The Daily Air Quality Index (DAQI) tells you about levels of air pollution and provides recommended actions and health advice. The index is numbered 1-10 and divided into four bands, low (1) to very high (10), to provide detail about air pollution levels in a simple way, similar to the sun index or pollen index.

There are six air pollutants measured in the index formula, including: 1. PM2.5 2. PM10 3. carbon monoxide 4. sulfur dioxide 5. nitrogen dioxide 6. ground-level ozone An AQI number is assigned based on the air pollutant with the highest AQI number at the moment the air quality is measured. Only pollutants available from a given air quality monitori...
Here’s how each of the AQI categories are represented, how they can impact human health, and some recommendations for what to do when the AQI has reached a higher category. The categories are listed from least harmful to human health (“good”) to the most harmful (“hazardous”).
There are different systems used around the world for measuring air quality. The United States and China AQI systems are the most widely used systems – both measure the same group of air pollutants. However, each system rates AQI scores from 200 and lower differently.2 The U.S. AQI system generally yields higher scores for AQI under 200 because low...
The air quality index reinterprets potentially complex air quality data into a meaningful number with corresponding categories of pollutant concentrations and associated health effects. Please note, though, that there is no safe level of air pollution, in particular as the AQI reaches closer to 50 and beyond. By knowing whether the air we breathe i...
The DAQI bands air quality levels along a scale of 1-10, which corresponds to different health hazard warning related to air pollution levels, where 1-3 is ‘Low’, 4-6 is ‘Moderate’, 7-9 is ‘High’, and 10 is ‘Very high’. 14. The UK is also home to numerous low-cost sensors which are operated by a range of private individuals and ...
The index is numbered 1-10 and divided into four bands, low (1) to very high (10), to provide detail about air pollution levels in a simple way. This system was recommended by the Committee on Medical Effects of Air Pollutants (COMEAP). You should follow the 3 step method to use the index. Defra applies the DAQI to its air quality forecasts to ...
An air quality index (AQI) is an indicator developed by government agencies [ 1 ] to communicate to the public how polluted the air currently is or how polluted it is forecast to become. [ 2 ][ 3 ] As air pollution levels rise, so does the AQI, along with the associated public health risk. Children, the elderly and individuals with respiratory ...
