The data was recorded by cali-brated air quality monitors fixed at particular positions with proper readings. However, concentrations of PM2.5 during the day and evening times were recorded slightly high whereas the overall ambient air quality of the federal capital was not healthier today.

Any other data from any source presenting ambient air quality ofIslamabad was neither verified nor approved by the PAK-EPA, the re-port said.Earlier, an EPA official told APPthat dust count was higher due to construction at the Faisal Avenue which was monitored through its on-line air quality system.She went on to mention that theEPA team had also visited the sitewhere the contractor was found violating the pledges he made underthe EIA submitted to the Agency.
