Fluoranthene is a polycyclic aromatic hydrocarbon. The molecule can be viewed as the fusion of naphthalene and benzene unit connected by a five-membered ring. The chemical formula is C16H10. Although

…coal tar, where it occurs up to 2% by weight. As a peri-fused PAH, pyrene is much more resonance-stabilized than its five-member-ring containing isomer fluoranthene. Therefore, it is produced in a wide range of combustion conditions. For example, automobiles produce about 1 μg/km. Pyrene contains two kinds of ring…
