The map provides hourly readings, and by hovering over flags representing different cities, users can access historical air pollution data for specific locations.
Another resource is IQAir, which provides a World Live Air Quality Map. This map includes data on PM2.5 and PM10 particulate matter, as well as ozone (O3), a naturally occurring compound that blocks harmful UV rays in the atmosphere but is toxic at ground level. The map also highlights the impact of natural sources of air pollution, such as volcanic activity, wildfires, and dust or sandstorms, and household pollution from cooking, heating, and construction.
AirNow.gov is another website that provides an interactive real-time air pollution map, particularly useful for checking the impact of wildfire smoke on air quality. It offers AQI calculators and health activity guides, especially for individuals with asthma and heart disease. Additionally, AirNow provides a mobile app, email alerts, and web cameras for users seeking more tailored information on air quality in their specific locations.
These real-time air pollution maps are made possible through data collected by worldwide Environmental Protection Agencies (EPA) and individual air quality stations. While the data provided is carefully compiled, it is subject to change without notice for quality assurance purposes.

Air Quality Index (AQI)
The Air Quality Index (AQI) is a tool used to communicate information about outdoor air quality and health. The AQI is measured on a scale from 0 to 500, with higher values indicating greater levels of air pollution and health concerns. For instance, an AQI value of 50 or below represents good air quality, while an AQI value over 300 indicates hazardous air quality. The AQI is divided into six colour-coded categories, each representing a different level of health concern. This colour-coding system allows individuals to quickly assess the air quality in their communities.
The AQI is calculated based on the measurement of several pollutants, including particulate matter (PM2.5 and PM10), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO) emissions. These measurements are taken using laser particle sensors, such as the GAIA air quality monitor, which provide real-time data by connecting to a WiFi access point and a USB power supply.
Websites like AirNow.gov provide interactive maps that display the AQI for various locations, including local, state, national, and world views. These maps allow users to check the current AQI and determine whether air quality is satisfactory or unhealthy. The AQI data is based on the latest US EPA standards and is continuously updated to ensure accuracy.
It is important to note that AQI values above 100 indicate unhealthy air quality for certain sensitive groups, and as the values increase, the air quality becomes unhealthy for everyone. Therefore, it is essential to stay informed about the AQI in your area and take necessary precautions to protect your health when the AQI reaches unhealthy levels.

Air pollution and health
Air pollution is a critical public health issue that contributes to millions of deaths annually and is the second leading risk factor for death worldwide. According to the World Health Organization (WHO), 99% of the global population breathes air that exceeds their air quality guidelines.
The health impact of air pollution exposure depends on the duration and concentration of exposure, as well as the health status of the affected populations. Research has shown that air pollutants, such as ozone, fine particle pollution (PM2.5 and PM10), and nitrogen dioxide (NO2), can have detrimental effects on human health. These pollutants are primarily produced by vehicle emissions, coal-burning power plants, and industrial emissions. Due to their microscopic size, PM2.5 particles can penetrate deep into the lungs and even enter the bloodstream, causing or aggravating various health issues. Nitrogen dioxide is linked to asthma development in children and the exacerbation of symptoms in asthmatics.
Children, the elderly, pregnant women, and individuals with pre-existing heart and lung conditions are especially susceptible to the adverse effects of air pollution. Additionally, people living in areas with high pollution levels, low socioeconomic neighborhoods, and those with underlying health issues, poor nutrition, or stress may be more vulnerable to its impacts.
To address these concerns, organizations like Vital Strategies provide technical expertise and collaborate with governments worldwide to improve air quality monitoring, identify leading sources of pollution, and develop effective policies. Local interventions have shown success, with cities like Beijing and London significantly reducing PM2.5 and NO2 levels through emission controls and fuel quality standards.
Air quality monitoring tools, such as the Air Quality Index (AQI), help assess the level of air pollution and the associated health concerns. The AQI is based on the measurement of particulate matter, ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide emissions, with higher values indicating greater pollution and health risks.
