  1. What are the origins and environmental implications of pollutants in car exhaust gases? By Oscar Miles

  2. Unburned Hydrocarbons Origin • Product from in complete combustion and evaporation Environmental Effects • Cancer • Asthma • Smog Chemical Equations: • CxHy + (x + y/4) O2 xCO2 + (y/2) H2O • CxHy + (2x + y/4) O2 xCO + (y/2) H2O

  3. Carbon Monoxide • Origin: From incomplete combustion. Environmental Effects • Contributes to photochemical smog, • Irritation, and high exposure can lead to death. Chemical Equation: O2 + 2 C → 2 CO

  4. Particulates Origin • In complete combustion Environmental Effects • Health problems including: nausea, difficulty breathing, lung cancer and cardiovascular illnesses.

  5. Carbon dioxide Origins: Combustion Environmental Effects • Can be damaging to health in high concentrations • Large contributor global warming Chemical Equation: 2O2 + 2 C → 2 C2O

  6. Nitrogen Oxides (NOx) Origin: combustion of nitrogen in air. Environmental Effects • Toxic to humans - Causes acid rain • Contributes to photochemical smog • Damages ozone layer Chemical equations: N2 + O2→ 2NO 2NO + O2→2NO2

  7. Sulphur Dioxides (SOx) Origin - Forms when sulphur combusts in air Environmental effects: • Damaging to humans, plant and animal life • Acid rain. • Chemical Equations: S + O2→SO2 2SO2 + O2→2SO3
