I learned in my course that environmental pollutants such as lead, mercury and other heavy metals will bioaccumulate in the females body's and become part of the bone and calcium structures. These accumulated heavy metals will be passed on the the fetus through the fetal developmental stage and breast feeding period.
That leads to bio-magnification where even a newborn has trace amount of heavy metals that are detrimental to intelligence and devlopment and this amount gets bigger in quantity as the newborn becomes parents and repeats the cycle.
