Burning of coal and oil, extraction of metals from ore. So2 dissolve in water vapour to form acids. Acids react with other gases and particles and form sulphates. Respiratory illnesses, aggravates existing heart and lung diseases. Variety of organic compounds used as solvent in industry, automobiles. Voc + nox + heat + sunlight = ozone. Summertime pollutant, time of the day, seasonal, climate.
