Documented Uses

• Used for scientific research; Not commercially used or produced; [HSDB] Benzo(ghi)perylene 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]
• Small amounts are used for scientific research.
• 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/
• 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 vocanic 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.
