Real-time monitoring data from continuous monitors are typically available as 1-hour averages. However, computation of the AQI for some pollutants requires averaging over multiple hours of data. (For example, calculation of the ozone AQI requires computation of an 8-hour average and computation of the PM 2.5 or PM 10 AQI requires a 24-hour ...
Worldwide, PM 10 concentrations of 70 μg/m 3 and PM 2.5 concentrations of 35 μg/m 3 have been shown to increase long-term mortality by 15%. [29] More so, approximately 4.2 million of all premature deaths observed in 2016 occurred due to airborne particulate pollution, 91% of which occurred in countries with low to middle socioeconomic status.
The guidelines stipulate that PM 2.5 should not exceed 5 μg/m 3 annual mean, or 15 μg/m 3 24-hour mean; and that PM 10 should not exceed 15 μg/m 3 annual mean, or 45 μg/m 3 24-hour mean. [2] For ozone (O 3), the guidelines suggest values no higher than 100 μg/m 3 for an 8-hour mean and 60 μg/m 3 peak season mean. [2]

A 2023 study on sulfur dioxide emissions by coal power plants (coal PM 2.5) concluded that "exposure to coal PM 2.5 was associated with 2.1 times greater mortality risk than exposure to PM 2.5 from all sources." [133] From 1999 to 2020, a total of 460,000 deaths in the US were attributed to coal PM 2.5. [133]

[218] Inhalation of PM 2.5 – PM 10 is associated with elevated risk of adverse pregnancy outcomes, such as low birth weight. [219] Exposure to PM 2.5 has been associated with greater reductions in birth weight than exposure to PM 10. [220]
