Air quality in Singapore's central region has slipped back into the unhealthy range, marking a deterioration in conditions across the city-state's core areas. The 24-hour PSI reading for the central region reached 104, crossing the threshold that signals unhealthy air quality levels.
Meanwhile, air quality in the northern, southern, eastern and western regions of Singapore remained within the moderate range as of 8pm, according to the latest monitoring data. The divergence in readings across different zones suggests localised pollution sources or atmospheric conditions affecting the central region more acutely.
The PSI is Singapore's primary air quality indicator, with readings above 100 classified as unhealthy, particularly for vulnerable groups including children, the elderly and individuals with respiratory or heart conditions. Authorities typically recommend that residents in affected areas limit outdoor activities and use air purifiers indoors during periods of unhealthy air quality.
The development comes as Singapore continues to monitor transboundary haze and local pollution sources that periodically affect air quality across the island. Residents are advised to check the National Environment Agency's real-time PSI updates for the latest air quality information in their areas.
