Understanding Air Quality and the AQI
Air quality is determined by the presence and concentration of pollutants in the air. The Air Quality Index (AQI) helps to measure these pollutants and communicate their impact on health.
Components of Air Quality
Air quality is influenced by various pollutants. PM2.5 and PM10 are tiny particles that can be harmful when inhaled. PM2.5 particles are smaller than 2.5 micrometers while PM10 are particles up to 10 micrometers. These can come from sources like vehicle exhaust, industrial emissions, and wildfires.
Ozone is another key component, formed when sunlight reacts with pollutants like nitrogen oxides. High levels can cause respiratory issues. Nitrogen dioxide is a gas from burning fossil fuels. It can irritate airways and reduce lung function.
Sulfur dioxide, produced by burning coal or oil at power plants, can also cause respiratory problems. Lastly, carbon monoxide comes from incomplete combustion and can reduce oxygen delivery in the body, causing cardiovascular issues.
Interpreting the Air Quality Index (AQI)
The AQI is a scale used to report air quality. It ranges from 0 to 500. Lower values mean better air quality. The scale is divided into six categories:
0-50: Good
51-100: Moderate
101-150: Unhealthy for Sensitive Groups
151-200: Unhealthy
201-300: Very Unhealthy
301-500: Hazardous
Each pollutant has its own concentration that corresponds to these categories. For instance, PM2.5 levels above a certain threshold will push the AQI into the unhealthy range. Understanding this helps people make informed decisions about outdoor activities.
