Where did it come from?
People assume that oil coming from oil pollution is the result from a damaged oil tanker. What people don't realize is that there is more than just one source of oil pollution. Oil comes from a mixture of many different chemicals and it depends on where the chemicals derived from. i.e., the conditions/place. Biomarkers are known as an organic chemicals that may be combined and used to create an imprint of an oil sample. They hen compare this print with many different oil samples.
