A recent report published by Greenpeace India contains a list of 280 Indian cities ranked according to their particulate matter (PM10) levels. The data collated up to year 2016 in the ‘Airpocalypse II’ report reveals that over 80 per cent of the cities in the country do not even comply with the annual permissible concentration of 60 microgram per cubic metre (µg/m3) under the National Ambient Air Quality Standards (NAAQS), leave alone the World Health Organization (WHO) limit of 20 µg/m3. The Central Pollution Control Board (CPCB) has set the parameters under the provisions of the Air (Prevention & Control of Pollution) Act, 1981.

While the north Indian cities, with the national capital taking the top spot, are battling pollution problems, few cities down south along with those in Odisha, West Bengal, Meghalaya and Chhattisgarh managed to scrape through with their lower PM10 levels.

MakaaniQ shows the data below for the least polluted cities in India:

Karnataka

Cities namely Tumkur (144 µg/m3), Bidar (113 µg/m3), Bangalore (106 µg/m3), Davangere (84µg/m3), Raichur (88µg/m3) and Hubli (87µg/m3) fared poorly on the PM10 ranking. At the same time, the below-mentioned cities (with PM10 levels in µg/m3) displayed stark difference with their particulate matter levels well below the NAAQS limits. A special mention for Hassan, which has consistently appeared among the least polluted cities in India.

  • Hassan: 26 µg/m3
  • Bhadravati: 38 µg/m3
  • Karwar: 42 µg/m3
  • Mandya: 45 µg/m3
  • Chitradurg: 46 µg/m3
  • Mangalore: 47 µg/m3
  • Mysore: 48 µg/m3
  • Bellary: 54 µg/m3

Kerala

The hilly town of Pathanamthitta is the Hassan of Kerala with PM10 levels at 26 µg/m3, slightly above the WHO-recommended benchmark. Strangely, rivers in the state are getting choked with industrial effluents, but the air is clean with low amounts of particulate matter. Other cities (with PM10 levels in µg/m3) with lower PM10 levels are:

  • Pathanamthitta: 26 µg/m3
  • Alappuzha: 35 µg/m3
  • Idukki: 35 µg/m3
  • Malappuram: 37 µg/m3
  • Palakkad: 41µg/m3
  • Kasargod: 42 µg/m3
  • Kollam: 46 µg/m3
  • Kannur: 48 µg/m3
  • Wayanad: 50 µg/m3
  • Kozhikode: 51µg/m3
  • Kochi: 51µg/m3
  • Thiruvananthapuram: 53 µg/m3
  • Kottayam: 54 µg/m3
  • Thrissur: 55 µg/m3

The Central Pollution Control Board (CPCB) monitors air quality in cities at 87 real-time automated monitoring stations and other stations run by district pollution control committees. Sadly, a population of 550 million Indians reside in areas where the PM10 levels have crossed the safe NAAQS-levels, while 180 million live in areas with twice the stipulated standards. Moreover, there are still many districts in India, with a population of 580 million, for which air quality data is not available. Meanwhile, given below are the few lucky cities (with PM10 levels in µg/m3), including the picturesque town of Darjeeling, which have good air quality.

 Telangana

  • Khammam: 48 µg/m3
  • Karimnagar: 52 µg/m3
  • Kothagudem: 58 µg/m3
  • Nalgonda: 60 µg/m3

Tamil Nadu 

  • Cuddalore: 49 µg/m3
  • Salem: 51µg/m3
  • Mettur: 56 µg/m3
  • Coimbatore: 58 µg/m3

Others:

  • West Bengal, Darjeeling: 29 µg/m3
  • Puducherry, Karaikal: 35 µg/m3
  • Andhra Pradesh, Tirupati: 60 µg/m3
  • Meghalaya, Shillong: 59 µg/m3
  • Odisha, Rayagada: 59 µg/m3
  • Chhattisgarh, Korba: 58 µg/m3
  • Odisha, Berhampur: 58 µg/m3
