You have kidneys, a liver, and a lymphatic system that all work wonders against small invaders in small quantities, perfect for the situation described with the "PPM" metric. We all love buying into these "it's xyz killing me!" stories but whats most likely causing you to feel terrible or potentially killing you is your lack of (quality) sleep, excess of stress, poor diet or potentially a combination of all three. And if I may throw my two cents in, humans were "designed" to live right around somewhere in the 60-70 range. This has been true since we kept track of humans, at least.
