Drinking water, grains, produce, and dairy products from animals raised on contaminated soil may contain elevated levels of perchlorate. The effect was similar to that seen in infants whose mothers smoked during their pregnancy. Therefore, it is important to clearly evaluate how the various elements as articulated by Hill fit the EDC debate Table 3. A shortage of fresh water is often why some urban households do not have a safe and adequate water supply.

Foods rich in glutathione are garlic, onions, cabbage, walnuts, and lamb. Moreover, chemical exposures do not occur in isolation and, even in newborns, there are literally dozens of chemicals found in the bloodstream [ 50 ]. The nature of causation is a core issue for science, and there is a great deal written on this subject [ 52 ]. Environmental health is the public health field that monitors and addresses those physical, chemical, and biological factors that we might not have direct control over, but can impact our health anyway.
