mögliche Exposition
There is no commercial production of this compound. Benzo(b)fluoranthene is a chemical substance formed during the incomplete burning of fossil fuel, garbage, in cigarette smoke, or any organic matter and is Benzofluoranthene 399 found in smoke in general; it is carried into the air, where it condenses onto dust particles and is distributed into water and soil and on crops. B(b)F is a PAH and a component of coal tar pitch used in industry as a binder for electrodes. It is also a component of creosote, which is used to preserve wood. PAHs are also found in limited a mounts in bituminous materials and asphalt used for paving, roofing, and insulation. B(b)F has some use as a research chemical. It is available from some specialty chemical firms in low quantities (25 100 mg).
Erste Hilfe
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, rinsemouth and get medical attention.
Carcinogenicity
Benzo[b]fluoranthenewas tested for carcinogenicity by dermal application in mice in multiple studies, intraperitoneal injection into mice in multiple studies, and intrapulmonary implantation into rats in one study. In all of these studies, benzo[b]-fluoranthene exhibited a significant carcinogenic activity.
Source
Benzo[b]fluoranthene and benzo[k]fluoranthene were detected in 8 diesel fuels at concentrations ranging from 0.0027 to 3.1 mg/L with a mean value of 0.266 mg/L (Westerholm and Li, 1994). Also present in low octane gasoline (0.16–0.49 mg/kg), high octane gasoline (0.26– 1.34 mg/kg), used motor oil (2.8–141.0 mg/kg), and bitumen (40 to 1,600 ppb), cigarette smoke (3 g/1,000 cigarettes), and gasoline exhaust (19 to 48 g/L) (quoted, Verschueren, 1983). Also detected in asphalt fumes at an average concentration of 22.04 ng/m³ (Wang et al., 2001). Nine commercially available creosote samples contained benzo[b]fluoranthene at concentrations ranging from 2 to 96 mg/kg (Kohler et al., 2000).
Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The particle-phase emission rates of benzo[b]fluoranthene were 0.790 mg/kg of pine burned, 0.400 mg/kg of oak burned, and 0.327 mg/kg of eucalyptus burned.
Particle-phase tailpipe emission rate from a noncatalyst-equipped gasoline-powered automobile was 37.3 μg/km (Schauer et al., 2002).
Environmental Fate
Biological. Ye et al. (1996) investigated the ability of Sphingomonas paucimobilis strain U.S. EPA 505 (a soil bacterium capable of using fluoranthene as a sole source of carbon and energy) to degrade 4, 5, and 6-ringed aromatic hydrocarbons (10 ppm). After 16 h of incubation using a resting cell suspension, only 12.5% of benzo[b]fluoranthene had degraded. It was suggested that degradation occurred via ring cleavage resulting in the formation of polar metabolites and carbon dioxide.
Soil. The reported half-lives for benzo[b]fluoranthene in a Kidman sandy loam and McLaurin sandy loam are 294 and 211 d, respectively (Park et al., 1990).
Photolytic. The atmospheric half-life was estimated to range from 1.43 to 14.3 h (Atkinson, 1987).
Chemical/Physical. Benzo[b]fluoranthene will not hydrolyze because it has no hydrolyzable functional group (Kollig, 1993).
Lager
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Store in a cool, dry place. Aregulated, marked area should be established where thischemical is handled, used, or stored in compliance withOSHA Standard 1910.1045.

Inkompatibilitäten
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
Waste disposal
Residues and sorbent media may be packaged in 17H epoxy-lined drums and disposed of at an EPA-approved site. Destroy by permanganate oxidation, high-temperature incineration with scrubbing equipment, or microwave plasma treatment, if available. Confirm disposal procedures with responsible environmental engineer and regulatory officials.
