Air pollution reduces life span by 3.2 years in India

Air pollution is a serious problem in our society these days. We come across it indoors, when people have been smoking, and outdoors, where motor vehicle exhaust pollutes the air. For years scientists have been warning us that polluted air is a hazard to our health. It seems these warning are not being taken acutely enough. The truth is that air pollution is growing worse, especially in compactly populated societies

On this (WHO data) score, 13 of the world's 20 most-polluted cities are all in India. And India's cities have much higher PM2.5 levels than China's India and China, of course, didn't invent air pollution. Cities like London and Los Angeles also once had horrific smog and particulate problems. But as they got richer, they cleaned up — and there's every indication that developing countries will do the same. The question is when.

China, for its part, has already begun to crack down on its air pollution, through policies to limit coal burning in cities and curtail vehicle use. The study says it makes economic sense to combat air pollution as it “increases productivity due to reduced rate of sickness”. Another author Rohini Pande of Harvard Kennedy School says reforms of thae current form of regulation would allow for health improvements that lead to increased growth.

High exposure to particulate of 2.5 microns that penetrate deep inside the lungs can cause cardiovascular problems apart from enhancing breathing ailments. Extremely high exposure for a long time can also cause lung cancer.

The study also says that 54.5% of Indians are exposed to high levels of fine particulates (PM2.5) as air quality in these regions don’t meet the national air safety standard. The Indian standard of 40 unit grams in cubic meter of air (ug/m3) is four times of the one prescribed by the World Health Organisation (WHO).“Nearly every Indian lives in an area with PM 2.5 pollution above the WHO standard,” the study said. So far, India has taken fewer steps in that direction. One reason for that is that India is still much, much poorer than China. (Among other things, India has 400 million people without electricity; China has virtually none.) So the country is still focusing heavily on economic growth — which often means expanding the use of fossil fuels. That said the problem has gotten so bad of late that India's policymakers are beginning to take notice. In November 2014, Prime Minister Narendra Modi announced he would make air-quality data available to the public and pledged to set new emissions standards for power plants.

We can prevent air pollution effort of industries have been generally focused on the Air Quality by using Air pollution control equipment around the work place by using Dust Collector, Wet scrubber, and harmful fumes generating from welding, soldering are been removed by using Fume extractor, if we use these air pollution control Equipments we could have a better pollution free world.
