Polycyclic Aromatic Hydrocarbons (PAHs)
Polycyclic aromatic hydrocarbons (PAHs)—sometimes referred to as polynuclear aromatic hydrocarbons (PNAs), condensed ring aromatics, or fused ring aromatics—are a class of organic compounds consisting of two or more fused aromatic rings ( Figures 15.1.1 and 15.1.2). Naphthalene, consisting of two fused benzene rings, is the simplest PAH.
