Air quality across Singapore has deteriorated significantly, with the Pollution Standards Index (PSI) entering unhealthy territory in multiple regions. The central area has been experiencing unhealthy PSI levels since 1pm on September 19, with eastern and western regions subsequently recording similarly elevated readings.
The expansion of poor air quality across the island marks a notable shift in atmospheric conditions, affecting residents in all major areas of Singapore. The unhealthy PSI classification indicates that members of the general public may begin to experience health effects, with vulnerable groups such as children, the elderly, and those with respiratory conditions particularly at risk.
Authorities have not specified the duration for which elevated PSI levels are expected to persist. Residents are typically advised to limit outdoor activities and consider using air purifiers indoors when PSI readings reach unhealthy ranges. Real-time PSI data is available through official channels for those monitoring air quality in their specific regions.
The simultaneous degradation of air quality across eastern, central, and western zones suggests widespread atmospheric conditions contributing to the haze, likely linked to transboundary pollution patterns common in the region during certain periods.
