This paper describes the concentration of selected heavy metals (Co, Cu, Ni, Pb, and Zn) in the Mamut river sediments and evaluate the degree of contamination of the river polluted by a disused copper mine. Based on the analytical results, copper showed the highest concentration in most of the river samples. A comparison with Interim Canadian Sediment Quality Guidelines (ICSQG) and Germany Sedi...

With the swift advancement of geometric modeling industry and computer technology, traditional generalized Ball curves surfaces are challenging to achieve various complex surfaces. Constructing an interpolation curve for given discrete data points optimizing its shape have important research value in engineering applications. This article uses improved golden eagle optimizer design shape-adjust...

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...

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...

Areas polluted by heavy metals in soil may pose a major risk to human health and ecological environment safety. In this study, 89 samples were collected from four potato producing areas (Libo, Chishui, Panxian Weining) Guizhou Province, China, the concentrations of 9 analyzed measured. The aims study was evaluate pollution index some potato-producing Province using geoaccumulation method, load ...
