In the article “Air Pollution: Everything You Need to Know”, Jillian Mackenzie mentions 2 types of air pollution that are common and dangerous, smog and soot. Smog is the cause from emission of combusting fossil fuels reacting to sunlight and can get on the eyes and throat and can damage the lungs. Soot is made by tiny particles of smoke, dust, etc. in the form of gas or solids and can penetrate the lungs and bloodstreams, which can cause heart attacks and even death. Air pollution, other than being caused by cars, factories, or power plants, it can also be caused by pollen and mold. The exposure of mold can cause asthma attacks or allergies, and it can also produce toxins that are hard to breathe.
