Margin of Exposure

In Western Australia, the margin of exposure for various heavy metals and other pollutants that have been banned for over 40 years has been found to be lower in mothers-to-be.  Many pregnant mothers have been found with elevated levels of cadmium, mercury, and uranium in their blood.  This is especially disturbing as the direct effects on the unborn fetuses are reportedly unknown at this time.  High concentrations of these toxins can affect child mental development, as well as potentially increase the cancer risk in these newborns.  This article describes these recent findings in Western Australia.
