Description

Benzo[k]fluoranthene is an organic compound with the chemical formula C20H12. Classified as a polycyclic aromatic hydrocarbon (PAH), it is a colourless solid that is poorly soluble in most solvents. Impure samples can appear off white. Closely related isomeric compounds include benzo(a)fluoranthene, benzo(b)fluoranthene, benzo(e)fluoranthene, and benzo(j)fluoranthene.
More than 20% of the carbon in the universe may be associated with PAHs, including the benzofluoranthenes.

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: In a static biodegradability test employing a domestic wastewater inoculum, 50-70% of benzo(k)fluoranthene was degraded in four successive weekly subcultures(1). After 60 days of batch slurry bioremediation, the initial solid-phase benzo(b,k)fluoranthene concentration of 120 ug/g was reduced to 50.4 ug/g, a 58% removal(2). In shake flask studies, an initial benzo(b,k)fluoranthene concentration of 2.9 ug/mL was reduced to 1.7 ug/mL following 2 weeks incubation in contaminated groundwater from the American Creosote Works Superfund site, Pensacola, FL; the concentration in a sterile control was 2.8 ug/mL(3). In bench-scale biotreatability studies using a solid-phase bioremediation process (landfarming chambers containing sediment and soil collected from the American Creosote Works Superfund site, Pensacola, FL), the benzo(b,k)fluoranthene concentration was reduced from 112.8 to 109.8 mg/landfarming chamber in unamended surface soil; 112.8 to 81.3 mg/landfarming chamber in nutrient-amended surface soil; 418.8 to 345.6 mg/landfarming chamber in unamended sediment; and 418.7 to 351.6 mg/landfarming chamber in nutrient-amended sediment following 12 weeks incubation(4).

12.3 Bioaccumulative potential

An estimated BCF range of 3415-6465 was calculated in fish for benzo(k)fluoranthene(SRC), using a log Kow range of 5.86-6.28(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF range suggests that the potential of benzo(k)fluoranthene for bioconcentration in aquatic organisms is very high(SRC). Polyaromatic hydrocarbons, including benzo(k)fluoranthene, have been shown to be rapidly metabolized by some aquatic organisms(4). BCFs for benzo(k)fluoranthene, based on dry weight, in mussels (Mytilus edulis planulatus L.) incubated in Port Phillip Bay, Australia were 37,000-60,000 in water with no direct source of hydrocarbons; 27,000-30,000 in areas where the main sources of hydrocarbons is urban drainage, and 200,000-310,000 in sites close to the discharge of a major oil refinery(5). The biota-sediment accumulation factor (BSAF) for benzo(k)fluoranthene determined using oligochaete worm (Lumbriculus variegatus) was 0.63 and 0.21 in Lake Erie sediment from Vermilion, OH and Dunkirk, NY, respectively(6).

12.4 Mobility in soil

The log Koc value for benzo(k)fluoranthene in 100 soil samples was 6.81-7.91(1). According to a classification scheme(2), these measured Koc values suggest that benzo(k)fluoranthene is expected to be immobile in soil. The log Koc values of benzo(k)fluoranthene measured in sediment from San Francisco Bay was 6.01-6.70(3). Sorption coefficients for benzo(k)fluoranthene measured using two lake sediments with organic carbon content of 1.87 and 2.07%, and a high chemical concentration were 6100 and 20,000, respectively(4). Sorption coefficients measured using a low benzo(k)fluoranthene concentration were 7300 and 26,000 using the same respective sediments(4). These values correspond to Koc values of 3.3X10+5, 9.7X10+5, 3.9X10+5 and 1.3X10+6(5). The log Koc value of benzo(k)fluoranthene measured in sediment from Lake Ketelmeer was 6.74 and 6.89(6). The log Koc values for benzo(b,k)fluoranthene in 52 sediment samples was 5.61-8.44(7).
