While heavy metals can be naturally excreted by the body through sweat and urine, if they are consumed in high amounts they can accumulate in the body and damage major organs.
The contamination of soil within the agricultural industry by toxic heavy metals — such as mercury, lead, and cadmium — is currently a large issue. These heavy metals can then leach into the ...
