Air quality across several parts of Sri Lanka has deteriorated to unhealthy levels due to a combination of local emissions and transboundary pollution drifting from neighbouring countries, including India, experts warn.

According to the Air Quality Index (AQI), affected areas include Kaduruwela, Chilaw, Digana, Hungama, Akkaraipattu, Kalawana, Jaffna, and parts of Colombo.

The National Building Research Organisation (NBRO) said the situation is expected to persist until March 2026, posing health risks to children, the elderly, and individuals with respiratory issues.

Authorities advise the public to limit outdoor activity, keep windows closed, and wear masks when outdoors.

India continues to battle a severe smog crisis, with New Delhi’s AQI reaching hazardous levels and residents protesting for urgent government action.
