Cím:Cadmium and Zinc uptake of rye-grass as related to soil type and different land use / Szilárd Szabó, Csaba Ágoston, Mihály Braun, Péter Keresztúri, György Szabó
Dátum:2008
Megjegyzések:The results of a small-pot experiment of cadmium-loading (5 mg kg(-1)) with the addition of zinc (5 mg kg(-1)) carried out are introduced in this paper. For this, soil samples were taken from 4 sites of plough-land, grassland and forest land-use types. Accumulation characteristics of the two metals as well as their interaction with the soil properties were analysed. The results show that land-use has significant effect on zinc uptake. There is close correlation between the zinc and cadmium uptake of plants as well as that cadmium concentration of soils plays in important role in it. Zinc shows positive correlation while cadmium shows negative correlation with organic matter. Beside organic colloids, inorganic colloids i.e. clay fraction also showed close correlation.N2 - The results of a small-pot experiment of cadmium-loading (5 mg kg(-1)) with the addition of zinc (5 mg kg(-1)) carried out are introduced in this paper.

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.
