Answer
We differ primary pollutants like nitrogen oxide, volatile organic compounds, and sulfur dioxide, which is made by motor vehicles and some industrial processes (power plants) and released in the atmosphere. Secondary pollutants are made from the primary pollutants in the presence of UV light ($NO_{2}, O_{3}$).
