Don't mean to be a wet blanket, but it seems to be a typical media alarmist article. Nowhere is there any mention of the levels of these substances and whether or not they are at dangerous levels. What about whether this is an increase or decrease from prior tests? What about the toxic chemicals some of you willingly put (or used to put) in your body for a high? Are you worried about the negative effects of that, too?
Remember, people are living on average longer than they were 50 years ago.
I'll take the info in this article with a grain of salt (but not too much salt, since I don't want to risk increasing my blood pressure )
