Well if someone teases you now of staying in the most polluted city(Delhi), do show them this. If news reports over the past few years are to be taken into account, it has been Delhi. But according to a new report published by IQAir AirVisual and Greenspace, two non-profit organisations based in the country, the capital city is not in fact the most polluted city in the world, it is Gurgaon.
As the report says, India is abode to seven out of the 10 most polluted cities in the world. Delhi ranks 11 on the chart, preceded by Ghaziabad, Faridabad, Bhiwadi, Noida, Patna and Lucknow. The study lists cities on the pollution chart based on the aggregate levels of Particulate Matter (PM) 2.5, exposure to which increases the risk of lung cancer, strokes, heart attack, and respiratory diseases. The data published in the report has been collected from public and government websites in real time. In such instances where real time data was not available, "queries were performed to collect historical data when it becomes available."
Even in the last year, environmental reports indicated Delhi to be the world’s most polluted city. The fall in its rank on the pollution chart suggest the fact that the city’s air quality is gradually but of course improving. Even Beijing, whose quality of air was considered as fatal until a few years back, has made huge efforts for sure to improve it since 2013. The government and citizens of the capital city need to join hands to further heal the city’s disastrous environmental problem. Only spreading awareness and taking even baby steps towards protecting the environment amounts to a huge contribution in the present state.
