Greenies now trying to stop nanotechnology

I guess they would like us to give a future industry over to China or some other place not so infested with ratbags

It is microscopically tiny and most agree that it could one day revolutionise medicine, manufacturing, energy production and life in the 21st century. But the ultra-fine particles created for cosmetic, industrial and high-technology uses could prove to be as deadly in future as asbestos is today, according to groups calling for a moratorium on "nanotechnology". The moratorium should stay in place until more is known about the health effects of the new technology and a licensing system is introduced for the thousands of different microscopic nanoparticles being created, the groups say.

The technology involves manipulating and engineering matter at an atomic or molecular level - so extraordinarily small that it can change the physical properties of the particles, developing new products, but also new and unknown hazards. At this scale, the standard measure is a nanometre - one billionth of a metre, or about 1/80,000th the width of human hair. The diameter of DNA, our genetic material, is in the 2.5 nanometre range. At this size, it is possible that particles can enter the bloodstream through the skin barrier, or from the lungs and intestinal tissue.

Even though there are no specific regulations governing it, nanotechnology is already used in areas such as electronics, pharmaceuticals, sunscreens, and optical fibres. Products on the market range from computer displays, self-cleaning windows, paints, varnishes and wrinkle creams. In Australia, government and industry invest about $100 million a year in nanotechnology. About 50 companies use or are researching the technology and the Australian Research Council finances more than 200 nanotechnology projects. The State Government has invested $12 million in Nanotechnology Victoria, a venture between Monash, RMIT and Swinburne universities and CSIRO that aims to commercialise the technology. As well as high-technology applications, nanoparticles are found in the by-products of diesel engines, furnaces and welding.

The director of lobby group GeneEthics, Bob Phelps, says: "Each type of nanoparticle may be as deadly as asbestos so the worker and public health challenge is huge." He wants a national new technology assessment and regulation office created to research the environmental, occupational and public health risks involved. He says 25 per cent of the investment in nanotechnology should be spent on research.

Friends of the Earth estimates that 300,000 Australian workers could be exposed to nanoparticles in the refining and welding fields; a further 33,000 may be exposed through handling various fine powders, mainly in the pharmaceutical and cosmetics industries, and about 700 in universities and R&D companies. Friends of the Earth says a "regulatory vacuum" surrounds nanotechnology. It supports a moratorium on the research, development and manufacture of synthetic nanoparticles until regulations are developed to protect workers, the public and the environment from exposure. "This could prevent huge human and financial costs and waves of expensive compensation claims from injured persons, as has been seen with asbestos," it says in a submission to a Senate committee inquiry."
