Chemical #1 may cause blue, #2 red, #3 green, etc etc. But all of the chemicals may originate from many different sources. And the most common source is the very air you breathe. And of course the air always, stress always, contains a widely varied mixture of different chemicals.</p><p><br /></p><p>So the answer to your question is - exposure to chemicals. </p><p><br /></p><p>And it doesn&#039;t matter if that exposure happens over a long time or it happens in an hour, the time element is merely determined by the concentration of the chemicals.[/QUOTE]</p><p><br /></p>
