In the book you have written in medical toxicology where you have written foreign issue regarding cadmium and no where is chronic poisoning party stated Where as environmental heavy metal is routinely found in soil, air vegetables milk, water and even (basen?) Can the high readings of cadmium in the hair be due to environmental exposure?
7:40 Very likely Not just environmental. There are so many confounding issues here. The fact that the hair samples have been handed down, person to person, we don’t know how flawless it was when finally, it was analyzed. I have my own grave doubts
8:00 that it was as flawless as we are expected to believe. I am sure that inevitably some contamination must have occurred. And leave aside that, as you have raised, it could be due to other factors like as environmental issues.. almost everyone offers hair when we look at it hair is something that is constantly exposed to the environment whether it is air or even water, or even other substances that we use such as chemicals or oil that we use in our hair, how you wash it there is always an issue that maybe can influence it’s results. So that is why hair has lost it’s appeal as a biological sample for toxicologist analysist. If at all you want to use it, it is not scalp hair it is pubic hair, because pubic hair is not exposed to the environment, like head hair is. So if at all you want to do hair analysis try to get hair from a part of the body that is not normally exposed to the environment. People go about exposing hair on their head. People don’t go about exposing hair elsewhere. You understand what I am saying so chances of contamination… if at you want to select a sample like that you should be very careful where you take it from Head hair to me not at all ideal because chances of contamination (is) very very high and the sources of contamination….
