This paper examined the efficiency of artificial neural network (ANN) and multivariate linear regression (MLR) models in prediction groundwater quality parameters such as ecological risk index (ERI), pollution load (PLI), metal (MPI), Nemerow (NPI), geoaccumulation (Igeo). 40 samples were collected systematically analyzed for mainly heavy metals. Results revealed that adopting measured is effec...

Recently, one of the major environmental issues is pollution soil with Antimony (Sb), which ecologically detrimental and potentially carcinogenic to humans. In developing countries such as Iran, Sb concentrations in soils have not yet been accurately determined. Therefore, purpose this study was examine levels other HMs (Pb, Cd, As, Ni, Hg Cr) surface Bojnourd, well their distribution potential...

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 impact of heavy metal contamination caused by human activities on mangroves, rivers, estuaries, and coastal wetlands has gained attention recently. In this study, the presence metals in mangrove Sepang Besar River's surface sediments was examined. As, Mo, Pb, Cr, Co, Cd, Ni, Hg concentrations sand were measured using inductively coupled plasma mass spectrometry (ICP-MS). Across all sampling...

Soils in the Lower Swansea Valley, (United Kingdom) contain elevated level of metals, enough to cause direct or indirect effects on human health. This study assesses severity soil pollution and bioavailability Cu other metals (Ni, Zn, Co, Pb Cr) soils with various distances from a Ni refinery. We compare concentrations operationally defined fractions (bioavailable, bound Fe/Mn oxide incorporate...

Mercury (Hg) is a global and widely distributed heavy metal pollutant. can affect human health as well the of ecosystems poses ecological risks. The subjects this study are three types grassland in Beidianzi region, Songnen Plains, Northeastern China, characterized by different degrees degradation. mercury content levels atmosphere, soil, forage grass on grasslands were determined. In addition,...
