Singapore is experiencing a slight improvement in overall air quality, according to the National Environment Agency. However, concerns remain as 1-hour PM2.5 readings are currently elevated in two unspecified regions within Singapore. The agency forecasts the 24-hour PSI – the Pollutant Standards Index – to range between 110 and 180 on Wednesday. These levels indicate moderate to unhealthy air quality for sensitive groups. Residents, particularly those with respiratory conditions, are advised to reduce prolonged or strenuous outdoor activities. The National Environment Agency continues to monitor the situation and will provide further updates as needed regarding air quality in Singapore. Further details regarding the specific regions experiencing elevated PM2.5 are currently unavailable.
