Abstract

The reawakened interests beamed on the prevalence of polycyclic aromatic hydrocarbons (PAHs) concentrations in urban soils remains a serious embodiment to developing countries like Nigeria despite their noxious effects, carcinogenic, mutagenic, teratogenic and endocrine perturbation. The goal of this research is to determine the level of PAHs in soil surface of five dumpsites in Yenagoa Metropolis, Bayelsa State, Nigeria. Concentrations of individual PAHs were analyzed using Gas Chromatography Techniques (ASTM) FID Model SN 6890N (America Society for Testing Materials 20th Edition). The total concentrations of PAHs gotten between the depth of 0- 10cm was 38.3151 mg/kg for Amarata, 55.3406 mg/kg for Ede-pie, 84.8949 mg/kg for Ekeki, 25.0972 mg/kg for Okaka and 57.0769 mg/kg for Onopa wastes dumpsites respectively. Most of these concentrations were far much higher than the Dutch guideline maximum limits of 40 mg/kg. The results showed that the highest concentration of a single PAHs compound was at Ekeki estate waste dumpsite with chrysene value of 22.095 mg/kg and 12.888 mg/kg as the second highest for fluoranthene at a depth of 0-10cm respectively. The Diagnostic ratios of PAHs account for about 5.078-44.151% of the total PAHs detected in the dumpsite raising concerns of human exposure through the food web.
