CAS No. 206-44-0

Formula: C16H10
Basic Info

Fluoranthene is a polycyclic aromatic hydrocarbon (PAH). The molecule can be viewed as the fusion of naphthalene and benzene unit connected by a five-membered ring. Although samples are often pale yellow, the compound is colorless. It is soluble in nonpolar organic solvents. It is a member of the class of PAHs known as non-alternant PAHs because it has rings other than those with six carbon atoms. It is a structural isomer of the alternant PAH pyrene. It is not as thermodynamically stable as pyrene. Its name is derived from its fluorescence under UV light. It is used in the synthesis of Florantyrone.

  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Laboratory studies show that fluoranthene can be substantially mineralized in sediments containing indigenous microorganisms; major metabolites include fluoranthene trans-2,3-dihydrodiol, and 8 and 9-hydroxyfluoranthene trans-2,3-dihydrodiols(1). In shake flask studies, an initial fluoranthene concentration of 16.2 ug/mL was reduced to 7.6 ug/mL following 2 weeks incubation in contaminated groundwater from the American Creosote Works Superfund site, Pensacola, FL(2). In a pilot wastewater treatment plant, no fluoranthene was lost due to biodegradation(3). The presence of the anionic surfactant SDS was found to enhance the biodegradation of fluoranthene(4). Mixed results were reported in a static biodegradability test employing a domestic wastewater inoculum where 100% and 0% of the fluoranthene was degraded in four successive weekly subcultures at concentrations of 5 and 10 mg/L, respectively(5). Fluoranthene removal from the waste water of six municipal waste water treatment plants along the Rhine River in The Netherlands avgd 95%(6).

12.3 Bioaccumulative potential

The BCF of fluoranthene in sunfish was determined to range between 2,640-6,110(1). In a 21 day bioconcentration test in a flow through tank, the log BCF in rainbow trout was 2.58 (BCF = 380)(2). A 28 day experiment in a flow through tank detected a log BCF of 3.60 (BCF = 3,981) after 7 days in fathead minnows; depuration occurred in 2 days(3). According to a classification scheme(4), the BCF values in sunfish, rainbow trout and fathead minnows suggest that the potential for bioconcentration in aquatic organisms is high to very high(SRC). However, it may not bioconcentrate in aquatic organisms which contain microsomal oxidase, such as fish, as this enzyme enables the rapid metabolism of certain polycyclic aromatic hydrocarbons(5). The BCF for fluoranthene in the clam Crassostrea virginica was 10,000 from 8 days exposure to 0.004 ppm fluoranthene via the overlying water column(6). Bioconcentration factors (ratio between tissue and sediment concentrations) of 5.7 and 12.0 were measured in Polychaete sp. and Capitella capitata(7). The BCF of fluoranthene in crayfish was determined to range between 1,520-3,510(1). A mean BCF of 76,696 was measured in the fresh-water amphipod Pontoporeia hoyi(8). When oysters were suspended in oil treated enclosures contaminated with fluoranthene dissolved in Prudhoe crude oil, the log BCF was 4.09 after 2 days exposure; after the oysters were transferred to clean water, depuration half-life was 5 days(9).

12.4 Mobility in soil

The measured log Koc for fluoranthene following 15 days of incubation in Oakland, Mixed and Red Hook sediments was determined to be 4.67 to 5.28, 4.72 to 5.47, and 4.47 to 4.62, respectively(1). The average log Koc value for fluoranthene in sediment from Brown's Lake, MS, and Hamlet City Lake, NC after six months incubation was reported to be 4.51 and 5.05, respectively(2). Sorption coefficients for fluoranthene obtained during 48 hour batch experiments using two lake sediments with an organic carbon content of 1.87 and 2.07%, and a high chemical concentration were 2600 and 2700, respectively(3). The log Koc values for fluoranthene on three soils from Germany and one from China were determined to be 4.81, 4.65, 4.80, and 4.83, respectively(4). The log Kdoc (partition coefficient for sorption to dissolved organic carbon) of fluoranthene was reported to range from 5.12 to 5.22; the log Kpoc (partition coefficient for sorption to particulate organic material was reported to be 5.4(5). Log Koc values reported in the literature were reported to be 4.79(6), 4.62(7), 4.74(8) and 4.87(9). According to a classification scheme(10), these log Koc values suggest that fluoranthene is expected to be immobile in soil(SRC).
