Once connected, air pollution levels are reported instantaneously and in real-time on our PM2.5 pollution, population exposed to levels exceeding WHO Interim Target-2 value (% of total) PM2.5 pollution, population exposed to levels exceeding WHO Interim Target-3 value (% of total) Nitrous oxide emissions (thousand metric tons of CO2 equivalent) These recommendations may help reduce exposure during short-term pollution episodes in which PM2.5 levels are above 500, since fine particles (PM2.5) are the primary pollutant in wildfire smoke. Who needs to take steps to reduce exposure when PM2.5 levels are “hazardous” or above on the AQI? Since 1997, EPA has evaluated thousands of new studies on PM and, in September 2006, EPA revised the PM standards by lowering the level of the 24-hour PM 2.5 standard to 35 μg/m 3 and retaining the level of the annual PM 2.5 standard at 15 μg/m 3. The Agency retained the 24-hour PM 10 standard of 150 μg/m 3 Particulate matter, or PM2.5, is very small particles in air that are 2.5 micrometers (about 1 ten-thousandth of an inch) or less in diameter. This is less than the thickness of a human hair. Particulate matter, one of six U.S. EPA criteria air pollutants , is a mixture that can include organic chemicals, dust, soot and metals. That, in turn, impacts the planet's ability to generate food and support life.

Meanwhile, the PM2.5 air pollution was behind approximately 160,000 deaths in the world’s 5 most populous cities in 2020, according to a Greenpeace Southeast Asia analysis of IQAir data from a live Cost Estimator. However, the WHO set a guideline limit which reflects the level at which increased mortality from exposure to PM 2.5 is likely. This recommended guideline limit is an annual mean concentration of 10 micrograms per cubic metre of air (µg m-3)3. In the European Union (EU), the legal annual mean air quality limit value (the “legal limit”) for PM 2.5 Average PM2.5 levels in the most polluted capital cities worldwide 2019-2020 Global NOx emissions 1990-2018 Global population exposure to household solid fuel pollution by major country 2017 In this study, pharyngeal swabs from 83 subjects working in an open air farmer's market were sampled before and after exposure to smog with PM2.5 and PM10 levels up to 200 and 300 μg/m 3, respectively.
