The lecture highlighted mechanism of the effect of the heavy elements and their toxic action against human body which is through generating free radicals which known in their damage to the structure of healthy cells and DNA, interfere with the work of some important enzymes and how these elements reach the human body through cigarette smoke, paints, polluted water and underground water.
