B Anbuselvan By Express News Service CHENNAI: The poor air quality in Chennai over the last few days was due to multiple factors including low moisture in sea breeze and reduction in cloud cover, said Revenue and Disaster Management Department minister R Udayakumar on Monday. This was the first official confirmation on the unprecedented drop of air quality in the city since November 4. “Of the 8 air quality monitoring stations in the city, only in two stations AQI recorded between 202 and 300 (which was catergorised as poor) and an expert committee has been constitued to find the cause,” he said.

Allying the fears over health complaints due to low air quality, Udayakumar claimed that the health department so far have not received any respiratory complainants and the situation being monitored by Tamil Nadu Pollution Control Board, Disaster Management and health department round the clock, he said.
