Assessment of environmental and radiological health hazards due to heavy metals and radionuclides contents in utility water reservoirs' sediments
Heavy metals and natural radionuclides in sediments of Awara and Osse reservoirs, Ondo State, Nigeria have been measured using X-ray fluorescence and γ-ray spectrometry techniques. Heavy metals detected in the two reservoirs include K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Ba, Pb and Th. The average concentrations of the measured heavy and trace metals in the sediment of Awara dam vary as Fe>K>Ca>Mn>Ti> Sr>Cr>V>Rb>Zn>Ni>Cu while those of Osse dam vary as Ba>K>Fe>Ca> Mn>Sr>Ti>V>Rb>Cr>Zn>Ni>Th>Pb>Cu. Geoaccumulation index and enrichment factor evaluation of potentially toxic heavy metal contents in both reservoirs revealed that the two reservoirs are uncontaminated with hazardous heavy metals. Naturally occurring radionuclides (40K and 232Th) detected in the two reservoirs show values that are higher than their mean crustal value, while 226Ra is lower than the world mean crustal value. There is little or no ecological or radiological risk associated with the sediment of the two reservoirs.
期刊介绍：
The IJEnvH is a fully-refereed scientific journal that provides an international forum for the exchange of information and the advancement of knowledge in the multidisciplinary field of Environment and Health. The aim of the IJEnvH is to stimulate the discussion and communication among scientists, researchers and experts with different background and expertise, involved, at different levels, with the study of environment and health problems.
