EXCERPTS: Our consumer products, such as food, cosmetics and clothes, might be filled with nanomaterials - unbeknownst to us. [...] Nanotechnology is appearing everywhere, to change our daily lives. ... Yet, nanomaterials and their use in consumer products is far from unproblematic. A new study published in Nature Communications sheds light on whether they are harmful and what happens to them when they enter an organism...
[...] "We found that that nanomaterials bind strongly to microorganisms, which are a source of food for other organisms, and this is the way they can enter our food chain. Once inside an organism, nanomaterials can change their shape and size and turn into a more dangerous material that can easily penetrate cells and spread to other organs. When looking at different organs of an organism, we found that nanomaterials tend to accumulate especially in the brain," lead author Dr Fazel A. Monikh from the University of Eastern Finland says.
According to the researchers, nanomaterials are also difficult to measure: their amount in an organism cannot be measured only by using their mass, which is the standard method for measuring other chemicals for regulations. [...] "It could be that you are already using nanomaterials in your food, clothes, cosmetic products, etc., but you still don't see any mention of them in the ingredient list. Why? Because they are still unregulated and because they are so small that we simply can't measure them once they're in your products," Dr Fazel A. Monikh says... (MORE - details)
