Nanotech and Nanotox

From the spring issue of Science in Society:
    Another area where science and technology have gone way ahead of safety considerations is nanotechnology, in particular, nanoparticles and nanotubes.

    The science is fascinating, and the possibilities enormous, but that's precisely why it raises a host of new safety concerns. It seems that all kinds of substances acquire entirely new properties when shrunk to the nanoscale (about a billionth of a metre). They become super-efficient catalysts, they concentrate light energy enormously, acquire new electrical properties, and so on.

    But the first evidence of the hazards has already emerged. Nanotubes could be worse than asbestos, and both nanotube and other nanoparticles can accumulate in organs and tissues.

    Fortunately, at least some scientists involved in developing the technology are much more willing to consider and discuss the safety concerns openly and engage in real dialogue with the public; in contrast to those scientists involved in exploiting GM. More

Names like Love Canal, Chernobyl, and the Exxon Valdez have come to symbolize our anxiety over toxic substances in the environment.
