WHAT IS aIR QUality AND HOW DO WE MEASURE IT?

---

Air quality is a major concern for many countries around the world. The  Air Quality Index (AQI) is a tool used to measure the amount of pollutants in the air and to help determine the safety of breathing it in. This index is used to inform residents of the air quality in their area, and how it affects their health.  The AQI ranges from 0 to 500, with higher numbers indicating worse air quality. The AQI is broken up into six categories: 

1. Good (0-50), Moderate (51-100)
2. Unhealthy for Sensitive Groups (101-150)
3. Unhealthy (151-200)
4. Very Unhealthy (201-300)
5. Hazardous (301-500)

Each category corresponds to a different level of pollution, and a different potential risk to lung health.   

Good air quality (0-50) is considered safe for everyone and poses no risk to lung health. However, air quality in the Moderate (51-100) and Unhealthy for Sensitive Groups (101-150) categories can cause health problems for those with lung or heart disease, the elderly, and children. People in these groups should limit the amount of time spent outdoors in areas with air quality in this range. 

Air quality in the Unhealthy (151-200) and Very Unhealthy (201-300) categories can cause serious health problems for everyone. People should avoid outdoor activities in these areas and stay indoors as much as possible.   

Finally, air quality in the Hazardous (301-500) category is extremely dangerous and can cause serious health problems for everyone, even healthy adults. People should not be outside in these areas.  

The AQI is an important tool for people in the Gambia to be aware of the air quality in their area and to understand the potential risks to their health. By being aware of the AQI, people can make informed decisions about their health and safety.
