Expat guide to air quality in Singapore
Understanding Air Quality in Singapore
Singapore experiences varying air quality levels throughout the year, influenced by several factors such as industrial activities, vehicular emissions, and seasonal changes. Among these, the most significant contributor to poor air quality is the transboundary haze, primarily resulting from land and forest fires in neighbouring countries, particularly during the dry season.
Air Quality Index (AQI)
Singapore uses an Air Quality Index (AQI) to communicate air quality levels to the public. The AQI is categorised into several ranges:
Good (0-50): Air quality is considered satisfactory, and air pollution poses little or no risk.
Moderate (51-100): Air quality is acceptable; however, for some pollutants, there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for Sensitive Groups (101-150): Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy (151-200): Everyone may begin to experience health effects, and members of sensitive groups may experience more serious health effects.
Very Unhealthy (201-300): Health alert; everyone may experience more serious health effects.
Hazardous (301 and above): Health warnings of emergency conditions. The entire population is more likely to be affected.
Monitoring stations across Singapore provide real-time updates on the AQI levels, enabling residents to stay informed.
Monitoring Air Quality
As an expat, staying updated on air quality is crucial, especially if you have pre-existing health conditions or are particularly sensitive to pollutants. The National Environment Agency (NEA) of Singapore operates an official website and mobile application that allow you to check current AQI levels and receive alerts on significant changes.
Mitigating Exposure
During periods of poor air quality, consider the following tips to minimise your exposure:
Stay Indoors: Limit outdoor activities, particularly strenuous exercises, during high AQI periods. Keep windows and doors closed to reduce indoor pollution.
Use Air Purifiers: Investing in a good quality air purifier can help improve indoor air quality by filtering out pollutants.
Wear Masks: High-efficiency masks can provide some protection when going outdoors during unhealthy air quality days.
Monitor Updates: Regularly check the air quality and heed advisories from health authorities, especially during haze events.
Seasonal Variations
In Singapore, air quality can fluctuate seasonally. The haze typically peaks between June and October due to dry weather in the region. During this time, residents should remain particularly vigilant since the impact can be felt more acutely.
Health Considerations
Long-term exposure to poor air quality may have health implications. It is advisable for expats with respiratory issues, heart conditions, or other health concerns to consult with a medical professional regarding appropriate precautions.
Singapore guide
Being aware of air quality levels and understanding how to respond to them can help expats navigate life in Singapore more comfortably. By staying informed and taking necessary precautions, you can minimise the impact of poor air quality on your health and quality of life.
