In the Greenpeace report, the city-based rankings differ, with Delhi taking the 11th spot as the most polluted city and Gurugram at the top, with an annual average PM2.5 reading of 135.8 micrograms per cubic meter.
Gurugram World’s Most Polluted City
Gurugram led all cities in pollution levels in 2018, even as its score improved from the previous year, according to data released by IQAir AirVisual and Greenpeace. Three other Indian cities joined Faisalabad, Pakistan, in the top five.
Seven of the top 10 most polluted cities in the world are in India, according to a new study showing South Asia’s battle with deteriorating air quality and the economic toll it’s expected to take worldwide.
Gurugram, located southwest of India’s capital New Delhi, led all cities in pollution levels in 2018, even as its score improved from the previous year.
According to the latest data compiled in the IQ Air Visual 2018 World Air Quality Report and interactive world’s most polluted cities ranking, which is prepared in collaboration with Greenpeace Southeast Asia in order to reveal the state of particulate matter (PM2.5) pollution in 2018, Delhi had an average yearly PM2.5 concentration at 113.5 micrograms per cubic metre.
The report is based on air quality data collected in 2018 from public monitoring sources, with a special focus on data which has been published in real-time or near real-time.
“These sources include government monitoring networks as well as validated data from air quality monitors operated by private individuals and organizations”, the reported stated.
However, the city-based rankings differ, with Delhi taking the 11th spot as the most polluted city and Gurugram at the top.
Ghaziabad is number 2 with 135.2 micrograms per cubic meter and Faisalabad in Pakistan is third with 130.4 micrograms per cubic meter.
According to the National Ambient Air Quality Standards, the annual permissible limit for PM2.5 is 40ug/m3. The annual permissible limits prescribed by the World Health Organization are even lower at 10ug/m3.
The index measures the presence of fine particulate matter known as PM2.5, a pollutant that can fester deep in the lungs and bloodstream of human beings.
“This has enormous impacts, on our health and on our wallets,” Yeb Sano, executive director of Greenpeace Southeast Asia, said in a statement released with the figures. “In addition to human lives lost, there’s an estimated cost of $225 billion in lost labor and trillions in medical costs.”
India, the world’s fastest-growing major economy, makes up 22 of the top 30 most polluted cities, with five in China, two in Pakistan and one in Bangladesh. India racks up health-care costs and productivity losses from the pollution of as much as 8.5 percent of the gross domestic product, according to the World Bank.
China made marked progress in its usually dismal pollution levels, with average concentrations falling by 12 percent in 2018 from the previous year, according to the data. That should help the message President Xi Jinping will share with political party leaders on progress across three so-called “critical battles” during the National People’s Congress meetings that start this week.
