Delhi and Varanasi are among the 14 Indian cities that figured in a list of 20 most polluted cities in the world in terms of PM2.5 levels in 2016, the latest data released by the World Health Organization. The WHO data also said that nine out of 10 people in the world breathe air containing high levels of pollutants. Other Indian cities that registered very high levels of PM2.5 pollutants were Kanpur, Faridabad, Gaya, Patna, Agra, Muzaffarpur, Srinagar, Gurgaon, Jaipur, Patiala and Jodhpur followed by Ali Subah Al-Salem in Kuwait and a few cities in China and Mongolia.
In terms of PM10 levels, 13 cities in India figured among the 20 most-polluted cities of the world in 2016. This is what is causing huge worry. The World Health Organisation has called upon member-countries in its Southeast Asia Region to aggressively address the double burden of household and ambient (outdoor) air pollution, saying the region, which comprises India, accounts for 34 percent or 2.4 million of the seven million premature deaths caused by household and ambient air pollution together globally every year.
Of the 3.8 million deaths caused by household air pollution globally, the region accounts for 1.5 million or 40 per cent deaths, and of the 4.2 million global deaths due to ambient air pollution, 1.3 million or 30 per cent are reported from the region, it said. The PM2.5 includes pollutants like sulfate, nitrate and black carbon, which pose the greatest risk to human health.WHO’s global urban air pollution database measured the levels of fine particulate matter (PM10 and PM2.5) from more than 4,300 cities in 108 countries, according to which ambient air pollution alone caused some 4.2 million deaths in 2016, while household air pollution from cooking with polluting fuels and technologies caused an estimated 3.8 million deaths in the same period.
Since 2016, over 1,000 additional cities have been added to WHO’s database, which shows more countries are measuring and taking action to reduce air pollution than ever before. According to the report, more than 90 per cent of air pollution-related deaths occur in low- and middle-income countries (including India), mainly in Asia and Africa, followed by low- and middle-income countries of the Eastern Mediterranean region, Europe and the Americas.
