Heavy metal (Pb, Zn, Cu, Cr, Ni, Mn and Cd) concentrations were investigated for the first time in core sediments of the Municipal Lake of Yaounde, Cameroon. The area under study receives domestic raw sewage from surrounding populated neighborhoods through River Mingoa, main tributary of the lake. Other activities like automobile service stations, garages, non operational effluent treatment sta...

The river Nile is a dominating physical feature of the northeastern part of the African continent, covering areas exhibiting varieties and contrasts in topography, climate vegetation and people. So, in this study, we estimated the contamination of the Nile sediment with some major and trace heavy metals in core samples which can cause some undesirable health effects. Concentrations of all eleme...

Pollutants are persistent in the environment, taint food chain, and harm people's health because of their toxicity. In this study, mangrove snails called Cerithidea obtusa (C. Obtusa) were gathered from Southwest Johor, Malaysia, amounts macro micro elements Ca, Fe, K, Mg, Na, As, Mn, Zn soft tissues, shells, related surface sediments analysed. The Neutron Activation Analysis (NAA) method was u...

Abandoned iron ore mining soil was analyzed for its metal contamination. Pollution indices were calculated and used to examine the potential of area be polluted by metals. The samples collected in triplicate from ten sampling points spread throughout area. energy dispersive X-ray fluorescence (EDXRF) analytical method determine concentrations Cd, Cu, Co, Pb, Zn, Fe, Cr, Ni, Mn. order mean (mg/k...

Heavy metal mobilization in the biosphere by human activities has become an important process in the geochemical recycling of these metals. In this work, 34 soil samples and 29 Tephrosia elegans plants collected in the vicinity of the Diamond Cement Factory, Aflao, Ghana were analyzed for As, Co, Cr, Cu, Mn, Ni, Pb and Zn using energy dispersive XRF. The results of the metal analysis indicated ...

The alteration of hydrologic condition of Three Gorges Reservoir (TGR) after impoundment has caused numerous environmental changes. This study investigated the distribution, accumulation and potential sources of the seldom monitored trace elements (SMTEs) in sediments from three tributaries (ZY, MX and CT) and one mainstream (CJ) in TGR during different seasons. The average contents of most SMT...

The purpose of this study is to recognize the contamination characteristics of trace metals in soils and apportion their potential sources in Northern China to provide a scientific basis for basic of soil environment management and pollution control. The data set of metals for 12 elements in surface soil samples was collected. The enrichment factor and geoaccumulation index were used to identif...

20 soil samples collected from the vicinity of the Khash Cement plant, Iran, were analyzed for As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb and Zn using ICP-OES. The results revealed that the metal distribution were in a fluctuating manner considering various distances and direction from the cement facility. However, it was observed that the mean concentration of the soil samples has no special trend wit...

Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...
