Beyond Delhi: Cities with much worse air quality than the national capital get little attention

Though almost the entire debate on air pollution has been centered around Delhi, there are several cities and towns in India which have much worse air quality than the national capital. Just outside Delhi, Ghaziabad is one of the most polluted cities in the country.

The Central Pollution Control Board has been running a National Air Quality Monitoring Programme since 1984 under which three pollutants — sulphur dioxide (SO2), nitrogen dioxide (NO2) and particulate matter of less than 10 micron (one micron is a millionth of a metre) (PM10) — are monitored. This programme now covers 254 towns and cities in 29 states and five union territories. There are 612 operating monitoring stations in these places which continuously collect data on these three pollutants.

There are 46 cities in the country with a population of one million or more. These are also amongst the most polluted. We have featured four of these cities here. Based on the average concentration of PM10 in 2013, the last year for which full data is available, Raipur in Chhattisgarh was the worst polluted million-plus city in the country, followed by Ghaziabad, Allahabad and Delhi. The acceptable limit of average annual PM10 concentration is only 60 micrograms per cubic metre (mg/cu m) but Raipur had a concentration of 305 mg per cubic metre in 2013.

Here are four other cities that are battling pollution in its own way:-

                                        

     

    Raipur: New capital high on the ‘dirty list’

Raipur has been the state capital for merely a decade and a half, but over the past few years, the city has consistently figured among the most polluted urban centres in India.If you have driven in Raipur, you probably would never have been stopped and asked for a pollution certificate. For a city where the pollution graph is disturbing for its size, that is a big concern.

                                

                                           

                                    Kanpur: Dust, diesel fumes choke industrial hub

CPCB’s North Zone office in-charge in Lucknow, PK Mishra, attributes Kanpur’s polluted air to a combination of factors.

Kanpur Municipal Corporation’s safai karamcharis burn waste collected from residential areas and markets within the localities instead of transporting it to primary collection points. Residents, too, burn domestic waste on roadsides. In winter, slum inhabitants and vendors burn plastics and tyres as bonfire.

                             

                                            

                                            Ludhiana: More wheels on the road

                                                 

In 2011, a WHO report named Ludhiana as the country’s “most polluted city”, but that didn’t set alarm bells ringing. In 2015, the city added an average of 10,000 private vehicles every month. There are more than 17,000 illegal diesel autos on the roads, despite a 2009 ban by the Punjab and Haryana High Court on registration of new diesel autos. “The ban was on issuing permits for diesel autos within city limits. Autos that get permits for plying outside the city flout rules and run within the city,” said Richa Agniotri, ACP (Traffic). The city has just one LPG filling station, on the outskirts, and thus LPG autos too run illegally on subsidised kitchen LPG cylinders.

                             

                                            

                                                   Allahabad: Poor public transport

Five instruments set up by the CPCB in different parts of Allahabad have been sending out alarming statistics about the quality of air in the city. But the authorities don’t think there is a problem yet. “The air quality is not as bad as in other cities,” said Sanjiv Pradhan, Environment Engineer of Allahabad Municipal Corporation.
