Singapore air quality deteriorates as PSI approaches unhealthy levels

Singapore's air quality has taken a turn for the worse, with the Pollutant Standards Index approaching levels deemed unhealthy for the general population, particularly in the central region of the island-state.

The National Environment Agency, which monitors atmospheric conditions across the country, said it is keeping a watchful eye on developments and remains prepared to issue further guidance if conditions deteriorate.

Residents and commuters in central Singapore should be prepared for occasional periods of haze that may reduce visibility and air quality over the coming days, the agency indicated. Such episodes are not unusual during certain seasons and can stem from various atmospheric factors affecting the region.

The agency typically advises members of the public to check real-time PSI readings for their specific locations, as air quality can vary significantly across different parts of the island. Those in sensitive groups, including children, elderly persons, and individuals with respiratory conditions, are generally advised to limit prolonged outdoor activities when air quality deteriorates.

Singaporeans are encouraged to monitor official updates from the National Environment Agency for the latest air quality information and any health advisories that may be issued.
