Air quality across the country remained in the moderate range yesterday, with the Pollution Standards Index (PSI) readings fluctuating throughout the day across the four districts.
The Department of Environment, Parks and Recreation (JASTRe) recorded moderate air quality at 7am, 9am, 11am, 2pm and in the final reading at 4pm.
At 4pm, Brunei-Muara recorded the highest PSI reading at 69, followed by Tutong at 57, Belait at 56 and Temburong at 51.
The fluctuating readings throughout the day saw all four districts remain within the moderate air quality range in the recorded periods.
Meanwhile, JASTRe, Ministry of Development, steps up monitoring during the hazy period with air quality reporting in Brunei Darussalam over the past weeks has been enhanced with the inclusion of PM2.5 concentrations in the Pollutant Standards Index (PSI), which took effect last September 1.
PM2.5 refers to fine suspended particulate matter measuring less than 2.5 micrometres in diameter, as defined by the World Health Organization (WHO) where these fine particles can penetrate deep into the lungs and enter the bloodstream, potentially causing adverse effects on the cardiovascular and respiratory systems.
JASTRe will continue to closely monitor air quality nationwide and issue PSI updates five times daily during the hazy period.
PSI reading below 50 is Good, PSI between 51 and 100 is Moderate, PSI between 101 and 200 is Unhealthy, PSI between 201 and 300 is Very Unhealthy while PSI above 300 is Hazardous.
The Ministry of Health has advised members of the public to take precautions when PSI readings reach the Unhealthy level and public are 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 immediately contact the Fire and Rescue Department at 995 in the event of bush or forest fires and public members are 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.
