According to the Moj news agency, based on the forecasts made in the control company Air quality in Tehran This morning (December 22), due to the lack of effective wind during the past hours and the accumulation of pollutants along with the increase in morning traffic, the air quality in some high-traffic areas will be in the unhealthy and unhealthy range for sensitive groups. With the continuation of the stability of the atmosphere during the day, the concentration of pollutants will increase.
The continuation of these weather conditions and the lack of effective wind along with the increase in evening traffic until late Tuesday will result in an increase in the concentration of suspended particles and the establishment of an unhealthy and unhealthy situation for sensitive groups in most areas.
With the relative increase in wind speed, the concentration of suspended particles will be reduced to some extent by tomorrow morning (December 23), although the increase in the concentration of suspended particles and the decrease in air quality in high-traffic areas will not be far from expected at the same time as the traffic of cars begins. Reducing wind speed during the day will prevent the dispersion of pollutants.
With the formation of atmospheric instability and the growth of cloudiness and the possibility of scattered rain until late Wednesday, the conditions for the dispersion of pollutants will be provided, although the establishment of an unhealthy situation for sensitive groups is expected in most high-traffic areas due to the increase in evening traffic.
According to the air quality control company, the pollutant index of “suspended particles less than 2.5 microns” is now at 142, which means unhealthy conditions for sensitive groups. Also, the pollutant index of the capital’s air in the last 24 hours is “suspended particles less than 2.5 microns”. with an average of 139, and the air quality of the capital was in unhealthy conditions for sensitive groups.
Therefore, according to the precautionary instructions issued by the Tehran Air Quality Control Company, people suffering from heart or lung disease, the elderly and children are among the sensitive groups and should reduce long or heavy outdoor activities. Prolonged activity is any outdoor activity that people do intermittently for several hours and causes breathing to be somewhat harder than normal.
