The air we breathe is essential to our body as it needs enough supply of oxygen in order to maintain the healthiness of the organs and the systems of the body.
Some countries already developed several policies to reduce air pollution. But there are still numerous industries and other factors that contribute to the severity of the case mostly in the developing countries. The most harmful pollutant called the PM 2.5 is a tiny particle commonly found in soot, smoke and dust. This tiny pollutant causes chronic lung illnesses when it has penetrated the lungs.
The Particulate Matter (PM) is composed of sulfate, nitrates, ammonia, sodium chloride, black carbon, mineral dust and water. Usually, those with diameters less than 10 microns are already considered the most-harmful health damaging particles that can severely affect the lungs, according to the World Health Organization.
