The 2019 World Air Quality Report published on Tuesday by IQAir AirVisual showed that Ghaziabad topped the charts of most polluted cities in 2019. It had an annual average PM 2.5 concentration of 110.2.

Delhi, the capital city of India, is the most polluted capital city in the world, with PM 2.5 concentration of 98.6.

The World Health Organisation's PM 2.5 standards say annual mean of 10 micrograms/cubic metre should be maintained.

The report noted a 20 percent decrease in national air pollution in India between 2018 and 2019 across 98 percent of the cities. However, it attributed the decrease to the economic slowdown in the country.

"Whilst cities in India, on average, exceed the WHO target for annual PM2.5 exposure by 500 percent, national air pollution decreased by 20 percent from 2018 to 2019, with 98 percent of cities experiencing improvements. These improvements are believed to be largely a result of economic slow-down," a statement issued by IQAir AirVisual said.

Industrial activities and vehicular traffic are significant contributors to air pollution in the Indian cities, along with rampant construction.

"While the new coronavirus is dominating international headlines, a silent killer is contributing to nearly 7 million more deaths a year: air pollution. Through compiling and visualising data from thousands of air quality monitoring stations, the 2019 World Air Quality Report gives new context to the world's leading environmental health threat," Frank Hammes, CEO of IQAir, said.
