Quantification and Distribution of Polynuclear Aromatic Hydrocarbons (PNAs) in Surface Waters in the Vicinity of Kokori Oil Field, Nigeria

摘要

The distribution pattern and sources of sixteen PANs listed as priority pollutants wereinvestigated in eight composite water samples using Gas Chromatography (GC) with a Hawlett-Packard model6890 with 30m x 0.28 capillary column. Analytical observation of the percentage distribution of PNAsconcentration in the study area show thatSSY(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 studyarea show that the Gen. and Car PNAs recorded 29.58% over other PNAs with 70.42%. The percentagedistribution of low PNAs/high PNAs and ratio analysis show that this sources are petrogenic and pyrogenic butdominated with petrogenic PNAs @ JASEM
