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.
Waste Water Treatment
Jiřičný, Vladimír ; Král, R. ; Vychodilová, Hana ; Vlček, Dalibor
A conventional precipitation method for given composition of waste waters have been modified to diminish content of heavy metals below desired limits.
Heavy metals in parasite-host systems: tapeworm vs. fish
Baruš, Vlastimil ; Tenora, F. ; Prokeš, Miroslav ; Peňáz, Milan
Concentrations of heavy metals in two parasite-host systems (tapeworm vs. fish) were analysed. In the system Ligula intestinalis vs. common bream Abramis brama, white bream Blicca bjoerkna and roach Rutilus rutilus were found in the biomass of plerocercoids mean heavy metal concentrations ranging in Pb 3.20-4.51, in Cd 0.21-0.31, in Cr 1.13-3.16 mg/kg in the 100% dry matter. Regarding the values of accumulation ratio, the parasite accumulated 12.5-18.9 time more Pb, 2.3-3.0 times more Cd, and 4.4-14.1 times more Cr, compared to heavy metal concentrations in the muscles of intermediate hosts.

Miholová, D. ; Száková, J. ; Vysloužilová, M. ; Kolihová, D. ; Pokorný, Jan
Concentration of Mn in sediment, water and plant biomass was studied in eutrophic fishponds of Třeboň Biosphere Reserve.
