Quantification and Distribution of Polynuclear Aromatic Hydrocarbons (PNAs) in Surface Waters in the Vicinity of Kokori Oil Field, Nigeria
Emoyan, Onos Onoriode
Abstract
The distribution pattern and sources of sixteen PANs listed as priority pollutants were
investigated in eight composite water samples using Gas Chromatography (GC) with a Hawlett-Packard model
6890 with 30m x 0.28 capillary column. Analytical observation of the percentage distribution of PNAs
concentration in the study area show that
SSY(20.12%)>SSX(16.75%)>SSZ(16.01%)>SST(14.43%)>SSW(13.24%)>SSU(12.06%)>SSV(6.84%)>SSA(0.55
%). The observed distribution of genotoxic (Gen.) and carcinogenic (Car.) PNAs and other PNAs in the study
area show that the Gen. and Car PNAs recorded 29.58% over other PNAs with 70.42%. The percentage
distribution of low PNAs/high PNAs and ratio analysis show that this sources are petrogenic and pyrogenic but
dominated with petrogenic PNAs @ JASEM
