All air-borne particles on which electrical forces exercise an essentially greater effect than the forces of weight and inertia are called air ions. Negative air ions exert a beneficial effect on animals and man. The most dangerous levels of harmful positive ions occur in the polluted, large industrial and heavily populated cities. Exhaust fumes from cars, trucks and buses, factory smoke, cigarette smoke, dust and soot, electromagnetic pollution and overall atmospheric pollution caused by air and sea crafts; all combine to create a mixture of harmful positive ions and reduces the production of beneficial negative ions in our surroundings. This gradually affects our lungs, can ruin our health and cause general lethargy and depression. All these modify the physics and chemistry of the human body. These environmental aspects will be adequately illuminated in this study.
