Assessment of Heavy Metal Pollution Using XRF Spectrometry– A Case Study of Kilimapesa Hill Gold Mines Processing Plant area, Narok County
This study determined the levels of heavy metal concentrations; cadmium, arsenic, chromium, mercury, lead, copper and zinc in environmental samples, to assess the extent of pollution around Kilimapesa. Forty-one samples, from nineteen sites; nine sub-surface soils, eight sediments, fourteen Sodom apple leaves and ten water samples were analysed for heavy metal content using XRF spectrometry. The concentrations levels in water was highest at the confluence of the streams. The levels in soil samples were high compared to World Health Organization standards. The concentrations in Sodom apple were comparable to those found in undisturbed environments, except for arsenic and lead. A significant difference in metal levels among the three media was observed, following ANOVA analyses. Pearson's correlation for the elements in Sodom apple and soils were very weak except for mercury. The same trend was replicated between soils and water, and between water and plants, for all heavy metals of interest in this study, except for Zn and Ni, respectively. Generally, soils are moderately to extremely contaminated. An introduction of heavy metals bio-accumulators in the waste disposal treatment ponds and enforcement of disposal regulations and for epidemiological studies.
