Air pollution is scientifically correlated to a range of health conditions, and causal links between air pollution exposure and deadly diseases including stroke, chronic kidney disease, heart disease, lung diseases, and other conditions. Overall, the impact of air pollution on our health results in reduced life expectancy.
In this article, air quality experts from global air filtration leader Camfil discuss the 2022 AQLI report findings.
What Is the Air Quality Life Index?
The Air Quality Life Index, or AQLI, is a metric produced by the Energy Policy Institute at the University of Chicago (EPIC) that expresses air pollution concentration in terms of its impact on human life expectancy. In addition to showing the impacts of current pollution levels, the AQLI makes policy suggestions to reduce air pollution exposure and increase our life expectancy.
While many efforts to reduce air pollution focus on CO2 and other greenhouse gases, particulate matter is considered by the EPA to be the greatest environmental threat, as well as the deadliest to the human body.
Particulate matter pollution has declined by 64.2% in the United States since the introduction of the Clean Air Act in 1970, leading to an increased life expectancy of 1.3 years. Despite this success, recent scientific evidence has shown that 92.8% of the U.S. population are living in areas with unsafe levels of pollution according to guidelines by the World Health Organization.
AQLI Findings in the United States
Despite overall reductions in pollution levels since 1998, there is still room for improvement:
- The average level of particle pollution in the United States was 7.1 μg/m3 as of 2020. This is above the World Health Organization’s guideline of 5 μg/m3.
- If pollution levels were to be reduced to the WHO guideline, the average American could expect to gain 2.5 months of life expectancy, which totals 68 million life years for the whole population.
- The West Coast, particularly California’s Central Valley, would see the greatest benefit from reductions in pollution, where increasingly severe wildfires in recent years have led to rising pollution levels.
- In 2020, 19 of the 20 most polluted counties in the United States were in California.
- In the nation’s most polluted county, Mariposa County’s pollution levels stand at 22.6 μg/m3. Residents stand to gain 1.7 years of life expectancy if air pollution isreduced to the WHO guideline.
AQLI Findings Across the World — Air Pollution Impact on Global Life Expectancy
In other countries around the world, air pollution has a much greater impact on average life expectancy. Here are some of the most severely impacted countries:
- Bangladesh — 6.9 years
- China — 2.6 years
- India — 5.0 years
- Indonesia — 5.0 years
- Pakistan — 3.8 years
Air Filtration Technology Reduces Air Pollution Exposure
Policy changes are a slow process, and the practical effects of those changes can be even slower. What can we do to protect our bodies from the effects of particle air pollution in the meantime?
Given that Americans spend an average of 90% of their time indoors, where particulate matter concentration is often two to five times higher than outside, ensuring that indoor air stays clean is essential for keeping Americans safe. Fortunately, a range of science-backed air filtration solutions are available to meet the varying needs of different applications.
