Indian Cities In Top 20 World’s Most Polluted Cities, Gurugram Tops List

While Delhi was again named the capital with the dirtiest air, in tenth place, neighboring business city Gurugram, which in 2016 changed its name from Gurgaon, took the not-so-coveted top spot.

Countrywise, India ranks third on the world ranking for highest PM 2.5 concentration, which are tiny particles believed to the most harmful for human health.

Air pollution, both outside and inside homes, is a silent and prolific killer responsible behind the premature death of seven million people each year, including 6,00,000 children, says David Boyd, a United Nations expert on environment and human rights.

PM 2.5 is the calculation of the fine particulate matter.

The report, Global Air Pollution 2018, was officially released on 5 March.

Gurugam topped the list as the world's most polluted city with PM2.5 soaring as high as 135.8 units in 2018. The topper of the list and the victor of the "most polluted city" tag was Gurugram (or Gurgaon), which lies in the NCR region of the country.

Three other Indian cities, and Faisalabad, in Pakistan, made up the top five.

But 64 percent of the cities surveyed exceeded this guideline.

The world's most polluted capital cities have been revealed - and Delhi has been exposed as the worst.

"This has enormous impacts, on our health and on our wallets". The World Health Organization (WHO) Air Quality Guideline recommends an annual mean exposure threshold of 10 μg/m3 to minimize health risks.

"A lot of households in South Asia rely on solid fuels, sometimes biomass, often coal, for their cooking and heating ... and there are often cities with large scale industries with poor emissions controls", he added.

Frank Hammes, the head of IQAir, said: "The 2018 World Air Quality Report is based on. data from tens of thousands of air quality monitoring stations around the world.

We still don't know the magnitude of air pollution problem in terms of PM2.5 monitoring", he said.

But critics have accused his administration of failing to adequately address environmental issues, including air pollution, and criticised New Delhi's recently-minted National Clean Air Programme (NCAP) as insufficient.
