Geneva: India has four of the 10 cities in the world with the worst air pollution, the World Health Organization said on Thursday.But while WHO experts acknowledge India faces a “huge challenge“, many countries are so bad that they have no monitoring system and cannot be included in its ranking.The dirtiest air was recorded at Zabol in Iran, which suffers from months of dust storms in the summer, and which clocked a so-called PM2.5 measure of 217. The next pair were Indian -Gwalior and Allahabad -followed by Riyadh and Al Jubail in Saudi Arabia, then Patna and Raipur.
India's capital New Delhi was the survey's 11th worst city, measured by the amount of particu-late matter under 2.5 micrograms found in every cubic metre of air. Delhi had an annual average PM2.5 measurement of 122.
Tiny particulate matter can cause lung cancer, strokes and heart disease over the long term, as well as trigger symptoms such as heart attacks that kill more rapidly. The WHO says more than 7 million premature deaths occur every year due to air pollution, 3 million of them due to outdoor air quality.
New Delhi was ranked worst in 2014 with a PM2.5 reading of 153. It has since tried to tackle its toxic air by limiting the use of private cars on the road for short periods. Maria Neira, head of public health, environmental and social determinants of health at the WHO, praised India's government for developing a national plan to deal with the problem when others have been unable to.
“Probably some of the worst cities that are the most polluted ones in the world are not included in our list, just because they are so bad that they do not even have a good system of monitoring of air quality, so it's unfair to compare or give a rank,“ she said.
