Particulate matter is particularly troubling. And now we have this study as further evidence. There is no way to avoid the issue of detoxifcation in our current environment. These airborne toxins are breathed in with every breathe but they also enter the water and food supply. The human body often lacks any sort of metabolic pathway to package them and get them out. They interfere with normal metabolic detoxification and destroy enzyme systems and nutrient levels. Because they body can't get rid of them they circulate perpetually through the blood stream wreacking havoc along the way. This puts a special burden on the liver, kidney, lungs, heart, and brain leading to systemic inflammation and many diseases besides cancer.
