Abstract:
A study of trace elements using Instrumental neutron activation analysis was carried out. The purpose of study was to determine the concentration of trace elements, naturally occurring radionuclides and pollution Indices. The study Shawa-01 Oil Well is located in Kohat Basin, Khyber-Pakhtunkhwa, Pakistan. The 21 samples of Shawa-01 Well were provided by the Oil and Gas Development Company Limited (OGDCL). 20 trace elements were determined by NAA. Standard reference materials IAEA-SL1 (Lake Sediment) and IAEA-S7 (Soil) were used to assure the quality of results. Shawa-01 Well rock extracts contain trace elements like As, Ce, Co, Cr, Cs, Eu, Hf, K, La, Mn, Rb, Sb, Sc, Sm, Ta, Th and V. Al was found to be higher as compared to other world regions due to clay contents. Other elements were found to be in comparable range. Annual Dose rates were found to be in the safe limit which implies a safe working environment. Pollution Indices, like Enrichment factor (EF), geo-accumulation index (Igeo), Pollution Index (PI) and Integrated Pollution Index (IPI) were also calculated. Elements like Sb, As and Cr show pollution levels above safe limits which may be due to contamination of soil from diferent sources with the passage of time.
