What is the Source of Air Pollution?
Air pollution forms when nitrogen oxides (NOx) from emission sources combine with sunlight and intense heat to create ground-level ozone, commonly known as smog. On-road and off-road mobile sources, such as cars, trucks, construction vehicles and air planes, cause over 70% of North Texas air pollution. Use of chemicals, paints and pesticides along with emissions from power plants and factories create 25% of North Texas air pollution. Panel 2: Why Does Pollution Persist in the Atmosphere? The ozone layer traps NOx emissions in our atmosphere. these emissions cannot escape, so pollution increases. The protective ozone layer forms high in the stratosphere. This layer forms naturally and protects us from the sun’s radiation. Air pollution forms in Earth’s troposphere, near the ground. Harmful ground-level ozone forms when emissions from vehicles, power plants, factories and chemicals react with nitrogen and oxygen. Panel 3: How Can I Improve Air Quality?
