Air quality in central Singapore deteriorated Monday morning, with the Pollution Standards Index (PSI) reaching 104 at 9am. This reading signifies an “unhealthy” range, prompting concerns about public health. The increase is attributed to ongoing haze conditions affecting the region. While the overall PSI remains varied across the island, central Singapore is currently experiencing the most significant impact. Residents, particularly those with respiratory conditions, are advised to take precautions. The National Environment Agency has not yet issued specific advisories beyond monitoring the situation closely. Further updates on air quality will be provided as the situation evolves.
