15 Fluoranthene
� Fluoranthene is a PAH. It is persistent and
may have genotoxic properties.
� Fluoranthene is mostly monitored as part of
�PAH in Norway.
� For further information, see PAH.
Production and use
Fluoranthene occurs primarily in products of
incomplete combustion such as cigarette smoke
and engine exhaust. Fluoranthene has also been
identified in food products such as charbroiled
hamburger and seafood, as well as in butter,
fats, and oil. Fluoranthene has been found in
emissions from oil fires, municipal waste incinerators
etc. It also occurs in crude oil and fossil
fuels. Fluoranthene is also a content of bitumen
road tar-and roof sealant). Globally, commercially
produced fluoranthene is used in the production
of fluorescent and vat dyes (CIRCA,
HSDB).
Emissions, discharges,
distribution and hot-spots

Monitoring
Fluoranthene is monitored with �PAH in
Norway.

FACTS
Cas no.: 206-44-0
fluoranthene ::::::::::..
Synonyms: 1,2-benzacenaphthene, benzene, 1,2-(1,8naphthalenediyl)-benzene,
1,2-(1,8-naphthylene),
benzo(jk)fluorene, 1,2-(1,8-naphthylene)benzene
Properties: Pale yellow crystals or needles
Toxic effects: Fluoranthene is an irritant. LC50 for
Mysid shrimp is 40 µg/l/96 h, while LC50 for Bluegill
(Leponis macrochirus) is 3 980 µg/l/96 h.
Fluoranthene is not classified as a human carcinogen,
but it may have genotoxic properties.
Log Kow: 4,7
Persistence: Half-life for fluoranthene is up to 7,8
years (biodegradation) in soil. Half-life in water
(direct photochemical decomposition of fluoranthene
in fresh water) is calculated to 21,0 hours near
the surface. Half-life in sediment is 143 - 182 days
(biodegradation), while half-life in air is 8 hours (photodegradation,
vapour) according to HSDB.
Bioconcentration in aquatic organisms is high to very
high.
Water solubility: 0,265 mg/l at 20 °C
Molecular formula: C1 6 H 10
Metabolites: Fluoranthene trans-2,3-dihydrodiol, and
8 and 9-hydroxyfluoranthene trans-2,3-dihydrodiols
(bacteria).
