The nationwide curfew to combat the coronavirus outbreak has directed a significant reduction in pollution in Sri Lanka, according to the officials. As a result of travel restrictions and shutting down of non-essential activities such as industries, construction activities, biomass burning and residential activities, air and water quality improvement have been noted in many cities, mainly Colombo and Kandy. Air quality monitor of the US Embassy has reported that the air quality was 96% in Colombo on 30/03/2020.
Central Environmental Authority (CEA) has been stated that the quality of the water in the Kelani river has risen thanks to the decline in industrial effluents being released to waterways. Also, they have reported that the turbidity levels of water in the Kelani River, which cuts across five districts, had remained positive, unlike any other period in recent previous years.
