Description and Uses
Acenaphthylene is a PAH with three aromatic rings. It is an intermediate chemical for the manufacture of dyes, soaps, pigments, pharmaceuticals, insecticides, fungicides, herbicides, plant growth hormones, naphthalic acids, naphthalic anhydride (pigments), and acenaphthylene (resins) and is used to manufacture plastics. The largest emissions of PAHs result from incomplete combustion of organic materials during industrial processes and other human activities. These include (1) processing of coal, crude oil, and natural gas, including coking, coal conversion, and petroleum refining; (2) production of carbon blacks, creosote, coal tar, and bitumen; (3) aluminium, iron, and steel production in plants and foundries; (4) heating in power plants and residences and cooking; (5) combustion of refuse; (6) motor vehicle traffic; and (7) environmental tobacco smoke.
