Air pollution is a health and environmental issue that affects all countries. Air quality monitoring is the process of gathering and measuring air pollution samples. The data from these samples can be used to: Compare the air's state to clean air standards Compare the air's state to historical air quality levels Compare the air's state to data on health and environmental impacts Identify pollution sources Monitor climate change Support research and development  Air quality is measured using the Air Quality Index (AQI), which is a scale that runs from 0 to 500. The higher the AQI... Show more
