Air pollutants are substances that have direct impacts on our health and the ecosystem while greenhouse gases damage the planet by warming it, which threatens the survival of all lives on it.
Air pollution affects all things. It is harmful to our health, and it impacts the environment by reducing visibility and blocking sunlight, causing acid rain, and harming forests, wildlife, and agriculture. Greenhouse gas pollution, the cause of climate change, affects the entire planet.
Air pollution, release into the atmosphere of various gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the natural capacity of the environment to dissipate and dilute or absorb them. High concentrations can cause undesirable health, economic, or aesthetic effects.
One of our era's greatest scourges is air pollution, on account not only of its impact on climate change but also its impact on public and individual health due to increasing morbidity and mortality. There are many pollutants that are major factors in disease in humans.
Air pollution is a mix of particles and gases that can reach harmful concentrations both outside and indoors. Its effects can range from higher disease risks to rising temperatures....
Air pollution is one of the world's largest health and environmental problems. It develops in two contexts: indoor (household) air pollution and outdoor air pollution. In this topic page, we look at the aggregate picture of air pollution – both indoor and outdoor.
Outdoor air pollution is a major environmental health problem affecting everyone in low-, middle-, and high-income countries. Ambient (outdoor) air pollution in both cities and rural areas was estimated to cause 4.2 million premature deaths worldwide per year in 2019; this mortality is due to exposure to fine particulate matter, which causes ...
Air pollution kills an estimated seven million people worldwide every year. WHO data shows that 9 out of 10 people breathe air containing high levels of pollutants. WHO is working with countries to monitor air pollution and improve air quality.
There is emerging evidence linking air pollution exposure to cancer, neurodevelopmental and metabolic diseases in children. As well as affecting our health, pollutants in the air are also causing long-term environmental damage by driving climate change, itself a major threat to health and well-being.
The toll of air pollution. Many common pollutants threaten our health when we breathe them in, including ozone, carbon monoxide, nitrogen dioxide and sulfur dioxide. The most dangerous type of air pollution is “particulate matter,” or small solid particles floating in the air.
