AirCare air quality analysis reports

Aug-12-2018: Air quality analysis for RxDx sensor for the period Jul-20-2018 to July-30-2018

Air quality data was collected from AirCare sensor during the period July-20-2018 to July-30-2018.

Location near RxDx has 3.5x times the pollution of other locations in Whitefield. The average PM2.5 value for the measurement period was 42μg/m3.

During the data collection period, the 24 hours PM2.5 average for the worst day at RxDx was 68μg/m3. At the same time it was 9μg/m3 from another AirCare sensor (benchmark sensor) at Ramagondanahalli. The WHO recommended annual average value for PM2.5 is 25μg/m3. There is no safe level for PM2.5. A long term exposure of PM2.5 at 40μg/m3 is associated with an increase in the long-term risk of cardiopulmonary mortality by 24-52% and lung cancer mortality by 32%.

The PM2.5 values at RxDx shows a huge variation of 19μg/m3 when compared to 4μg/m3 at the benchmark location.

Based on the pattern of pollution readings and visual observations, the pollution is caused by one or more nearby industries.
