SINGAPORE: Air quality is expected to remain unhealthy in Singapore on Wednesday (Oct 14), said the National Environment Agency (NEA) in its haze advisory on Tuesday evening.
Air quality has stayed in the unhealthy range across Singapore on Tuesday, while hourly PM2.5 levels ranged from normal to elevated through the day.
At 7pm, 24-hour Pollutant Standards Index (PSI) readings were unhealthy across Singapore, ranging from 111 to 160.
The 1-hour PM2.5 readings were in the elevated band in all regions, ranging from 57 to 95, after PM2.5 levels in the northern region returned to the elevated range.
In its update, NEA said moderate to dense smoke plumes were observed from fires in Kalimantan and southern Sumatra.
"Smoke haze was observed drifting towards Singapore under the prevailing southeasterly winds," it said.
According to the agency, haze could continue drifting towards Singapore due to prevailing easterly or southeasterly winds and expected dry conditions over parts of southern Sumatra and Kalimantan.
"The 24-hr PSI for Singapore is forecast to be in the unhealthy range," it said.
When the 24-hour PSI falls within this range, those who are healthy are advised to reduce prolonged or strenuous outdoor physical exertion.
Vulnerable groups such as the elderly, pregnant women and children should minimise such activities, while people with chronic lung or heart disease should avoid them.
NEA had said on Monday that it is "closely monitoring" the haze situation and gathering information on hotspots and their sources, as earlier investigations under the Transboundary Haze Pollution Act remain ongoing.
Subsidised treatments for haze-related conditions became available in Public Health Preparedness Clinics (PHPCs) and polyclinics on Monday as well, following an announcement by Health Minister Ong Ye Kung the day before.
All Singaporeans will be eligible for subsidies at polyclinics, while eligibility at participating PHPCs will be limited to certain groups such as children and seniors.
