Chemical stability of aromatic hydrocarbons and their high toxicity cause an increased risk for these substances gets into the environment. In nature, there are micro-organisms that can destroy the aromatic nucleus to the compounds that are joining in the natural cycle, eventually turning into CO2 and H2O. However, the microbiological degradation are rings containing at least two hydroxyl substituents in the ortho or para position. If aromatic hydrocarbons are resistant to oxidation, the risk of them when released into the environment increases dramatically due to their ability to accumulate in living organisms...
