BANDAR SERI BEGAWAN: Haze conditions worsened across Brunei Saturday morning (Sept 5), with all four districts recording unhealthy air quality as Pollutant Standards Index (PSI) readings rose above 100.
At 9am, Brunei-Muara recorded the highest PSI at 155, followed by Belait at 164, Temburong at 104 and Tutong at 123.
The latest readings mark a deterioration in Temburong, which recorded a moderate PSI of 96 at 7am.
The Department of Environment, Parks and Recreation (JASTRe) said air quality reporting has been enhanced since September 1 through the incorporation of PM2.5 concentrations into PSI reporting.
PM2.5 refers to fine particulate matter smaller than 2.5 micrometres that can penetrate deep into the lungs and enter the bloodstream, potentially affecting the cardiovascular and respiratory systems.
JASTRe is monitoring air quality nationwide and issuing PSI updates five times daily at 7am, 9am, 11am, 2pm and 4pm during the hazy period.
With PSI readings between 101 and 200 classified as unhealthy, the Ministry of Health advised the public to reduce strenuous or prolonged outdoor activities and avoid unnecessary exposure to haze.
Children, older persons and pregnant women should restrict strenuous or prolonged outdoor activity, while people 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 should seek medical attention at the nearest health centre or health facility.
The public is also reminded to refrain from open burning during the dry period. - Borneo Bulletin/ANN
