Documented Uses

• Used in insecticides and fungicides and in the manufacture of dyes and plastics; [CAMEO] Present in crude oil and coal tar; Produced during combustion (including natural fires), petroleum refining, and coal tar distillation; Has been detected in the atmosphere of a lumber creosote impregnation plant, at the coal preparation area of a solvent refined coal pilot plant, in an aluminum plant, and in smokehouses; [HSDB] Used as an intermediate for resins; [INCHEM EHC]
• Aluminum Producing [Category: Industry]
• Petroleum Production and Refining [Category: Industry]
• Applying Wood Preservatives [Category: Other]
• Acenaphthylene has been used to investigate the photodimerization of acenaphthylene in micellar and hydrogel media.
• 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)
