A recent study has concluded that New Delhi is the world’s most polluted capital for the second straight year in 2019. This is bound to have an impact on the weather patterns of Sri Lanka since India is situated in close proximity.
According to the study, India was also home to 21 of the world’s 30 most polluted cities. The study measured the concentration of poisonous PM2.5, particles that are less than 2.5 microns in diameter and can be carried deep into the lungs, as higher PM2.5 levels could cause deadly diseases, including cancer and cardiac problems.
In 2019, New Delhi’s average annual concentration of PM2.5 in a cubic meter of air was 98.6, the study said, more than double the level of Beijing, which averaged 42.1 during the year, making it the ninth most polluted city in the world.
