Aromatic hydrocarbons contain one or more carbon rings. They are typified by benzene, which contains six carbon atoms and three double bonds. Derived chiefly from petroleum and coal tar, aromatic hydrocarbons tend to be reactive. The designation...

An aromatic hydrocarbon (abbreviated as AH) or arene [1] is a hydrocarbon, the molecular structure of which incorporates one or more planar sets of six carbon atoms that are connected by delocalised electrons numbering the same as if they consisted of...

Polyclinic aromatic hydrocarbons (PAHs, or polynuclear aromatic hydrocarbons) are widespread in the environment. They are characterized by the presence of three or more fused five- or six-membered aromatic rings (see Figure 1), relatively high-molecular weights, and hydrophobicity. Their nomenclature is complex, and the...

ABSTRACT The presence of polycyclic aromatic hydrocarbons (PAH) in smoked cheeses of different origin was studied. The samples were subjected to an initial extraction of fat and an alkaline treatment, extracted with cyclohexane, cleaned up by means of solid-phase extraction tubes, and analyzed...
