An organic substance is a substance that contains carbon. Organic substances are found in all living things, and they are also found in many non-living things, such as petroleum and coal.

Asbestos is not an organic substance. It is a mineral that is found in the earth’s crust. Asbestos is not made up of carbon atoms, and it does not contain any other organic elements.
