Investigation of sequential chemical extraction of arsenic from sediments: variations in sample treatment and extractant
The sequential leaching of As using wet and dry sediment does not reproduce the same results due to changes in redox conditions, organic matter mineralization, and net desorption reactions resulting in phase dispersion during drying......

The rengen grassland experiment: relationship between soil and biomass chemical properties, amount of elements applied, and their uptake
The concentrations of P and K in the plant biomass were positively related to P and K application and, therefore, to plant available P and K concentrations in the soil. The concentrations of some micro (Fe, Mn and Zn) and trace (As, Cd, Cr, Ni and Pb...

The Rengen Grassland experiment: bryophytes biomass and element concentrations after 65 years of fertilizer application
Fertilizer application affects not only vascular plants but also biomass production and species composition of bryophyte communities as well. In low productive grasslands, bryophyte layer cannot be overlooked in element budgets calculations. As the c...

Mobility of arsenic and its compounds in soil and soil solution: The effect of soil pretreatment and extraction methods
The effect of soil extraction procedures and/or sample pretreatment (drying, freezing of the soil sample) on the extractability of arsenic and its compounds was tested. In the first part, 5 extraction procedures were compared with following order of ...

A comparison of arsenic mobility in Phaseolus vulgaris, Mentha aquatica, and Pteris cretica rhizosphere
The ability of Phaseolus vulgaris, Mentha aquatica, and Pteris cretica to release arsenic (As) species from contaminated soil was tested in rhizobox experiments in three soils differing in their physicochemical parameters and total and mobile As conc...

Isotopic composition of lead in Czech coals
The content, forms of bonding and isotopic compositions of lead (Pb) were studied on selected coal samples from the Czech Republic. Lead in most samples of bituminous and brown coal is mobilized by 3 M HCl. Thus, Pb could be bonded in carbonates and ...

Mineralogy and environmental stability of slags from the Tsumeb smelter, Namibia
Three types of smelting slag originating from historically different smelting technologies in the Tsumeb area (Namibia) were studied and differences in mineralogy of different slag types were described. Arsenic in slag leachate exceed the EU regulato...

Effect of Low Concentrations of Phosphate Ions on Extraction of Arsenic from Naturally Contaminated Soil
The effect of low concentrations of phosphate ions on the extraction of arsenic was tested on naturally contaminated soil (As 126 mg/kg) using batch experiments. Interaction entails the extraction of low concentrations of As (5.4?23.3 ?g/l As). There...

Mineralogical and geochemical controls of arsenic speciation and mobility under different redox conditions in soil, sediment and water at the Mokrsko-West gold deposit, Czech Republic
Naturally contaminated soil, sediment and water at the Mokrsko-West gold deposit, Central Bohemia, have been studied in order to determine the processes that lead to release of As into water and to control its speciation under various redox condition...

The effect of immobilization measures in multielement contaminated soil on element uptake by selected crops
The effect of lime, limestone, and zeolite addition on the availability of As, Cd, Cu, Pb, and Zn in 3 contaminated soils have been investigated in a pot experiment in 2 vegetation periods of spring wheat and spring barley. The results showed differe...
