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
