Documented Uses

• Not commercially used or produced; [HSDB] 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. [ICSC]
• There is no ... known use of this compound.
• PAHs are generally not produced commercially in the United States except as research chemicals. /Polycyclic aromatic hydrocarbons/
• Substance listed with specific concentration in tattoo ink and/or permanent make up according to EU Commission Regulation 2020/2081. The concentration limit (by weight) is 0.00005%.
• PAHs are released into the environment via the combustion of fossil fuels, coke oven emissions and vehicle exhausts, as well as naturally from forest fires and volcanic eruptions. PAHs from these sources may contaminate nearly water systems. They are also found in coal tar and charbroiled food. (L10)
• There is no commercial production ... of this compound.
