How does pollution affect the airways?
LUNGS. When you breathe in, air moves through your nose or mouth, down your throat into your trachea, and then into your lungs. Pollution can irritate the airways. When that happens, muscles around the bronchi get tight; the lining of the bronchi swell; and the bronchi produce excess mucous.
What happens when you have asthma?
That’s what happens during an asthma attack. Air pollution makes infections worse and makes the lungs more susceptible to getting infections in the first place. Pollution causes your airways to narrow, decreasing airflow, and amps up the production of mucous.
Why are children more vulnerable to air pollution than adults?
Children are especially vulnerable to air pollution. Children breathe faster than adults, so they are exposed to more air pollution than adults. They exercise more and spend more time outside than adults, which means that they breathe more outdoor air pollution. Children’s lungs are still developing, and developing lungs are more sensitive to pollution than fully formed lungs.

How much air pollution is safe?
So how polluted can air be before it starts to affect our health? For PM2.5, WHO guidelines say the maximum safe level is an annual average concentration of 10 μg/m 3 or less. To encourage cities to reduce air pollution, even if they are unable to meet the ideal safe levels, WHO has set three interim targets for cities. These are: 15 μg/m 3 (interim target 3); 25 μg/m 3 (interim target 2); 35 μg/m 3 (interim target 1). Many cities are now exceeding the very upper level of interim target 1.

Releasing chlorine atoms into the atmosphere destroys ozone. A single chlorine atom can destroy thousands of ozone molecules. The ozone layer blocks harmful UVB radiation from the Sun- it protects us in a way that is similar to putting sunscreen on your skin to prevent sunburn.
How does ozone affect plants?
Ozone pollution harms plants by damaging structures called stomata, which are tiny pores on the underside of leaves that allow the plant to "breathe.". Some types of plants can protect themselves by temporarily closing their stomata or producing antioxidants, but others are particularly sensitive to damage.

People can experience exposure to varying concentrations of air pollution. Poor air quality can impact individuals for a short period of time during the day, or more frequently during a given day. Exposure to pollutants can also occur over multiple days, weeks or months due to seasonal air pollution, such as increased ozone during the summer or particulate matter from woodstoves during the winter.
What are the effects of air pollution?
Decades of research have shown that air pollutants such as ozone and particulate matter (PM) increase the amount and seriousness of lung and heart disease and other health problems.
