Возможный контакт

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).

Канцерогенность

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.

Экологическая судьба

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).

Несовместимости

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.

Утилизация отходов

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.
