to cosmetics. And a further 1,500 items have already been patented ahead of release, reports The Press Association.According to Commission chairman Sir John Lawton, a “major gap” exists between the evolving mainstream acceptance of nanotechnology in consumer products and the supporting scientific research into its related safety.“Would we know if nanomaterials were causing harm? No we wouldn’t,” said Sir John. “There’s no evidence of harm, but a lot of that is because of a lack of evidence.”One such material that has raised an eyebrow is nanosilver, which can be found in socks and sports apparel and is included in the manufacturing process to help kill off bacteria and reduce resulting sweat odour.In the case of nanosilver, which does not degrade and is said to be more toxic than bleach, experts are seeking the application of more research to gauge whether the material is being released into the water system during washing and could possibly damage the sewage treatment process. The Daily Mail reports that Sir John Lawton has said he will not permit his family to wear any clothing imbued with nanotechnology. However, that may become increasing difficult considering a recent report by consumer group Which? revealed that many product manufacturers are not declaring the use of nanoparticles. While the Royal Commission is keen on seeing more research, its latest report on the technology falls short of calling for a ban and even lauds the significant benefits already associated with nanomaterials.

There is a real concern that nano-particles will have a disruptive effect on cellular structure. In my opinion, nano materials should not be used until they have passed stringent toxicity testing. It's a good thing that the technology is being scrutinized more carefully.
