Drop In Mercury Turns Delhi Air 'Severe'

With toxic pollutants reaching 'severe' levels in Delhi, experts have advised to avoid all physical activity outdoors, including morning walks and not to rely on dust masks for protection against pollutants.

In Delhi-NCR, the sharp drop in the minimum temperature which caused the air quality to turn severe will remain so till today, hence physical outdoors should not be encouraged.

"Overall air quality in Delhi is in the severe plus zone and it is expected to remain in that range until tomorrow. Thereafter, it will start to improve slowly and may touch 'very poor' category," System of Air Quality and Weather Forecasting And Research (SAFAR) said in its forecast.

Air Pollution - Pollutants - Health Effect - Efforts to Reduce
Nearly 2.4 million deaths every year are attributable to air pollution. Air pollutants may be solid particles, liquid droplets or gases. Proper planning methods should be adopted to reduce air pollution.

‘In terms of pollution, the Air Quality Index (AQI) of Delhi was recorded at 471. The average concentration of particulate matter (PM2.5 and PM10) in Delhi was also in the 'severe' category at 408 and 588 microgrammes per cubic metre, respectively.’

Delhi recorded the coldest morning on Sunday in December with the minimum temperature dropping to 3.7 degrees Celsius but the Met predicted an increase in temperature over the next few days.

"Currently, cold wave conditions are prevailing over northwest India which is causing the temperature in Delhi and adjoining areas to drop significantly but over the next two-three days, southwesterly winds will come in and increase the temperature by one-two degrees," an India Meteorological Department (IMD) official said.

The fall in temperature has also led to moderate to dense fog during the morning with visibility in Safdarjung area observed around 300 metres at 8.30 a.m.
