Abstract

This work is about evaluation of capacity for some heavy metals uptake and bioaccumulation factor at Polytrichum commune, Elodea canadensis and Spirogyra sp. harvested from Tisa rivulet valey, County Dambovita. Were determinated the concentrations of chromium, lead, strontium, copper, zinc, cobalt, manganese and iron from plants and substrate (mud) by EDXRF (spectrometry of fluorescence) method. For example chromium concentration in Polytrichum commune was 2040 ppm, comparatively to 2990 ppm in Elodea canadensis. Also was calculated the bioabsorption factor for each case. Bioabsorption factor value was very higher for cobalt (1239%) at moss species, for lead (1613%) at Elodea canadensis and for iron (1025%) at Spirogyra sp.
