New study sheds light on prevalence of pollutants in Indian cities According to the British study published in the journal “Atmospheric Chemistry and Physics”, hidden air pollutants are increasing in Indian cities

These pollutants include fine particles called PM25 along with nitrogen dioxide which are both hazardous to health Scientists used data from satellites to scan city skies every day They found that air pollutants were spread rapidly in Indian cities like Kanpur and Delhi

Pollution trends between 2005 and 2018 were taken into account by researchers, from the University of Birmingham and UCL, including a team of contributors from Belgium, India, UK Uni and Jamaica

Delhi already grapples with pollution every year as winter sets in the city, with a thick layer of smog covering the city’s skies year after year In 2018, the World Health Organization had ranked Kanpur as the most polluted city in the world According to the researchers, the increase in PM25 and nitrogen dioxide levels in the country can be attributed to increased vehicle ownership, industrialization and limited number of air pollution policies

In addition, scientists also found that formaldehyde, an air pollutant, had been spotted in Delhi and Kanpur, as well as in London The researchers juxtaposed data from Indian cities with data from cities in the UK

“We wanted to demonstrate the usefulness of satellite observations for monitoring city-wide air pollution in the UK where ground measurements are plentiful and in India where they are not. Our approach will be able to provide useful information on air quality trends in cities with limited surface monitoring capabilities. This is essential because the WHO estimates that outdoor air pollution causes 42 million deaths per year, ”said Karan Vohra, lead author of the study and doctoral student at the University of Birmingham, quoted by ANI
