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 value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality. Air pollutants can be manually analyzed using a variety of methods, including: - Spectrometry, such as absorption spectrophotometry, atomic absorption spectrometry, and ICP emission method - Chromatography, such as gas chromatography and liquid chromatography Some techniques used for measuring air pollutants include: Ozone: Ultraviolet spectroscopy Oxides of nitrogen: Chemiluminescence Sulfur dioxide: Pulsed fluorescent spectrophotometry Carbon monoxide: Infrared spectrometry Show less
