Pollutants can also make kids more likely to catch upper respiratory infections (like colds), which can bring on asthma symptoms.
Can vehicle emissions cause asthma?
Four million children develop asthma every year as a result of air pollution from cars and trucks, equivalent to 11,000 new cases a day, a landmark study has found.
How does pollution affect children’s development?
Exposures to even low levels of pollution during the first 1000 days can stunt children’s growth, increase their risk of disease, and cause lasting damage to their brains, lungs, reproductive organs and immune systems (Landrigan and Etzel, 2013).
What type of pollution causes asthma?
Airborne particles Other forms of air pollution may also trigger your asthma. Small particles in the air can pass through your nose or mouth and get into your lungs. Airborne particles, found in haze, smoke and airborne dust, present serious air quality problems.
What pollutants affect asthma?
Two key air pollutants can affect asthma. One is ozone (found in smog). The other is particle pollution (found in haze, smoke, and dust). When ozone and particle pollution are in the air, adults and children with asthma are more likely to have symptoms.
Does pollution worsen asthma?
Researchers have long linked asthma— a serious and life threatening chronic respiratory disease that affects the quality of life of more than 23 million Americans— with exposure to air pollution. Air pollution can make asthma symptoms worse and trigger asthma attacks.
How does air pollution affect the lungs kids?
Air pollution affects your child’s lungs both before and after birth. Exposure to air pollution can harm normal growth of lung function in the womb, during childhood and right up to the late teens. In children with asthma, high levels of air pollution are linked to increased asthma attacks.
Can petrol fumes cause asthma?

How does air pollution affect the lungs for kids?
Exposure to air pollution can harm normal growth of lung function in the womb, during childhood and right up to the late teens. In children with asthma, high levels of air pollution are linked to increased asthma attacks.
Why are children more at risk for indoor air pollution?
Children face special risks from air pollution because their lungs are growing and because they are so active and breathe in a great deal of air.
