Tehran Ozone Alarm Goes Off

With the onset of summer, air pollution control stations around the capital city of Tehran are recording more days with high-density ozone pollution, which have a harmful impact on citizens’ health and the environment.
According to the data published by Tehran Air Quality Control Company, in the past three weeks starting July 1, Tehran’s residents have been exposed to high levels of ground-level ozone, an uncommon air pollution that becomes a regular phenomenon as temperature rises. 
Based on TAQCC charts, during the period under review, high ozone level pushed Air Pollution Index into the “unhealthy” threshold for the sensitive group on 11 days. 
The group comprises people with cardiovascular and respiratory diseases, pregnant women, children and the elderly. In the remaining six days, the index hovered in the moderate range.
