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).
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).
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).

SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
Benzo(k)fluoranthene is present as a component of polycyclic aromatic hydrocarbons (PAH) content in the environment usually resulting from the incomplete combustion or pyrolysis of organic matters, especially fossil fuels and tobacco.ACGIH recommends environment containing benzo(k)fluoranthene should be evaluated in terms of the TLV-TWA for coal tar pitch volatile, as benzene soluble 0.2 mg/m3.Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
