The index categorizes conditions dictated by 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).

Moderate air pollution status dominated the month, keeping the index between 51 and 100 in 28 days. TAQCC data show that during the period, sensitive groups in the capital were warned to limit their outdoor activities in the remaining two days, as the index entered the threshold of 101-150 that categorizes the condition as “unhealthy for sensitive groups”.

Children, the elderly, pregnant women and those with respiratory and cardiovascular conditions fall in the above group.
