LUCKNOW: The latest urban air quality database released by the World Health Organization (WHO) says that India ranks among the world’s worst for its polluted air . Out of the 20 most polluted cities in the world, 13 are in India. The report reconfirms that most Indian cities are soon becoming death traps because of very high air pollution levels.India appears among the group of countries with highest particulate matter (PM) levels. Also, its cities have the highest levels of PM10 and PM2.5 (particles with diameter of 10 microns and 2.5 microns) when compared to other cities. Delhi is among the most polluted cities in the world today.Director general, Centre for Science and Environment (CSE), Sunita Narain says: “This database confirms our worst fears about how hazardous air pollution is in our region. Last year, the Global Burden of Disease study pinned outdoor air pollution as the fifth largest killer in India after high blood pressure, indoor air pollution, tobacco smoking, and poor nutrition. About 620,000 early deaths occurred in India due to air pollution-related diseases in 2010.”Narain added that 18 million years of healthy lives are lost due to illness burden that enhances the economic cost of pollution. Half of these deaths have been caused by heart disease triggered by exposure to air pollution and the rest due to stroke, chronic obstructive pulmonary disease, lower respiratory track infection and lung cancer.Experts claim that Indian cities are witnessing a rapid increase in air pollution and untamed motorization. Cities need to curb pollution from all sources, but vehicles need special attention as they emit toxic fumes within our breathing zone. India needs urgent action to leapfrog vehicle technology and fuel quality, scale up public transport, reduce dependence on cars, and promote walking and cycling.India is waiting for a decision on the emissions standards roadmap for vehicles and fuel quality from the Auto Fuel Policy Committee under the chairmanship of Saumitra Chaudhury, member, Planning Commission. This is expected to be announced soon, before the UPA II government is dissolved. The committee must respond effectively to the mounting evidences on worsening air quality and health damages associated with vehicular fumes.CSE suggests that the entire country should leapfrog to Euro VI standards by 2020-21. All cities need to implement clean air action plan to curb pollution from all sources to meet clean air standards in a time bound manner. Also, government must inform people about the air quality on a daily basis and issue health alerts for especially children, elderly, and those suffering from respiratory and cardiac problems.
