Heavy Smog Engulfs Tehran

Tehran has been suffocating under a blanket of smog over the past several days, as urban managers faced the public ire over their inaction.
In a meeting held on Friday, Abdolreza Cheraghali a deputy governor general, said the Air Pollution Emergency Committee convened on Saturday to find solutions for curbing air pollution, Mehr News Agency reported.
“The Health Ministry, the University of Medical Sciences and the Department of Environment presented the committee with reports on the situation and pitched solutions. More stringent traffic rules or partial lockdown were among the options,” he said. 
Cheraghali noted that December 2020 was one of the most polluted months in Tehran over the past several years and the high level of air pollution is expected to persist until Tuesday.
Charts regularly published by Tehran Air Quality Control Company’s website, Airnow.tehran.ir, illustrate that the capital’s residents inhaled more polluted air in December 2020 compared with the same month of last year.
During the month, Air Quality Index did not enter the range of good air quality even for a single day.
AQI categorizes conditions dictated by a measure of polluting matters into good (0-50), moderate (51-100), unhealthy for vulnerable groups (101-150), unhealthy (151-200), very unhealthy (201-300) and hazardous (301-500).
