New Update
More research needs to be conducted,
they say...
Summary of the report:
- New laws are needed to ensure that vanishingly small particles made by the
nanotechnology industry do not pose a threat to humans or the environment,
experts said yesterday. - A government-backed report into nanotechnology from the Royal Academy of
Engineering and the Royal Society, Britain's most prestigious scientific
body, found that while nanotechnology is expected to bring about significant
advances in healthcare, transport and electronics, nanoparticles could be a
cause for concern. - Ann Dowling, the Cambridge University professor who chaired the group
behind the report, said: "Where particles are concerned, size really
does matter. - Nanotechnology, which describes the manufacture of devices and materials
measuring billionths of a metre across, is already used to make nanoparticles
for sunscreens and cosmetics. - In sunscreens, nanoparticles are used because they absorb and reflect UV
rays while appearing transparent to the naked eye. - Concerns surround nanoparticles because they may be inhaled or absorbed
through the skin with unforeseen health consequences. - The report recommends that because they can behave so differently from
known materials, nanoparticles, often defined as particles measuring less
than 100 billionths of a metre wide, and nanotubes, sheets of molecules
wrapped into tiny tubes, should be treated as new substances under European
and UK safety legislation. - To address the lack of understanding of the potential threats of
nanoparticles, Prof Dowling called for the government to fund £6m of
research into their toxicity and how they may build up in bodies and the
environment. - "Unless a meaningful debate gets under way soon, nanotechnology has
the potential to turn into the next GM, - with scientists forced to defend themselves against an anti-science
backlash.
