Haze in Singapore: Air quality unhealthy across the island

Singapore's air quality remained unhealthy as of October 10, according to the 24-hour Pollutant Standards Index. The PSI readings were elevated across all five regions - north (125), south (141), east (157), west (162), and central (176). The National Environment Agency (NEA) had previously forecasted the PSI for the following day to fall within the "unhealthy to low very unhealthy range".

Those with healthy lungs were advised to limit prolonged or strenuous outdoor activities, while vulnerable individuals, such as the elderly, pregnant women, children, and those with chronic lung or heart disease, were instructed to avoid outdoor activities altogether. The government's haze task force prepared measures should the PSI reach the very unhealthy range, including the distribution of N95 masks and modifications to school lessons and outdoor activities.
