Singapore's air quality showed signs of improvement on Tuesday, with the majority of monitoring stations recording normal one-hour PM2.5 concentrations across the island. The positive trend marked a shift from earlier pollution concerns that had affected parts of the city-state.
However, the longer-term air quality picture remained less encouraging. The 24-hour Pollutant Standards Index, or PSI, stayed at unhealthy levels in the western and central regions at 3pm, indicating that pollution concentrations had not yet sufficiently dissipated over the full day-long measurement period.
The improvement in hourly PM2.5 readings suggested that immediate air quality conditions were stabilising, though residents and authorities continued to monitor developments in the affected zones. Air quality fluctuations are not uncommon in Singapore during certain periods, influenced by meteorological conditions and regional atmospheric patterns.
The National Environment Agency continues to track air quality across all monitoring stations islandwide, providing real-time updates to the public through its official channels.
