Note: Rings are the number of benzene rings in the PAH molecule. EPAPAHs are the 16 EPA Priority Pollutant PAHs commonly regulated for the protection of environmental health. Light PAHs (LPAHs) contain two or
three rings and are prone to environmental weathering (Uhler and Emsbo-Mattingly, 2006). Heavy PAHs (HPAHs) contain four to six rings and are less prone to environmental weathering than LPAHs (Uhler and Emsbo-
Mattingly, 2006). Various thiophenes contain sulfur (SPAHs) within the ring structure. Parent PAHs contain no alkylated functional groups attached to the PAH ring structure. The alkylated PAHs (AlkylPAHs) contain
one, two, three, or four carbon functional groups attached to the PAH ring structure. Diagenetic PAHs are formed naturally by oxidation of detrital materials generally composed of land plants. The nominal detection limits
are 10 ng/L in water and 2 µg/kg in solid samples using GC/MS instrumentation.
