4 Αυγ 2018 · The Air Quality Index (AQI) is a measurement of air pollutant concentrations in ambient air pollution and their associated health risks. Air pollutants measured in AQI. There are six air pollutants measured in the index formula, including: PM2.5; PM10; carbon monoxide; sulfur dioxide; nitrogen dioxide; ground-level ozone
The Ministry of Environment of South Korea uses the Comprehensive Air-quality Index (CAI) to describe the ambient air quality based on the health risks of air pollution. The index aims to help the public easily understand the air quality and protect people's health.
The U.S. Air Quality Index (AQI) is EPA's tool for communicating about outdoor air quality and health. The AQI includes six color-coded categories, each corresponding to a range of index values. The higher the AQI value, the greater the level of air pollution and the greater the health concern.
What is the Air Quality Index (AQI)? The AQI is a numerical scale that quantifies the level of air pollution in a specific area at any given time. It takes various air pollutants into account, including particulate matter (PM2.5 and PM10), ground-level ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO).
22 Σεπ 2022 · The greater the density of pollutants in the air, the higher the Air Quality Index (AQI), a scale that runs from zero to 500. An AQI of 50 or below is considered safe, while readings above 100 are deemed unhealthy.
19 Νοε 2018 · AQI focuses on the air quality and related health concerns. Many countries have their own AQI standards and scales. For example, the US AQI index ranges from 0–500. The higher the AQI value, the greater the level of air pollution and the greater the health concern.
The table below defines the Air Quality Index scale as defined by the US-EPA 2016 standard: For more information about the pollutants included in the AQI scale, please refer to: PM 2.5 instant-cast scale. Understanding PM 10 vs PM 2.5. Ozone (O 3) AQI scale. Nitrogen Dioxide (NO 2) scale.
