Once we absorb things like Lead, Mercury, Dioxins, Pesticides etc, they cannot be easily eliminated from the system, and can accumulate. Go and have a blood test looking for heavy metals, and toxic substances like dioxins, you may be shocked. Dioxins are in things like DDT (pesticide) Agent Orange (herbicide) Once they are in the environment they permeate the environment. They can be banned, but they will never go away - Some of them are refined Elements. That also includes depleted Uranium, and of course Chronic Lead poisoning (Gunshot Wounds)

gives a whole new meaning to the expression "get the lead out!"
huh?

Being a "boomer" and seeing lead paint banned, restrictions and banning on food coloring, and evidence of the harmfulness of inhaling specific fumes (to name a few of the health related revelations that have happened in my lifetime) I fear every day for my health.
