I have just finished reading "Bad for Breathing" by Stephen Ornes. The article was about how pollution can cause diseases for the lungs and airways. Inhaling pollution can cause trouble breathing. In can cause asthma. Asthma is a condition that can cause difficulty in breathing, and is sometimes triggered by an allergy. Kids who are exposed to high levels of poly-cyclic aromatic hydrocarbons or PAH are most likely to have have asthma.
When a asthma attack occurs,your small airways in the lungs start to swell, which reduces how much air you can receive. Which means that the person is going to have a very hard time drawing in air to breathe normally.
