Air pollution is a significant health risk factor all over the world. A global study of diseases showed that air pollution is one of the top ten global health risk factors. Approximately 7 million people in the world and 40, 0000 people experience early death due to air pollution. The most common pollutants include particulate matter, carbon monoxide, ozone, nitrogen oxide, and sulfur dioxide. The two types of air pollution, indoor and ambient, both contribute to a host of cardiac and respiratory illnesses. General ambient air pollution, chiefly due to the incomplete combustion of fossil fuels, may be responsible for increased rates of lung cancer. Exposure to excess levels of air pollution is significantly associated with a variety of acute and chronic respiratory illnesses, such as chronic obstructive pulmonary disease, asthma, respiratory allergies, and lung cancer. The effects of air pollution disproportionately impact the extremes of the age distribution, perhaps due to altered immune responses. The presence of one or more contaminants in the atmosphere, such as dust, fumes, gases, gas, ‘fog’, odour or vapour in quantities or with characteristics, and of a duration that may be detrimental to human, animal or plant. Combustion-source air pollution contributes to the occurrence of lung cancer among the general population. By using modern techniques to control pollution Multi-vortex wet air scrubber’s technology, nano technology, recycle reuse techniques is very helpful to control pollution.
