How are environmental toxins affecting us? What's the Dirty Dozen? Seven billion pounds of environmental toxins are being dumped into our air and water each year. These heavy metals, chemicals, herbicides, and pesticides then enter our bodies – stockpiling in our brain, heart, bones, liver, and other organs – literally stealing our health. These destructive agents load up in our body in the form of toxic metals and other harmful chemicals that simply cannot be shed by normal body processes.
