KEYWORDS: Toxicity, polycyclic aromatic hydrocarbons (PAHs), carcinogenic, mutagenic, teratogenic and NESREA.
ABSTRACT:Produced water from three Rivers State Community flow-stations (Umuechem-sample A, Umuebulesample B and Egbede ll-sample C) 6-8miles apart were analyzed. They were found to contain 42.48ppm polycyclic aromatic hydrocarbon (PAHs) for sample A, 6.75ppm sample B and 90.79ppm sample C. Oil and grease content was 9,456ppm sample A, sample B 1,155ppm and sample C 17,742ppm. Turbidity (NTU) of sample A was 66.00, sample B 55.00 and sample C 49.00. The pH values of the three samples were found to be 8.10 samples A, B 8.20 and C 8.30. BOD and COD were (790.00, 760.00 and 1,411.00 ppm) and (157.00, 152 and 282 ppm) respectively for samples A, B and C. Total organic carbon (mg/l) was 55.31, 124.00 and 361.00 for samples A, B and C respectively. The metal concentrations of iron, zinc, nickel, cadmium and lead were higher than acceptable limits of National Environmental Standard and Regulation Enforcement Agency (NESREA) while copper; chromium and manganese were within (NESREA) acceptable limits.
