Pollutants in the air affect human health by entering through the nose and mouth and penetrating blood and lung tissue.
This can lead to diseases such as stroke, diabetes, lung cancer, chronic obstructive pulmonary disease, and heart disease which together account for 90% of the disease burden from air pollution.
8.1 million people died due to air pollution in 2021.
709,000 of them where children under 5.

Air pollution comes from a number of sources
Airborne particulates, including sulfates, nitrates, and particulate matter, can originate from a variety of sources. These include direct sources such as combustion from fossil fuels, car engines, biomass burning, and industrial processes. Indirect sources involve chemical reactions in the atmosphere, such as the formation of secondary pollutants like ground-level ozone and sulfates from the interaction of primary pollutants (e.g., nitrogen oxides, volatile organic compounds) with sunlight and other atmospheric components.
Nearly everyone living in cities is breathing air that doesn't match the WHO's threshold for safe exposure to fine particulate pollution (PM 2.5)
While in some cities air quality has improved
In others it has stagnated
Or worsened all together
While in some cities air quality has improved
In others it has stagnated
And in most it has only gotten worse
Health Impacts
WHERE DOES IT GO?
Humans inhale PM, where fine particles (PM 2.5) can then enter the blood stream and penetrate lung and blood tissue.
HOW BIG IS IT?
Fine particulates (PM2.5) are invisible to the human eye
WHAT IS THE IMPACT?
Fine and ultrafine particles (PM2.5 and smaller) can penetrate deep into the lungs' alveoli sacs and damage the lungs. They can cause nose and throat irritation, respiratory disease, and even lung cancer.
With smog stripes we can compare air quality across different cities
The stripes represents a period of time like a day or year
Each stripe is shaded according to whether air quality on a particular day met or exceeded all levels recommended by the World Health Organization (WHO)
