As residents of Singapore, staying informed about air quality is essential for our health and well-being. The current PSI (Pollutant Standards Index is a critical indicator that informs us about the air quality levels in our environment. This article provides an update on the current PSI in Singapore for June 2024, helping you understand what it means for your daily activities.
Key Takeaways
- The PSI level indicates the quality of air, affecting health and daily activities.
- A PSI reading above 100 indicates unhealthy air quality, while readings above 200 signify hazardous conditions.
- Staying updated on the current PSI can help you make informed decisions for outdoor activities.
Understanding the PSI Levels
What is PSI?
The Pollutant Standards Index (PSI) measures air quality based on the concentration of various pollutants, including:
- PM10 (Particulate Matter): Particles with a diameter of 10 micrometers or smaller.
- PM2.5 (Fine Particulate Matter): Smaller particles that can penetrate deep into the lungs.
- Nitrogen Dioxide (NO2): A gas produced from vehicle emissions and industrial activities.
- Sulfur Dioxide (SO2): Emitted from burning fossil fuels.
PSI Categories
The PSI is categorized into different levels, each indicating varying degrees of health impact:
- Good (0-50): Air quality is considered satisfactory.
- Moderate (51-100): Air quality is acceptable; however, there may be a concern for some people.
- Unhealthy (101-200): Everyone may begin to experience health effects, and members of sensitive groups may experience more serious effects.
- Very Unhealthy (201-300): Health alert; everyone may experience more serious health effects.
- Hazardous (301 and above): Serious health effects for the entire population.
