Which of the following is a common source of volatile organic compounds (VOCs) that contribute to tropospheric pollution?
Industrial processes
Agricultural activities
Transportation emissions
All of the above
Volatile organic compounds (VOCs) are a group of organic chemicals that have a high vapor pressure at room temperature. They are found in many different sources and can contribute to tropospheric pollution when they react with nitrogen oxides and other chemicals in the atmosphere. Common sources of VOCs include industrial processes, such as the manufacture of chemicals and plastics; agricultural activities, such as the use of fertilizers and pesticides; and transportation emissions, such as the exhaust from cars, trucks, and airplanes. Other sources of VOCs include consumer products, such as paints, solvents, and cleaning agents..
