ACUTE/CHRONIC HAZARDS: When heated to decomposition, this compound emits acrid smoke and irritating fumes.

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).

Flash point data for this chemical are not available; however, BENZO[B]FLUORANTHENE is probably combustible.

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Benz[e]acephenanthrylene is a polycyclic aromatic hydrocarbon that was detected in significant levels in airborne polluants, auto exhaust and tobacco and marijuana smoke.

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.

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).

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).
