Our study aimed at characterizing the Zn phytoextraction potential of a metal tolerant Populus tremula accession in symbiosis with a community of ectomycorrhizal fungi from metal-contaminated soil that is naturally forming mycorrhizae with the experi

Anthropogenic trace element emissions have declined. However, top soils all over the world remain enriched in trace elements. We investigated Pb and Cd migration in forest soils of a remote monitoring site in the Austrian limestone Alps between 1992

European aspen is one of the most widely distributed trees in Central Europe and is a typical early colonizer of poor and disturbed soils. However, little is known about ectomycorrhizal (ECM) fungi in these ecosystems. We examined the ECM community o

Sorption curves are commonly used to predict the partitioning of ions between the soil solid and solution in ion transport and rhizosphere models. We review methods for measuring metal desorption for such purposes, and we illustrate the problems invo

Micro–suction cups made of nylon membranes and polyacrylic tubes with planar geometry of the membrane were designed for repeated sampling of rhizosphere solution at defined distances from a root monolayer. Adsorption tests revealed that the materia

Fractionation of arsenic and other trace elements (TE) in environmental solid samples is usually achieved by application of batch sequential extraction procedures (SEP). In the present work a rotating coiled column (RCC) earlier used mainly in counte

Processes in the rhizosphere of metal hyperaccumulator species are largely unknown. We investigated root-induced changes of Ni biogeochemistry in the rhizosphere of Thlaspi goesingense Halacsy in a rhizobox experiment and in related soil chemical and

Experimental data on rhizosphere characteristics at high spatial resolution are required to improve our knowledge on phytoavailability of nutrients and pollutants. In numerous studies, sectioning using refrigerated microtomes has been employed to obt

Arsenic speciation in soil solutions and soil water extracts was assessed using two different hyphenated techniques, i.e. ion chromatography inductively coupled plasma sector field mass spectrometry (HPIC-ICP-SFMS) and capillary electrophoresis (CE)-

Available tools to study rhizosphere characteristics at a sub-mm spatial resolution suffer from a number of shortfalls, including geometrically and physiologically ill-defined root layers containing soil or other growth medium. Such designs may resul
