The intense lockdown, forced by the second wave of the Covid-19 pandemic, led to a reduction in vehicular movement and a slight improvement in the air quality in Kathivakkam near Ennore, Kodungaiyur, Royapuram, Koyambedu and Perungudi, say Tamil Nadu Pollution Control Board (TNPCB) authorities. In Manali, the quality was ‘moderate’.
