Heavy Metals

About Heavy Metals

The US Federal Drug Administration (FDA) identifies cadmium, arsenic, lead, and mercury as class 1 toxicants, meaning they have no reasonable use in the manufacture of pharmaceuticals. These four heavy metals are particularly dangerous, because the body cannot effectively remove them. Heavy metals bind to vital cell structures and interfere with processes like cell replication, protein assembly, and enzyme production. All the class 1 heavy metals are potentially carcinogenic. Long-term exposure could also lead to kidney damage, softening of the bones, tremors, palsy, encephalopathy, diabetes, anemia, and lung scarring.

Reporting

In compliance with MRA Rule 47(8), samples containing heavy metals with a higher value in parts per million (ppm) than the acceptable action limit are determined to have failed testing.
