INDORE: The incessant rain seems to have cleared the air by reducing toxic air pollutants, according to officials of regional pollution control board. Over 11 inches of rainfall in last few days have not only tamed the scorching heat but also the air pollutants, pollution control board officials claimed.According to regional PCB officials, rain recorded recently helped PM10 and PM2.5 particles reduce by around 25% providing respite from air pollution apart from bringing the temperature down.The air quality results have been released by taking samples from four air quality monitoring systems situated in localities and comparing the level of PM10 and PM2.5.In June, the air quality monitoring system installed in Vijay Nagar had recorded 82 units of PM10 and 37 units of PM2.5 that has respectively reduced to 69 and 34 as data compiled by PCB on Sunday.Similarly, the system installed at Sanwer Road (90 units of PM10, 43 units of PM2.5), Kothari Market (84 units of PM10, 39 units of PM2.5) and DIG office at Regal Square had recorded 86 units of PM10 and 23 units in the month of June.“The rains have helped in checking fog and dust in the air and have resulted in improving air quality. At air quality monitoring system, the pollution level has now recorded as 72 units of PM10 and 38 units of PM2.5 at Sanwer Road, 56 units of PM10 and 25 units of PM2.5 at Kothari Market and 55 units of PM10, 19 units of PM2.5 at DIG office at Regal Square,” chief chemist and lab head at regional PCB Dr DK Wagela told TOI.He added that the monitoring system installed at Sanwer Road, Vijay Nagar and Kothari Market will soon show real-time air quality of the areas. “According to data, Sanwer Road Industrial Area is most polluted while air quality is comparatively better at Regal Square,” Dr Wagela said while talking to TOI.
