Why test for heavy metals?
The earth’s crust contains several naturally-occurring heavy metals. Some (like copper, zinc, manganese, selenium etc.) are essential nutrients - they need to be consumed for their effects on our functioning.
However, their multiple applications today (industrial, domestic, agricultural, medical and technological) have made them more prevalent in our surroundings and, therefore, food supply. This makes it important to ensure we don't consume higher quantities of them, for adverse effects on our health.
