Air quality across all four districts was moderate as of 4pm yesterday, with the Tutong District recording the highest Pollutant Standards Index (PSI) reading of 79, followed by the Brunei-Muara District at 72. The Temburong District recorded a PSI reading of 68, while Belait recorded 63.
A PSI reading below 50 is considered good, while readings between 51 and 100 are moderate, 101 and 200 are unhealthy, 201 and 300 are very unhealthy, and above 300 are hazardous.
Over the past weeks, air quality reporting in the Sultanate has been enhanced with the inclusion of PM2.5 concentrations in the PSI, as the Department of Environment, Parks and Recreation (JASTRe), Ministry of Development, steps up monitoring during the hazy period.
PM2.5 refers to fine suspended particulate matter measuring less than 2.5 micrometres in diameter, as defined by the World Health Organization.
These fine particles can penetrate deep into the lungs and enter the bloodstream, potentially causing adverse effects on the cardiovascular and respiratory systems.
JASTRe said it will continue to closely monitor air quality nationwide and issue PSI updates daily during the hazy period, at 7am, 9am, 11am, 2pm and 4pm.
The Ministry of Health (MoH) advised the public to take precautions when PSI readings reach an unhealthy level.
The public is advised to reduce strenuous or prolonged outdoor activities and minimise unnecessary exposure to haze. Children, older persons and pregnant women are advised to restrict strenuous or prolonged outdoor activities, while individuals with existing heart or respiratory conditions are advised to avoid such activities.
Those experiencing persistent or worsening symptoms, including coughing, wheezing, shortness of breath, chest discomfort or difficulty breathing, are advised to seek medical attention at the nearest health centre or health facility.
Meanwhile, the public is reminded to contact the Fire and Rescue Department at 995 in the event of bush or forest fires. The public is also urged to refrain from open burning and other activities that could worsen haze conditions during the dry period.
For complaints regarding open burning activities, or for health information and advice, the public may contact the Darussalam Hotline 123. Further information on PSI readings is available through JASTRe and its official Instagram account while health information and advice are available through the MoH and its official Instagram page.
