What are the origins and environmental implications of pollutants in car exhaust gases

What are the origins and environmental implications of pollutants in car exhaust gases?

By Oscar Miles


Unburned hydrocarbons

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


Carbon monoxide

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


Particulates

Particulates

Origin

  • In complete combustion

    Environmental Effects

  • Health problems including: nausea, difficulty breathing, lung cancer and cardiovascular illnesses.


Carbon dioxide

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


Nitrogen oxides nox

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→ 2NO2NO + O2→2NO2


Sulphur dioxides sox

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
