There are eight standards (pollutants PM 2.5, PM 10, carbon monoxide, ozone, sulfur dioxide, aluminum and lead) to measure air pollution. The most important in this are PM 2.5 and PM 10. These numbers are the highest. PM 2.5, PM 10 and any other parameters are taken into account when measuring the Air Quality Index. It has only standard, it has no measurement unit. At the same time, PM 2.5 and PM 10 are measured in micrograms per cubic meter. The pollution caused by burning of anything contains PM 2.5 and dust particles contain PM-10.
