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

By Oscar Miles


Unburned hydrocarbons l.jpg
Unburned Hydrocarbons pollutants in car exhaust

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 l.jpg
Carbon Monoxide pollutants in car exhaust

  • 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 pollutants in car exhaust

Origin

  • In complete combustion

    Environmental Effects

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


Carbon dioxide l.jpg
Carbon dioxide pollutants in car exhaust

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 l.jpg
Nitrogen Oxides ( pollutants in car exhaust 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


Sulphur dioxides sox l.jpg
Sulphur Dioxides ( pollutants in car exhaust 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
