Danielle Gibbins Photochemical smog contains Ozone (O3), a powerful oxidising agent. Ozone is formed when sunlight shines on primary pollutants. A primary pollutant is a pollutant released directly into the atmosphere. For example the primary pollutant NOx is emitted from vehicle exhausts and contains 95% NO and small amounts of NO2. 1 Ozone is what we call a secondary pollutant because it is formed when primary pollutants undergo further reactions. Other constituents of photochemical smog are given below. Living organisms contain sulphur compounds and because coal is formed from the gradual compacting of partially decomposed plant matter 3, coal also contains sulphur compounds. When the coal is burnt the sulphur compounds are converted to oxides of sulphur, which are primary pollutants. Also proteins in the organisms contained Nitrogen compounds and when the coal is burnt these are oxidised to form NOx, and at high temperatures used for combustion Nitrogen and Oxygen in the air combine to...
