Makes complete sense. We are what we eat and the same goes for any other creature or plant. If toxins can contaminate plants, animals, and humans then it is only reasonable that any element the organism comes in contact with can be revealed with the right technology. The paragraph "Humic acid in gold dissolution" also makes sense. Just as "For dust you are, and to dust you shall return". Everything is a cycle, whatever is alive breaks down and returns certain nutrients and elements to the soil. Whatver trace element is in that organism returns to the earth, there may be some elements that act as a catalyst and cause change to certain other elements but it all basically goes back to feed the cycle and balance of life. Very interesting, to me anyway.
