👉 Proxy fumes refer to the indirect pollutants released into the air by industrial processes or vehicles, which then react with other atmospheric components to form secondary pollutants like ozone and particulate matter. These fumes are not directly emitted but are created when primary pollutants, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs), interact with sunlight and other chemicals in the atmosphere. This chemical transformation can lead to the formation of harmful air quality issues, affecting both human health and the environment. Understanding proxy fumes is crucial for developing effective strategies to mitigate air pollution.
