One example of these are polycyclic aromatic hydrocarbons (PAHs) that are considered as priority pollutants by the European Union (EU) and the Environmental Protection Agency (EPA) because they are carcinogenic and they can genetically mutate [3, 5-8] and what is more, these compounds could activate oxidative stress of DNA, hence damaging metabolic activation and the generation of reactive kinds of oxygen [9, 10] making the extraction, preconcentration, and determination of these compounds in the environment very important [11, 12].
In Polycyclic Aromatic Hydrocarbon [PAH.sub.n] with n [greater than or equal to] 1, there are all three types of 3-paths in which degree sequences are (1, 3, 3, 1) (1, 3, 3, 3) and (3, 3, 3, 3), respectively.

Polycyclic aromatic hydrocarbons (PAHs), a group of typical chemicals containing two or more aromatic rings, are widely distributed in water [1],soil, sediment [2-5],and air [6].PAHs have been attracting increasing attention, because many are known to be carcinogenic, mutagenic, or teratogenic [7, 8], which are serious health threats to organisms.
