Better testing urged for nano materials
There is an urgent need for more extensive testing and control of the nanotechnology materials used in manufacturing, an advisory body has warned.
In its latest study on novel materials, the Royal Comm-ission on Environmental Pollution found that the “pace at which new nanomaterials are being developed is beyond the capacity of existing testing and regulatory arrangements to control the potential environmental impacts adequately”.
Carbon nanofibres have been added to car body panels to make them stronger, while cosmetic companies have used titanium dioxide nanoparticles in suncreams.
Sir John Lawton, chairman of the commission, said there was an urgent need for more research and testing.
“The rate of innovation in this sector far outstrips our capacity to respond to the risks,” he added.
Lawton said nanomaterials should be covered by the controversial European Union Reach legislation on chemicals. However, the commission said there was no need for a “blanket ban” on nanomaterials.
Philip Greenish, chief executive of the Royal Academy of Engineering, said: “The commission is correct to dismiss calls for a moratorium on the development of nanotechnology-enhanced products.
“It is not in the interests of any manufacturer to produce and sell products that may cause harm and the vast majority of companies using nanotechnologies act responsibly.
“Current regulatory systems and commercial pressures, especially for cosmetics, make it difficult for manufacturers to be entirely transparent about how their products work and the research they have done to ensure their safety.
“Consequently, a wholesale review of the current regulatory systems is needed to allow more openness without compromising commercial confidentialities.”
