NBRO Warns of Possible Deterioration in Air Quality Across Sri Lanka

Sri Lanka’s air quality remained largely at moderate levels across major cities over the past 24 hours, though conditions could worsen in some areas in the coming days, according to the National Building Research Organisation (NBRO).

The NBRO said particulate matter (PM2.5) levels were moderate in most urban centres. Good air quality was recorded in Vavuniya, Nuwara Eliya, Embilipitiya, Trincomalee, Mullaitivu, Batticaloa and Monaragala.

However, forecasts for the next 24 hours indicate that air quality may range from moderate to slightly unhealthy in several cities, including Jaffna and Puttalam. The NBRO warned that polluted winds originating from the northern region under transboundary conditions could lead to slightly unhealthy air quality levels across the country over the next two to three days.

The public has been advised to wear face masks when possible, while sensitive groups, including those with respiratory conditions, are urged to seek medical advice if they experience breathing difficulties.

Air quality in Sri Lanka is assessed using the Sri Lanka Air Quality Index, which categorises conditions from good to hazardous based on particulate matter concentrations.
