“…Hydrogeochemical mapping, an integral part of most regional and local mapping surveys [3][4], is particularly useful in mapping a drainage basin that includes a proposed mine site [5]. The Lom Basin in East Cameroon is heavily mineralized especially in gold owing to its regional geological setting.…”

Abstract:The present study is the first appraisal of regional hydrogeochemical programme for environmental assessment of the mineralized Lom Basin in East Cameroon. Fifty-two streamwater samples were collected and analysed for major cations ( -had similar distribution trends reflecting weathering from the parent rocks. Sulphate distribution correlated with the occurrence of sulphide minerals associated with hydrothermal gold mineralization in the area while the distribution patterns of NO 3 -and Cl -reflected pollution from domestic activities within the municipality. Overall, the chemistry of stream water in the Lom Basin is mainly controlled by silicate weathering with only minor anthropogenic influence. This study forms an analogue for hydrogeochemical mapping in other mineralized terrains in Cameroon.

“…Therefore, river sediments may act both as source and sink of the metals (Varol, 2011). High concentration of HM in environment attracted the scientific community due to its non-biodegradability, long biological half life and toxicity potential (Jain, 2004;Chabukdhara and Nema, 2012;Kelepertzis et al, 2012). In an unpolluted environment, HM are attached to silicate and minerals.…”

“…This relationship is reflected by the increased As concentration in Fe (III) oxy-hydroxides fraction in the oxidation zone of tailings (Dold and Fontboté 2001). Kelepertzis et al (2012) also noted that the low Pb level as 1-The natural adsorption by adsorptive agents such as Fe-oxy-hydroxides that retain trace elements such as As, Pb, Bi and Mo in the solid form; 2-The movement of the released trace elements (Ag, Al, Cr, Se and Sb) from weathering zone and concentrate in the surface evaporative layer.…”

The Toxicity Characteristic Leaching Procedure (TCLP) was applied in order to determine the leachability and mobility of different trace metals and metalloids from the Sarcheshemh Cu mine tailings. Twenty one solid samples were collected from weathered and fresh tailings and also from evaporative secondary minerals and efflorescence salts associated with the oxidation zone of dried tailings. According to the TCLP results, the most leachable and mobile trace elements are Ag, Al, Cd, Ni, S, Se, Co, Cr, Cu, Fe, Mn and Zn. These contaminant elements were concentrated in the surface evaporative layer formed on the top of old weathered tailings. Very high concentrations of Al (27,600 mgL −1 ), Cu (56,900 mgL −1 ), Mn (13,260 mgL −1 ), S (151,800 mgL −1 ), and Zn (3,935 mgL −1 ) were observed in the TCLP results of the evaporative samples (mean values are presented). The results obtained from evaporative and efflorescence samples were higher than the regulatory levels for Al, Cu, Cd, Ni, Se, and Zn. The maximum leachability was found for Al and Cu, followed by Ni, Cd, Zn, and Se. The results of this study are useful for the prediction of contamination potential of trace elements and environmental management of mine tailings.
