The lockdown to curtail the spread of covid pandemic has resulted in fall in pollution level and improvement in air quality across Haryana.
The air quality index (AQI) has dropped to good from satisfactory levels in majority of the cities of the state, while to satisfactory level from moderate and poor quality levels in remaining cities.
A Haryana State Pollution Control Board (HSPCB) report, compiled between March 21 (day before “Janta Curfew”) and March 28 (fourth day after lockdown), indicates pollution levels have plummeted due to reduction in vehicular traffic, shutdown of industries across the state and people are breathing relatively cleaner air.
In the wake of Covid pandemic, Prime Minister Narendra Modi had urged people for “Janta Curfew” for March 22, and declared a lockdown of 21 days from midnight of March 24/25.
