Sri Lanka, Dec. 22 -- Air quality across Sri Lanka continues to remain slightly unhealthy, according to real-time Air Quality Index (AQI) data.

Several areas, including Kaduruwela, Chilaw, Akaragama, Wanduragala, Digana, Madampagama, Hungama, Akkaraipattu, Kalawana, Mulliyawalai, Pannankandy, Adampan and Uppuveli, along with parts of Jaffna and Colombo, have recorded slightly unhealthy air quality levels.

A senior official at the National Building Research Organisation (NBRO) told Daily Mirror that the decline in air quality is mainly due to local pollution sources combined with prevailing atmospheric conditions that limit the dispersion of pollutants.

The official said the situation is expected to persist until around March next year....
