Fuel Characteristics of Flax (Linum usitatissimum) Applied for Phytoremediation of Industrially Contaminated Sites
Šyc, Michal ; Pohořelý, Michael ; Toufarová, H. ; Žáčková, P. ; Punčochář, Miroslav
Expansion of energetic crops growing leads to the need of cultivation of soil that was not used so far. Flax as an energetic crop is possible to grow on insdustrially contaminated sites. Furthermore, heavy metals bioaccumulation ability of flax caused remediation of contaminated soils by moving them to phytomass. This phytoremediation method is called phytoextraction and it is one of the phytoremediation technologies. Fuel characteristics and usability of flax for selected heavy metals (Cu, Pb, Zn, Cd, Hg, Cr, Ni, As) phytoextraction are presented in short-paper.

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.
