Singapore's air quality has deteriorated significantly, with pollutant readings rising into the unhealthy range across multiple regions of the island. The National Environment Agency recorded a 24-hour PSI reading of 163 in the central region at 7am on Wednesday, indicating unhealthy air conditions for the general population.
PSI readings in the 151-200 range are classified as unhealthy, posing health risks particularly to vulnerable groups including young children, the elderly, and individuals with respiratory or cardiovascular conditions. Members of the general public may also experience health effects at this level of air pollution.
The upward trend in PSI readings suggests worsening atmospheric conditions across the island. Residents have been advised to monitor air quality updates regularly and take appropriate precautions, including limiting outdoor activities and using air filtration masks if necessary.
The exact sources contributing to the current haze episode remain under investigation. Singapore has historically experienced transboundary haze pollution during certain seasons, though authorities continue to assess real-time air quality data to determine contributing factors.
