Air quality has declined noticeably in several parts of the island, the National Building Research Organisation (NBRO) said, citing recent monitoring data.
According to the NBRO, the Air Quality Index (AQI) in a number of districts, including Colombo and Gampaha, has risen to levels deemed unhealthy for sensitive groups.
In response, health authorities have issued a special advisory urging high-risk individuals—such as young children, pregnant women, the elderly, and those with respiratory conditions—to remain alert and take necessary precautions to safeguard their health.
