Which of the following is not a primary pollutant in the formation of smog?
Nitrogen Oxides
Volatile Organic Compounds
Sulfur Dioxide
Carbon Dioxide
Smog is a type of air pollution that is formed when primary pollutants, such as nitrogen oxides and volatile organic compounds
, react in the presence of sunlight and heat. The reaction leads to the formation of secondary pollutants, such as ground-level ozone
and fine particulate matter
, which are harmful to human health and the environment.
Nitrogen oxides are emitted by vehicles, power plants, and industrial processes, and are a major contributor to the formation of smog.
reacts with VOCs in the presence of sunlight and heat to form ground-level ozone
, which is a key component of smog.
Volatile organic compounds (VOCs) are emitted by a variety of sources, including gasoline-powered vehicles, solvents, and consumer products. VOCs also react with in the presence of sunlight and heat to form ground-level ozone
Sulfur dioxide is another primary pollutant that contributes to the formation of smog.
is emitted by power plants and industrial processes that burn fossil fuels, and it can react with other pollutants in the atmosphere to form secondary pollutants such as sulfuric acid and particulate matter.
Carbon dioxide is not considered a primary pollutant in the formation of smog. While
is a greenhouse gas that contributes to climate change, it does not directly contribute to the formation of smog.
is primarily emitted by the combustion of fossil fuels, and efforts to reduce
emissions are focused on addressing climate change rather than air pollution.
