  • Accumulation of heavy metals in the bottom sediments of the Irkutsk Reservoir

    The chemical composition of the bottom sediment, and more particularly the heavy metals content, reflects human developments and impacts on the catchment and reservoir's natural environment. The bottom sediments of the reservoir retained by the Irkutsk Dam have been analysed. The reservoir is mainly supplied by water from Lake Baikal. The following amounts of heavy metals have been found in the ...

  • Industrial ecology for leverage to let loose less cadmium

    Comprehending how humans let toxic cadmium (Cd) loose in their environment demands analysing zinc (Zn) production, the source of most mined Cd. Analysis of unaccounted Cd with the ImPACT identity as a product of population, affluence, intensity of Zn use, and the used fraction of Cd in Zn ore shows that the used fraction exerted the most leverage. A simulation of emission from Zn mining and ...

  • Quantum dots exhibit less bioaccumulation than free cadmium and selenium in the earthworm Eisenia andrei

    This work addresses the bioaccumulation behavior of cadmium selenide quantum dots (QD) by Eisenia andrei earthworms in a terrestrial environment. Earthworms were exposed to QD‐treated soil for up to four weeks, and analyzed for cadmium and selenium concentration using inductively coupled plasma mass spectrometry. Results were compared to earthworms exposed to cadmium nitrate and selenious acid, ...

  • Heavy metal speciation and mobility assessment of arid soils in the vicinity of Al Ain landfill, United Arab Emirates

    Sixty-four surface soil samples taken in the vicinity of Al Ain landfill were analysed for cadmium, chromium, copper, nickel, lead and zinc by inductively coupled plasma spectroscopy. Extraction techniques were used to establish the association of the total concentrations of the six metals in the soil samples with their contents in the exchangeable, carbonate, iron/manganese oxides, and residual ...

  • Removal of cadmium from water using by-product Crambe abyssinica Hochst seeds as biosorbent material

    The effectiveness of Crambe abyssinica Hochst seeds by-product as a biosorbent for the removal of cadmium ions from wastewater was analyzed. The biomass of crambe was characterized by scanning electron microscopy, infrared spectroscopy and determining the point of zero charge. The optimum adsorption conditions obtained were 400 mg of biomass in a solution of pH 6.0 and contact time of 60 min ...
