Big Trouble in the Air in India

NEW DELHI - Like many others of her age, 15-year-old Aastha Sharma, a Class 10 student at a private school in India’s capital, New Delhi, loves being outdoors, going for walks with her friends and enjoying an occasional ice-cream. But the young girl can’t indulge in any of these activities.

Chronic obstructive pulmonary disease (COPD), a lung disorder likely caused by Delhi’s heavily polluted air, has severely cramped the girl’s lifestyle, confining her mostly to her home.

For the past three years, Sharma’s life has been a whirligig of doctors’ prescriptions, missed social outings and a restricted diet that does not include most of her favourite foods.

NEW DELHI – Like many others of her age, 15-year-old Aastha Sharma, a Class 10 student at a private school in India’s capital, New Delhi, loves being outdoors, going for walks with her friends and enjoying an occasional ice-cream. But the young girl can’t indulge in any of these activities.

Chronic obstructive pulmonary disease (COPD), a lung disorder likely caused by Delhi’s heavily polluted air, has severely cramped the girl’s lifestyle, confining her mostly to her home.

For the past three years, Sharma’s life has been a whirligig of doctors’ prescriptions, missed social outings and a restricted diet that does not include most of her favourite foods. Along with books and a lunchbox, she also packs a nebulizer in her satchel daily to ward off the wheezing attacks that she has now come to dread.

“I’m sick of the endless do’s and don’ts I have to follow. When will I be able to lead a free life?” the teen wonders.

Many other youngsters in Delhi are asking the very same question as they grapple with the effects of rampant air pollution in this city of 18 million, believed to be world’s most polluted.

Particulate matter: a deadly matter

Greenpeace India, an environmental NGO, recently released findings of its air quality monitoring survey highlighting how poor the air was inside five prominent schools in the capital.

“Air pollution levels inside Delhi’s schools are alarmingly high and children are consistently breathing bad air. The new government needs to acknowledge the severity of air pollution in the city,” said Aishwarya Madineni, a campaigner with Greenpeace.

Another study conducted in 2014, which monitored 11,628 school-going children from 36 schools in Delhi in different seasons, found that every third child in the city had reduced lung function because of particulate pollution.

In a report submitted last year to the Supreme Court, the country’s Environment Pollution (Prevention and Control) Authority urged the apex court to order all schools in Delhi to shut down on days when air pollution levels posed a threat to public health.

Studies by the United States’ Environmental Protection Agency (EPA) point out that when children are exposed to particulate matter – a complex mixture of acids (nitrates and sulfates), organic chemicals, metals, and soil or dust particles – of 2.5 micrometers, it can trigger a raft of deadly respiratory illnesses.

The International Agency for Research on Cancer (IARC) classified particulate matter pollution as carcinogenic to humans in 2013 and designated it as a “leading environmental cause of cancer deaths.”

“Apart from mucous membranes and nasal cavities, air pollution also severely irritates eyes and skin. Exposure to high levels of pollution can lead to serious health [issues] in the long run,” warns Dr. Abha Sood, a senior consultant oncologist at the New Delhi-based Max Hospital.

Mothers’ exposure to pollution for prolonged periods, adds the specialist, can lead to malformation of organs in newborns.

“[Particulate Matter] of less than 10 micrometers in diameter (PM 10) is particularly insidious as it gets lodged deep inside the lungs and penetrates the bloodstream, heightening a person’s vulnerability to cancer and heart disease,” she explains.
