Air quality in western Singapore deteriorated overnight, with particulate matter concentrations climbing into the high range. One-hour PM2.5 readings hit 171 micrograms per cubic meter, according to monitoring data.
PM2.5 refers to fine particulate matter measuring 2.5 micrometers or smaller in diameter. These particles are small enough to penetrate deep into the respiratory system and are commonly associated with transboundary haze and industrial emissions.
The National Environment Agency classifies air quality based on the Pollutant Standards Index, with readings in the high range posing potential health risks for sensitive groups including children, the elderly, and individuals with respiratory or cardiovascular conditions.
The overnight pollution spike underscores Singapore's vulnerability to air quality fluctuations, particularly during periods when meteorological conditions and regional emissions align unfavorably. Residents in affected areas were advised to monitor air quality updates and take precautionary measures.
