Central Singapore's air quality deteriorated markedly on Tuesday as the Pollutant Standards Index climbed to 102, crossing into the unhealthy category and raising concerns among residents and health officials.
The reading marks a significant shift from recent conditions, with the central region experiencing notably worse air quality than other parts of the island. In contrast, the northern, southern, eastern and western zones all maintained readings within the moderate range, suggesting the pollution concentration was geographically concentrated.
A PSI reading between 101 and 200 is classified as unhealthy, potentially affecting members of the general public and posing particular risks to individuals with respiratory conditions or heart disease. The National Environment Agency has not issued specific health advisories, though residents in affected areas are typically advised to limit prolonged outdoor activities.
The spike in central Singapore's PSI comes amid seasonal variations in air quality. Authorities continue to monitor atmospheric conditions closely, and residents are urged to check real-time PSI updates on official government platforms for their specific locations.
