Pyrene
Identifier: 31423
URL: https://pubchem.ncbi.nlm.nih.gov/compound/31423#section=2D-Structure
Polycyclic aromatic hydrocarbon with four connected six-membered rings
Pyrene occurs in fossil fuels and coal tar and is a ubiquitous product of incomplete combustion. It is found e.g. in tobacco smoke, emissions from wood-, oil- and coal-burning ovens, exhausts from engines, and smoked foods.
Furthermore, it is used as starting material in the production of dyes and optical brighteners.
In the atmosphere, it is found in the gaseous phase as well as in the particle-phase. Gaseous pyrene is degraded photochemically, whereas particle-bound pyrene may enter soils and surface waters through wet and dry deposition.
Pyrene is relatively persistent in the environment and is accumulated by organisms.
It is toxic. Due to lack of data, carcinogenicity and other health effects can not be evaluated.
Pyrene is one of 16 PAHs which were included in the EPA-list of Priority Pollutants.
