104 products on shelves already contain toxic 'grey goo' by stealth, say Friends of the Earth

Abstract:
Potentially toxic chemicals are being incorporated into food, packaging, health supplements and other products by stealth, it is claimed.

Manufacturers boast that nanoparticles can deliver drugs or vitamins more effectively, kill harmful bugs in food or create self-cleaning windows.

But scientists, consumer groups and green campaigners fear the technology is being introduced into the diet, body and environment without proper safety checks.

Nanoparticles are 80,000 times thinner than a human hair - so small they can cross membranes protecting the brain or a baby in the womb.

Critics say it is not known how such tiny particles will interact with the body and organs in the long term, whether they are toxic or how long they will persist in the body.
