Statement 1: Photochemical smog is a term used to describe air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere.
Statement 2: One of the primary components of photochemical smog is stratospheric ozone.
Explanation:
Photochemical smog is a type of smog that forms when sunlight reacts with certain pollutants in the atmosphere. It is primarily formed in urban areas with high levels of vehicle emissions and industrial activities. Let's analyze each statement:
Statement 1: Photochemical smog is a term used to describe air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere.
This statement is correct. Photochemical smog is formed when sunlight reacts with certain pollutants, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs), in the presence of oxygen and other atmospheric components. The reaction produces a complex mixture of secondary pollutants, including ozone, aldehydes, and other harmful compounds.
Statement 2: One of the primary components of photochemical smog is stratospheric ozone.
This statement is incorrect. While ozone is indeed a component of photochemical smog, it is not derived from the stratospheric ozone layer. Stratospheric ozone is a vital layer in the Earth's atmosphere that protects us from harmful ultraviolet (UV) radiation. On the other hand, the ozone present in photochemical smog is formed as a secondary pollutant through a series of chemical reactions involving sunlight and pollutants like NOx and VOCs.
Therefore, only Statement 1 is correct. Photochemical smog is indeed a result of the interaction of sunlight with certain chemicals in the atmosphere, while stratospheric ozone is not a primary component of photochemical smog.
Statement 2: One of the primary components of photochemical smog is stratospheric ozone.
