Toxic metal pollution of waste waters and soils is a major environmental problem, and most conventional remediation approaches do not provide acceptable solutions. The new technologies, phytoextraction, phytoaccumulation, and phytostabilization, make it possible to achieve an effective in-situ reduction of toxic load, especially by choosing suitable plants that have the desired properties. From the rhizosphere of ruderal plants growing on the decontamination area of industrial waste in Ostrava, bacteria with presu...

Bioavailable heavy metals have been extensively studied in recent years because of their toxicity to natural ecosystems. Even though there is a large number of studies, relatively little is known about the biologically available metal fraction. The current study analyses seasonal concentrations of heavy metals associated with reactive fractions (solvable in HCl) in the soil of three areas on West Jiu river. Concentrations of heavy metals identified in indigenous ichthyofauna (Salmo trutta fario) collected from eac...
