The air quality index is measured in this way
There are eight standards for measuring air pollution (pollutants PM2.5, PM10, carbon monoxide, ozone, sulfur dioxide, aluminum and lead). The most important are PM 2.5 and PM 10. These are the highest numbers. PM2.5, PM10 and any other standard are included when measuring the air quality index. It only has standard, it has no unit of measurement. PM2.5 and PM10 are measured in micrograms per cubic meter. The pollution caused by burning anything consists of PM 2.5 and PM-10 in dust particles.
