I'm sorry, I don't understand the question, anymore.
In Chemistry I, my teacher has asked me to determine and discuss the role of traces of gold in human hair.
And you found a reference, with something of a conclusion in its abstract. Then you ask:
Ok...looks like if I determine the significance of the other elements mentioned, I can determine the importance of gold, correct?
I have been looking all day for the significance of gold in human hair. I know it is present, and I know how much is present, but I want to know how and why gold is in hair.
What do you mean, significance. And why do you need this answer. Your link says there isn't one, its just a coincidence. So why do we have to find one for you?
