Thank you Marshall, for your review. There is also the concern with the dose, while a certain dose maybe very harmful for a foetus, it may be completely non-harmful for a being with larger size, even if the dose is proportional to the size. Not every compound operate proportional to the size of the individual.
However, do you have any reference to the claim that toxicity is from the nitrate ion and not the other types of silver you mentions? /André 2014-12-17 20:03 GMT+01:00 Marshall <mdud...@king-cart.com>: > > There are several things which make me question this study. > > First it is In Vitro, which does not necessarily correspond to in vivo > application. > > Second this was done with a growing culture.
