in the present study, a field study was performed on some herbaceous plants growing in thesoutheast of ahvaz, where some metal producing industries are active. the aim of this studywas to investigate and compare manganese (mn) and zinc (zn) accumulation in seven dominantherbaceous plants in this area. plant samples were collected randomly. associated soils weresampled from the same sites next t...

background: the aim of this study was to determine bioavailability heavy metal concentrations of cu, cd, cr, co and zn and health risk assessment in different types of klang district, selangor (malaysia) urban surface soil using in physiologically based extraction test in vitro human digestion model. methods: a total of 76 urban surface soil was sampled based on seven different types of land us...

The use of plants to monitor heavy metal pollution in the terrestrial environment must be based on a cognizance of the complicated, integrated effects of pollutant source and soil-plant variables. To be detectable in plants, pollutant sources must significantly increase the plant available metal concentration in soil. The major factor governing metal availability to plants in soils is the solub...

All the regulations that define a maximum concentration of metals in the receiving soil are based on total soil metal concentration. However, the potential toxicity of a heavy metal in the soil depends on its speciation and availability. We studied the effects of heavy metal speciation and availability on soil microorganism activities along a Cu/Zn contamination gradient. Microbial biomass and ...

A novel, cost-effective and eco-friendly technologies are needed to remove Zinc from the contaminated soil environment. The present research study was designed to assess the naturally enhanced phytoextration and phytostabilization potential of different plant species from the Zinc (II) contaminated soil. Uptake of Zinc by plant species in a metal contaminated soil was studied in pot culture exp...

17 To assess the risks that contaminated soils pose to the environment properly a greater 18 understanding of how soil biota influence the mobility of metal(loid)s in soils is 19 required. Lumbricus terrestris L. were incubated in three soils contaminated with As, 20 Cu, Pb and Zn. The concentration and speciation of metal(loid)s in pore waters and the 21 mobility and partitioning in casts were...

The technique of diffusive gradients in thin films (DGT) has been shown to be a promising tool to assess metal bioavailability in soils under laboratory conditions. In this study we used DGT to investigate the resupply kinetics of Cu and Zn under in-situ conditions in a polluted lysimeter soil and compared the results with laboratory measurements using undisturbed soil cores at defined water co...
