it would be super helpful if someone could tell me ways that each of these things are produced!!!
NOx is formed when atmospheric nitrogen and oxygen react as a result of exposure to high temperatures; occurs in combustion engines. Other sources are utilities and industrial combustion.
SOx is a powerful respiratory irritant that is released through the combustion of coal
sources: metal smelting, paper pulping, and the burning of fossil fuels.
VOCs can be found in household products with strong smells, like paints, cleaners, and car fresheners. NOx and SOx can both be found from car emissions.
