Abstract The paper presents the results of research into toxic metal concentrations in surface layer bottom sediments Lake Gopło. objectives were to identify levels and spatial variability Cu, Pb, Cd, Zn, Ni, Cr, As Hg concentrations, their potential sources determinants pollution levels. Metal contamination was assessed using geoaccumulation index (Igeo), load (PLI) ecological risk (RI). Chemo...

Heavy metal(loid)s (HMs) contamination in agricultural soil and crops is related to the quality safety of products public health has attracted worldwide attention. This study systematically investigated bioaccumulation HMs including Cd, Pb, Cr, Hg, As Se associated (Tea, Plum Corn) Guizhou Province, China, assessed risks edible part using bioconcentration factor (BCF), geoaccumulation index (Ig...

The lake management strategy of sediment dredging (removal) is periodically undertaken in shallow, eutrophic Mogan Lake, an important recreation area. This study aims to use certain indices - enrichment index (EF), contamination/pollution (CF), degree contamination (Cd), pollution load (PLI), geoaccumulation (Igeo), potential ecological risk (Eri), integrated (PER), and mean probable effect con...

Accumulation of trace metals in sediment can cause severe ecological impacts. The present study determines the elemental concentrations and chemical partitioning of heavy metals in surface sediment of Shadegan wetland. Shadegan wetland is one of the most important wetlands in southwest of Iran and it is in Ramsar-listed wetlands. For this purpose, 7 sampling stations were selected for sediment ...

Irrigation food crops are intensively cultivated on/or around the abandoned tin mine areas in Plateau State, Nigeria. Vegetables on contaminated soil a potential risk to human health, particularly, through consumption. The physico-chemical properties of and sediment revealed that soil/sediment were acidic, non- saline low fertility. Most heavy metals’ concentrations agricultural soils above DPR...

Abstract Purpose The study aims to assess the impact of human activity on content and migration trace elements in soil profiles various physico-chemical properties. research hypothesis assumed that related functioning buildings, agriculture, industry communication negatively affected element contents properties soils a selected urban area (the Grudziądz Basin). Materials methods Seven exposures...

The soil heavy metal pollution around the mine threatens crop growth and human health. Intensively studies of distribution characteristics source metals some typical mines are very crucial for environmental management green development mine. A total eighty-nine samples, twenty-one sediment five waste rock samples two tailing sand were sampled to investigate copper (Cu), lead (Pb), zinc (Zn), ar...
