New Delhi: Outdoor activity, including streets, must be avoided until 10 am in the winter.
Reason: Analysis with air quality systems and weather forecasting and research, forecasting under the UNI Minister of Earth Sciences, found PM2.5 peaked between midnight and 10 in the morning.
Experts say calm winds, low night temperatures and high mixing layers low in this period cause accumulation of pollutants.
Safar analysis for hours between 2pm and 6pm, although also polluted, relatively better than in the morning.
According to Safar, the concentration of PM2.5 per hour on average at midnight in the days between 12 November and 17 was 246 micrograms per cubic meter.
It rose to 304 micrograms per cubic meter at 11 am, but was reduced to 158 micrograms per cubic meter to 2PM and further to 128 micrograms per hour 16:00.
Then it rises to 158 micrograms per cubic meter at 6pm and continues to rise further at night.
Safar analysis is based on the concentration of PM2.5 per ordinary hour.
It should not be confused by reading PM2.5 on average 24 hours.
Gufran Beig, Director of the Founding Project Safar, said, “People must limit their outdoor activities during the rush hour of PM2.5 concentration.
Period during the afternoon and evening polluted, but it is relatively better than rush hour.” Confirm this, Tanushree Ganguly, leading The program, the energy, environmental and water council, said that for the past few days, PM2.5 levels peaked at night and morning hours in Delhi because the wind was relatively quiet around the times.
“The surface that faster supports dispersion of pollution, but the wind is relatively more calm inhibiting their dispersal,” he said.
Anumita Roy Chowdhury, Executive Director, Research and Advocacy, Science and Environment Center, explained, “Inversion conditions are deeper at night that intensify pollutant traps.
Because of the cool, calm and stable atmospheric conditions, air cannot rise high enough for mixing and dispersion Effective.
“He added,” The relative increase in atmospheric conditions during the day allows a better dispersion of pollutants.
This is the reason why we see relatively lower pollution buildup in the afternoon in the winter.
“Experts say exposure to concentration PM2.5 High can be dangerous.
Arun Sharma, who was previously with the University of the College of Medical Sciences and currently Director of ICMR-NIIRNCD, Jodhpur, said, “If someone with healthy lungs breathes large amounts of PM2.5, small pollutant particles past the throat and get stored in the lungs .
These toxic elements can cause difficulty in breathing.
If the particles deposited in the eyes, it causes itchy and watery eyes.
“Sharma warned that exposure to PM2.5 for a longer duration of approximately eight hours each day will allow the particles to be stored in the lungs in a progressive way and damage the lungs.
“In addition, PM2.5 long exposure can worsen the health condition of people who suffer from asthma and other lung diseases,” he said.
That morning walking in Delhi can make you more dangerous than kindness
