The types of pollution that include CFCs (chlorofluorocarbons) and smog are air pollution and specifically, they are related to ozone depletion and urban air pollution respectively.
CFCs are a type of chemical compound that were commonly used in refrigerants, air conditioning systems, and aerosol sprays. When released into the atmosphere, CFCs can react with ozone molecules in the upper atmosphere and cause ozone depletion, which can result in harmful levels of ultraviolet radiation reaching the Earth’s surface. This type of pollution is commonly referred to as ozone depletion.
On the other hand, smog is a type of air pollution that occurs when emissions from vehicles, factories, and other sources react with sunlight to create a mixture of pollutants, including ground-level ozone, particulate matter, and other compounds. Smog is commonly found in urban areas with high levels of traffic and industrial activity and can have a range of negative impacts on human health and the environment.
