In a recent air monitoring survey, Delhi/NCR has been found to have deadly PM2.5 levels that are 10 times higher than the safety limit prescribed by the World Health Organisation (WHO), and four times higher than even the Indian safety limit. According to the study, Delhi’s air has high concentrations of PM2.5 — particulate matter less than 2.5 micrometers in diameter. This is believed to pose the greatest health risk because it penetrates deeply into lungs. The PM2.5 limit prescribed by the World Health Organization is 10 micrograms per cubic meter, and the Indian limit is 40 micrograms per cubic meter. PM2.5 is a collection of miniscule particles in the air that reduce visibility, cause the air to appear hazy, and affect respiratory tracts. Delhi’s air has been therefore declared the most polluted in the world. With this alarming declaration there are major initiatives underway by both the central and state governments, as well as environmental agencies such as the National Green Tribunal to reduce the deadly pollution adversely affecting Delhi’s air. Companies, industries and individuals are being encouraged to do their bit to reduce the impact of the deadly air pollution that is slowly making Delhi a city difficult to live in.
