John Watsony and quality of food and water as well as increased pollution in big cities. Therefore some often asked questions are: whether nanotechnology would help to solve or increase some of these problems? Do nanomaterials harm human bodies, animals or plants, may be by inhaling or by contact? Will nanomat
