Total Hydrocarbons (THC)

THC is a group of compounds that are mostly colourless, flammable, non-toxic gases with very characteristic odours associated to the various compounds. Examples include: methane, ethane, propane and butane.

How Is It Generated?

THC is a broad term used to describe compounds which are essentially contain Hydrogen and Carbon atoms. They often occur in petroleum, natural gas and coal. They are generated through the use of these fuels, and specifically the combustion and storage of these compounds. Anthropogenic sources: vehicular emissions, fuel storage tanks, petroleum and chemical industries, dry cleaning, fireplaces, natural gas combustion, aircrafts. Natural Sources: vegetation decomposition.

What Are The Health Effects?

Provincial Guidelines:

What Can Be Done?

  1. Conserve energy.
  2. Use alternative fuel sources. Sources like wind, solar, and hydro power all result in reductions to the generation of THC.
