I do not concern myself about "scary" chemicals. Of course massive amounts of anything (even water) can be harmful.
Nature has equipt the human body with a massive filter, called the liver, and several ways of excreting (such as sweat, urine, breath and so on) chemicals the body doesn't need, can't use or are harmful.
