Haze and it’s impact on Singapore
Singapore’s air quality has dipped into the unhealthy range as southeasterly winds blow smoke haze from forest and peatland fires in Kalimantan, Indonesia, towards Singapore. The National Environment Agency (NEA) forecasts the 24-hour PSI to range between 110 and 180.
Particle Types and Sources
• PM2.5 (Fine Particles):
Microscopic soot, ash, and carbon compounds that stay suspended for long periods and travel long distances.
• PM10 (Coarser Particles):
Dust, dirt, and larger smoke debris.
• Gases:
Carbon monoxide, sulfur dioxide, and nitrogen oxides mixed with the particulate cloud.
• Regional Origin:
Driven by transboundary smoke from fires in Sumatra and Kalimantan carried by prevailing winds.
Health and Environmental Impacts of Haze
• Deep Lungs Penetration:
PM2.5 bypasses nose and throat defenses, entering deep lung air sacs and the bloodstream.
• Symptoms:
Causes eye, nose, and throat irritation, coughing, wheezing, and aggravated asthma or bronchitis.
• Vulnerable Groups:
Children, the elderly, pregnant women, and people with pre-existing heart or lung conditions face higher risks.
• Visiblity:
Scatters sunlight to reduce horizontal visibility and create a grey or brownish sky.
The Right First Aid Face Mask that can filter off the Particles found in Haze
Haze consists of microscopic solid and liquid particles suspended in the air, primarily fine particulate matter like PM2.5 (particles 2.5 micrometers or smaller) and PM10. These particles originate from regional forest and peatland fires, agricultural open burning, vehicle emissions, and industrial smoke.
When haze levels are elevated, wear a well-fitting N95, KN95, or equivalent respirator—especially outdoors or if you have asthma or other respiratory conditions. A regular surgical mask provides limited protection against fine haze particles. Check Singapore’s official Pollutant Standards Index (PSI) before heading outside, reduce strenuous outdoor activity, and seek medical attention if you experience breathing difficulty or chest pain.
