Ilmanlaatuindeksihin
Ilmanlaatuindeksihin (Air Quality Index, AQI) are numerical scales used to communicate the air quality in a specific area. They are designed to make complex air quality data more accessible and understandable to the public. AQI values are typically calculated based on the concentrations of various pollutants, such as particulate matter (PM2.5 and PM10), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO). Each pollutant has its own health-based standard, and the AQI is determined by the pollutant with the highest concentration relative to its standard.
The AQI is usually categorized into different levels, each with a corresponding color code and health advisory.
Ilmanlaatuindeksihin are used by governments, environmental agencies, and health organizations to monitor and report air quality.
The calculation of AQI values can vary slightly depending on the region and the specific pollutants considered.
