Nanotechnology: are safety concerns real or imagined?
Hundreds of nanotechnology products about to hit shop shelves have not been properly tested for their safety, one of the UK's leading environmental health experts has warned.
However Dr. Gerhard Nohynek, scientific director of worldwide safety evaluation at cosmetic giant L'Oreal, which uses nanotechnology in some of its products, said: "This is a load of baloney. There are products which contain nanoparticles, such as sunscreens, but these have been tested and are known to be safe."
