A thick layer of toxic smog covers most of northern India today, with air pollution in New Delhi exceeding levels 60 times higher than the World Health Organisation (WHO) limit, according to IQAir measurements.
The concentration of PM2.5 particles—the most dangerous as they enter the bloodstream directly—was recorded at 907 micrograms per cubic metre in some areas of the city, which houses 30 million residents.
PM2.5 particles are carcinogenic and enter the bloodstream via the lungs.
Every winter, the city faces record-breaking air pollution levels caused by toxic emissions from factories and vehicles, combined with seasonal agricultural stubble burning.
Lower temperatures and weak winds during the winter months, from mid-October to at least January, exacerbate the phenomenon.
Local authorities activated the highest level of their alert plan on Sunday afternoon to prevent further air quality deterioration.
Most schools in the area remained closed today, traffic restrictions were tightened, and employees were urged to work remotely until further notice. Schools are conducting remote learning, except for two secondary classes allowed in-person due to worsening air quality.
Additional measures include limitations on construction sites and diesel truck movement. The government also advised children, the elderly, and those with heart or lung conditions to “stay indoors as much as possible.”
According to the WHO, air pollution can cause cardiovascular and respiratory diseases and lung cancer.
A study published last June showed that air pollution accounts for 11.5% of deaths in Delhi, equivalent to 12,000 fatalities annually.
In October, India’s Supreme Court declared access to clean air a fundamental right, ordering national and state governments to take action.
