Haze Returns to Singapore: Health Concerns Amidst Normal Air Quality Readings
3/27/2026, 9:56:42 AM
Current Situation and Health Implications
In recent weeks, residents of Singapore have reported a persistent burning smell in the air, particularly noticeable during evening hours. Cindy, a 33-year-old resident of Telok Blangah, expressed her concerns about the worsening air quality, especially as a parent. Many Singaporeans share similar worries, noting that the fogginess and burning odor seem to have intensified over the past year. Despite these concerns, the National Environment Agency (NEA) has indicated that air quality measurements, including the 24-hour Pollutant Standards Index (PSI) and PM2.5 levels, remain within the good to moderate range.
Causes of the Burning Smell
The NEA attributes the burning smell primarily to transboundary haze resulting from forest and peat fires in the region. These fires release volatile organic compounds (VOCs), which can be detected by the human nose at very low concentrations. Dr. Steve Yim, a professor of environmental health at Nanyang Technological University, explained that peat fires, particularly those with insufficient oxygen, produce a higher volume of odorous gases due to smoldering.
Nighttime Intensification and Geographic Variability
The smell tends to be more pronounced at night due to weaker winds that prevent the dispersion of air pollutants. Cooler temperatures during the evening also contribute to this phenomenon. Additionally, residents in eastern Singapore have reported stronger odors, which Dr. Koh Tieh Yong from the National University of Singapore attributes to prevailing winds carrying lighter VOCs from nearby Johor, Malaysia, where moderate haze was detected.
Health Precautions and Rising Health Issues
Medical professionals have noted an increase in cases of eye, nose, and throat irritation among patients, with some experiencing asthma attacks after long periods of stability. Dr. Kenneth Tan and Dr. Elaine Chua have observed a rise in throat complaints and asthma incidents, although a direct link to the burning smell remains unclear. They advise individuals, especially those with allergies or respiratory conditions, to take precautions beyond relying solely on PSI readings. Recommendations include using preventive inhalers, nasal steroids, and air purifiers to alleviate discomfort.
Official Statements and Community Response
The NEA has reiterated that the gases causing the burning smell are distinct from the pollutants monitored for air quality. As the situation continues, environmentalists are urging regional cooperation to address the underlying causes of transboundary haze. The community remains vigilant, balancing health concerns with the current air quality data, as they seek solutions to mitigate the impact of seasonal haze.
Verbatim Quotes
- “I always keep our windows closed, which is not very good for our health because we need fresh air. But it’s impossible to get fresh air nowadays.” — Cindy, Resident
- “The amount of allergens in the air does not have to be high to trigger an allergic reaction.” — Dr. Elaine Chua, Medical Professional
- “When the winds are weaker, the air pollutants are not diluted and dispersed as quickly as in the day.” — NEA Statement
This ongoing situation highlights the complexities of air quality management in Singapore, where environmental factors and public health intersect, necessitating a multifaceted approach to address both immediate concerns and long-term solutions.
