- The PM2.5 particles weaken the inner lining of lungs: Experts
- The tiny PM2.5 particles can cause cardiovascular diseases: Doctors
- Pollution in Delhi had almost disappeared earlier during lockdown
New Delhi: Residents of the Indian capital are enduring one of the worst spells of air pollution in years, data released on Monday showed, raising the risks to city residents posed by the novel coronavirus, doctors said. Pollution in New Delhi had almost disappeared earlier this year, when the government imposed a nationwide lockdown to stop the coronavirus. But the curbs have been lifted and the pollution, and the virus, are back with a vengeance. Delhi‘s overall air quality index (AQI), which includes the concentration of PM2.5 particles as well as bigger pollutants, has stayed above 400, on a scale of 500, for five consecutive days, government data showed.
The tiny PM2.5 particles can cause cardiovascular and respiratory diseases including lung cancer, and pose a particular risk for people with COVID 19.
R.V. Asokan, the honorary secretary-general of the Indian Medical Association that represents 350,000 doctors, told Reuters the air pollution made people more susceptible to coronavirus infection.
The PM2.5 particles break the nasal passage barrier, weaken the inner lining of lungs, facilitating the spread of the coronavirus infection, Mr. Asokan said.
Doctors and researchers around the world have also reported a link between pollution and deaths in patients whose lungs are weakened by the novel coronavirus.
PM2.5 levels were 20 times the World Health Organization’s safe limit on Monday, official data showed.
The five days with an AQI above the 400 level is the longest spell of such heavy pollution in November since 2016. November is usually the worst month for pollution across north India as farmers burn off stubble in their fields and the cooler weather can trap the pollution.
Doctors in Delhi, which has reported a sharp increase in respiratory infections due to the pollution, are fearing a another jump after the Diwali festival on Sunday, which is celebrated with blizzards of smoky firecrackers, even though fireworks have been banned this year.
India’s main environment court, the National Green Tribunal, forbid the sale and use of firecrackers in the city of 20 million people, and neighbouring cities, from Monday to Dec. 1, but some people will inevitably ignore the order.
The court also told authorities to contain air pollution from all sources “in view of potential of aggravation of COVID-19”.
As well as the stubble burning, Delhi’s pollution issues are compounded by factories, vehicles and rubbish burning.
The neighbouring state of Punjab has recorded at least 50,000 crop waste fires this year, unchanged from a year ago, despite a campaign to encourage farmers to use other methods to clear stubble.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene.
