Accumulation of selected risk elements in plants growing in constructed wetlands for wastewater treatment.
VANČUROVÁ, Ivana
The aim of this bachelor work is to provide a literature survey aimed at the accummulation of risk elements by plants growing in constructed wetlands. The results of the survey revealed that less than 2% of the inflowing amount of risk element sis sequestered in the aboveground reed biomass. The highest concentrations were measured in roots while relatively low concentrations were found in rhizomes and aboveground biomass. Concentrations in Phragmites roots were usually higher than those in Schoenoplectus. The accumulation of risk elements was the highest during winter for Phragmites and in autumn for Schoenoplectus. Both plant species were found to be root accumulators of Pb, Cu, Mn, Ni, Zn and Cd.
Evaluation of selected risk elements removal processes from wastewater in constructed wetlands.
MRÁZKOVÁ, Ivana
The purpose of this bachelor work is to provide a literature survey aimed at the processes responsible for removal of selected risk elements (arsenate, lead, nickel, Merkury, kadmium and manganese) during the wastewater treatment in constructed wetlands. Also, constructed wetlands are compared with conventional treatment plants.
USING BIOACCUMULATION EFFICIENCY OF AQUATIC MOSSES FOR BIOMONITORING SELECTED RISK ELEMENTS IN SURFACE WATERS
BEDĚRKOVÁ, Ivana
The aim of the bachelor work was a complete literary compilation of the theme of using bioaccumulation efficiency of plants, especially water mosses, for a biomonitoring of the occurrence of heavy metals and some other risk elements in surface waters. Water mosses are useful for biomonitoring, some vascular plants gain ground in decontamination of waste waters.
Phytoremediation of radionuclides and metals in soil and waste waters
Soudek, Petr ; Valenová, Šárka ; Plojhar, V. ; Vaněk, Tomáš
Heavy metals and radionuclides are not chemically degradable and possibility of their removing by in situ methods is limited. In the last years are increasingly used plants not only for biomonitoring, but also for remediation.
