Global air quality index

The World Air Quality Index project has exercised all reasonable skill and care in compiling the contents of this information and under no circumstances will the World Air Quality Index project team or its agents be liable in contract, tort or otherwise for any loss, injury or damage arising directly or indirectly from the supply of this data. Keep track of the most polluted cities in the world with our air quality index (AQI) ranking. Air quality and pollen information for over 1countries in the world. A key tool in this effort is the Air Quality Index , or AQI.

EPA and local officials use the AQI to provide simple information about your local air quality , how unhealthy air may affect you, and how you can protect your health. The AQI is an index for reporting daily air quality. What is the air quality today? Plan your outdoor activities with our health recommendations to reduce your pollution exposure. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you.

EPA sets national air quality standards for six common air pollutants. Each year EPA tracks the levels of these air pollutants in the air. EPA posts the of our analyses to this web site.

Air pollution is a challenge for our entire planet. But from one street to the next, one room the next, the quality of the air you breathe can change significantly. Which is why Plume Labs created Flow, the personal air pollution sensor.

The question is how, and why did we need to come up with this global and unified approach to reporting on air quality ? However, populations in low-income cities are the most impacted. According to the latest air quality database, of cities in low- and middle- income countries with more than 100inhabitants do not meet WHO air quality guidelines. This map provides near real-time information on particulate matter air pollution less than 2. Under typical conditions, PM 2. You can access infographics, databases, maps, and pictures on the WHO website here, or by clicking on the links below. The index ranges from to 50 where high index values indicate higher levels of air pollution and higher potential for adverse health effects. Any value larger than 30 for example, is considered to be hazardous, while an AQI value of 0-5 on the other han represents good air quality.

AirVisual Earth covers pollution airflows across the world by combining PM2. Users can connect their Philips Connected Purifier or Connected Purifier-and-Humidifier Combi to the Air Matters app, to check the indoor air quality index , control the device mode and fan speed from the App and to receive notifications when the air quality is getting worse or when they need to replace the filters. The State of Global Air report brings into one place the most recent information available on levels and trends in air quality and health for countries around the globe.

It develops in two contexts: indoor (household) air pollution and outdoor air pollution. We look in detail at the data and research on the health impacts of Indoor Air Pollution , attributed deaths, and its causes across the world in our full entry: Indoor Air. Where does the data come from? Hello from Pure Earth and the Global Alliance on Health and Pollution ! We are working on a landmark report on the impact of pollution around the globe. Data about the daily mean concentration of air pollutants, especially those potentially harmful to human health.

Data should be available for all air monitoring stations or air monitoring zones in a country. The Index focusses on key pollutants as defined by the World Health Organisation. See our methodology section for more information.

The Air Quality Life Index measures the potential gain in life expectancy that communities could see if they reduced air pollution to comply with the World Health Organization guideline or National standards. Different countries also use different names for their indices such as Air Quality Health Index , Air Pollution Index and Pollutant Standards Index. Check out the most trusted live and forecast air quality information for people and organizations. Helping the world with free AQI data, forecast, API, air quality monitor and solutions for organizations. Air Pollution Data is a combination of Weather Data, Government and Private Air Quality Data, along with Satellite Data.

The data source is Air Visual which compiles data on daily basis. Particle pollution , also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere.
