The UNICEF, says: The new SoGA Report offers a detailed analysis of recently released data from the Global Burden of Disease study from 2021 that shows the severe health impacts pollutants like outdoor fine particulate matter (PM2.5), household air pollution, ozone (O3), and nitrogen dioxide (NO2) are having on human health around the world. The report includes data for more than 200 countries and territories around the world, indicating that nearly every person on earth breathes unhealthy levels of air pollution every day, with far-reaching health implications.
PM2.5 refers to particles in the atmosphere with an aerodynamic diameter of less than 2.5 micrometres. These particles, which are very small in diameter, can penetrate into the alveoli in the lungs. From the alveoli, they can mix with the blood and reach the lungs, heart, brain, liver and kidneys and damage the organs. These particles may contain heavy metals, black carbon, VOCs and PAHs, which are extremely harmful to human health.
