Air quality monitoring stations around the capital city show residents took an easier breath in November compared with the corresponding month of 2019.
Based on data published by Tehran Air Quality Control Company on its website, Airnow.tehran.ir, the capital experienced fewer polluted days in November compared to a year earlier.
During the month, the air quality chart was dominated by ‘moderate’ status, with Air Quality Index hovering between 51 and 100 on 22 days.
The index categorizes air conditions according to a measure of polluting matters into good (0-50), moderate (51-100), unhealthy for sensitive groups (101-150), unhealthy (151-200), very unhealthy (201-300) and hazardous (301-500).
Charts published by TAQCC show that sensitive groups in Tehran were advised to limit their outdoor activities on eight days, since AQI hovered between 101 and 150, marking an unhealthy status for the group.
Children, the elderly, pregnant women and those with respiratory and cardiovascular problems, all of whom fall in the sensitive group, are classed as sensitive.
