Hyderabad’s air quality drops post lockdown

Hyderabad: Due to resumption of business activities and increase in vehicular traffic after the lifting of lockdown in Telangana, Hyderabad’s air quality has dropped as pollution increased significantly.

After the imposition of the lockdown in the state, the air quality improved from ‘moderate’ to ‘good’. However, as soon as the lockdown lifted, the quality again dropped. The similar trend was also witnessed during the lockdown imposed last year.

As per Telangana Pollution Control Board’s data, the air quality index (AQI) during most of the days in the month of March and April was ‘moderate’. After the imposition of lockdown on May 12, AQI improved to ‘good’. The index again dropped ‘moderate’ after removal of restrictions, New Indian Express reported.
