纳米材料技术的负面影响

纳米技术越来越受到人们的重视,但由研究和报道发现,纳米材料的前景不容乐观.1985年发现巴克球,近来研究人员发现它对鱼的大脑可以产生大范围的破坏,这也是首次找到纳米微粒可能给水生物种造成毒副作用的证据.介绍了纳米微粒对生物及人类健康、环境和军事的影响,以及其他方面的危害,建议及早关注纳米技术的负面影响,并采取四个方面的措施,从源头上控制、阻止不适当的使用,以免引起灾难性的负效应.

Attention to negative effect of nanotechnology

Nanotechnology has got more and more public attentions for its applications in a variety of fields. At the same time, however, researches also have revealed that even more attention should be paid for the negative aspects of the technology since the first report on massive fish brain damage by Barker's ball in 1985. These negative aspects include lung infection by nanoparticles, brain damage and vascular disease induced by nanoparticles taken from lung. Nanoaprticles can also cause serious environment pollution, and even more dangerously it can be used as weapons of mass destruction. Suggestion calls for more researches on the potential negative aspects of nanotechnology. And we should take four measures right now, prevent inappropriate using from source, so as not to cause calamitous negative effects.
