Cím:Theory of phytoremediation and its Hungarian practice / Lakatos Gyula, Keresztúri Péter, Csatári István, Tóth Albert
Dátum:2008

Megjegyzések:Phytoremediation, i.e. recovering the health of soils or sediments contaminated with heavy metals by usinggreen vegetation has today been a stimulating challenge for research and solutions in environmental protectionall over the world. Among the phytoremediation processes, it is the in-situ inactivation technique that hasspecial significance, since it reduces the dangers caused by the potential toxic impacts of heavy metals. Dueto the vegetation providing green surfaces, the phytoremediation processes are environmentally friendly andcost-effective (10-12% percent of traditional methods). This paper presents the results of the floristical andvegetation examinations performed in the units of a former secondary sedimentation pond system in Hungary.The outcome of analyses on the chromium content of the plants will also be discussed.

Cím:Element Composition Of Rosa Canina And Rubus Fruticosus Fruits At An Abandoned Metalliferous Minesite In N-Hungary / Albert Tóth, Mihály Braun, Zsuzsa Tóth, Dénes Gór, Gyula Lakatos
Dátum:2008
Megjegyzések:We studied the element composition of wild-grown Rosa canina L. and Rubus fruticosus L. fruits at a derelict lead-zinc ore mine in North-Hungary. Whole rosehips and Rubus berries were collected from seriously contaminated vs. background spots and analyzed according to standard lab procedures. The species differed in all focal elements except Ba and S. Rubus berries in general were richer in most macro- and microelements, particularly of Mn, Ca, Cu, Sri, Zn, Fe and Ni. The sampling site had a significant effect on all elements except Ca, Cu and Se. Rosehips had very low Cd (< 0.08), As (< 0.12), Pb (< 1.63) concentrations (mg kg(-1) dw). Ba, Cd, Mn, Ni and Sri were found to accumulate consistently in both species' fruits at the contaminated sites. The element composition of entire fruits was shown to be an inadequate indicator of elevated heavy metal levels in the soil in a situation where marked acidification associated with pyrite oxidization is an important process.N2 - We studied the element composition of wild-grown Rosa canina L. and Rubus fruticosus L. fruits at a derelict lead-zinc ore mine in North-Hungary.
