‘It’s like the killer Great Smog of London’

AIIMS Director Randeep Guleria has compared Delhi air pollution to the killer Great Smog of London of 1952. Dr. Guleria, a renowned pulmonologist, said that N95 masks and air purifiers, whose sale has increased in the last few days, may not provide full-time protection and stressed on implementation of long-term measures to tackle the crisis.

“Patients have started coming to the OPDs with complaints of breathlessness, coughing, sneezing, tightness in chest, allergy and asthma complications. There is about 20 per cent rise in patients seeking treatment due to respiratory and cardiac issues,” Dr. Guleria said adding that pollution is at such a severe level that patients with respiratory and cardiac problems may develop life-threatening conditions. “This is a silent killer,” he said.

On December 5, 1952, a thick yellow smog brought London to a standstill for four days and is estimated to have killed more than 4,000 people.Read more.

There was a spurt in fresh cases in Delhi hospitals and conditions of patients with history of asthma, Chronic Obstructive Pulmonary Disorder (COPD) and cardio-vascular diseases deteriorated.

The state-run Safdarjung hospital witnessed an increase in such patients in its OPDs and casualties over the past two days, professor and head of pulmonary medicine at the hospital J.C. Suri said. He said the immediate effects are cough, throat infections and pneumonia, but in the long term the results could be disastrous as one could also develop lung cancer.

“Elderly and children are more likely to develop infections and allergies due to smog and pollution. So they should avoid going out during the early morning and at dusk hours when the toxic level is at its peak,” Dr. Suri said. “Also, when pollution levels rise, the condition of those suffering from Chronic Obstructive Pulmonary Disease (COPD) or asthama or heart disease worsens,” he said.

Waltch: Delhi in the grip of smog

A combination of smoke from stubble burning in Punjab and Haryana and moisture turned Delhi into a “gas chamber”, prompting the authorities to announce a series of preventive measures, including a four-fold hike in parking fees and slashing of metro fares.

The AQI data collected from 15 monitoring stations showed that particulate matter — both the smaller PM2.5 and the coarse PM10 — were the prominent pollutants in the cityi. Across the National Capital Region, Faridabad, Ghaziabad and Noida also had severe pollution, while Gurugram fell in the “very poor” category.

The level of the harmful PM2.5, which is small enough to get embedded in the lungs causing serious respiratory illness, was several times over the standard of 60 micrograms per cubic metre.
