GUWAHATI: In a day, the air quality level in Guwahati is at its worst between 6-8 pm as the pollutants in the air (PM 2.5) is recorded to be the highest on an average during 6-8 in the evening.

This was revealed by analysing two month’s data obtained by the continuous air quality monitoring station at Pollution Control Board of Assam (PCBA) and the results showed that Guwahatians are most prone to toxic air during the evening hours.

Further, according to the data, the city’s air pollution levels showed an increasing trend over the past two months. The average PM 2.5 level in the month of October in Guwahati was 53.36 while this increased sharply to 97.9 in November.

PM 2.5 are fine particulate matters suspended in the air measuring two and a half microns or less in width. There are around 25,000 microns in an inch. Presence of high levels of PM 2.5 in the air reduces visibility and causes the air to appear hazy and can pose serious health-related risks among people including respiratory issues.

The highest PM 2.5 level as recorded in an hour in October was 290, whereas the lowest was 1.

Further, as per the data the highest PM 10 level for October was 1000 while the lowest PM 10 level in October was 18. PM 10 is another air pollutant PM 10 which is particulate matter measuring 10 micrometers or less in diameter was 215.2.

Currently there are six air quality monitoring stations in Guwahati and 23 stations all over the state which help in measuring different parameters of air quality. 

The PCBA recently inaugurated a continuous air quality monitoring station in Guwahati, the first-of-its kind in Northeast. Officials informed G Plus that the real-time data which is generated is reflected on display boards in two different places in Guwahati.
