isoprene can also get to be a somewhat significant atmospheric component in some regions, especially during the summer, isoprene is pretty reactive, but i don't think the MSDS lists it as a carcinogen. of course the MSDS on pure oxygen wouldn't list that as a carcinogen either, which is kind of weird in the context of knowing that anti-oxidants prevent cancer.
reducing oxygen intake is healthy and good for you, people who live at high elevation locations with substantially less dense atmosphere get a tremendous health benefit out of it
