New Delhi: The Swiss firm IQAir in its ‘World Air Quality Report’ released on Tuesday ranked India the world’s eighth most polluted country in 2022, dropping from fifth place the previous year. In the list of most polluted cities in the world, out of the 50 cities, 39 are in India.

Chad, Iraq, Pakistan, Bahrain, Bangladesh, Burkina Faso, Kuwait, India, Egypt and Tajikistan were the top 10 most polluted countries while Australia, Estonia, Finland, Grenada, Iceland, and New Zealand met the World Health Organization (WHO) PM2.5 guideline (annual average of 5 Aug/m3 or less).

The data from 131 countries was taken from over 30,000 ground-based monitors, either government or non-government operated. As per the report, In India, the transportation sector causes 20-35 per cent of the PM2.5 pollution while other sources of pollution are industrial units, coal-fired power plants and biomass burning.

After the two top most-polluted cities, Lahore in Pakistan and Hotan in China, Rajasthan’s Bhiwadi is in third place and Delhi ranked fourth.

Delhi’s PM2.5 level is almost 20 times the safe limit, the report stated.

Delhi has so far been the most polluted capital in the world and the report made a distinction between ‘greater’ Delhi and New Delhi the capital. Both are in the top 10 and the infamous distinction of being the world’s most polluted capital goes to Chad’s N’Djamena.
