纳米,已经越来越多地进入到我们的生活中,各种纳米涂料、纳米服装、纳米化妆品、纳米电池等,似乎我们身边的所有东西都可以被“纳米”。但近来研究发现,涂料所含纳米微粒可导致人类发生严重肺纤维化,甚至死亡。中国科学院一位不愿透露姓名的纳米专家说:“大部分的纳米物质有一个特性就是尺寸越小,毒性越大。因为尺寸越小,它的表面积越大,反应活性也就越高,进入生物体后跟别的物质反应的可能性就越大。” Nano, more and more into our lives, a variety of nano-coatings, nano-clothing, nano-cosmetics, nano-batteries, etc., it seems that everything around us can be “nano ”. However, recent studies have found that nanoparticles containing paint can lead to severe pulmonary fibrosis in humans, and even death. A Chinese scientist at the Chinese Academy of Sciences, who asked not to be named, said: “Most of the nanomaterials have the property of smaller size and greater toxicity, because the smaller the size, the larger the surface area and the higher the reactivity, The more likely it is to enter the organism and react with other substances. ”"
