- Abstract
Chromium concentration was determined, through HR-CS-AAS, in tissular and rhizospheric soil samples from three Poaceae species growing in Romanian ruderal and coastal areas: Hordeum murinum L, Leymus racemosus ssp. sabulosus (M. Bieb.) Tzvelev and Lolium perenne L. Biological Accumulation Coefficients (BAC) were calculated. The highest average concentration was found in L. racemosus (22.21 mg/kg) higher than the 1.5 mg/kg "standard reference" levels, but below the hyperaccumulation threshold (1,000/300 mg/kg) With 0.11-0.54 average BAC, all selected species can be considered as moderate accumulators, with the highest values in L. racemosus. Results show that L. racemosus, although not an accumulator under natural conditions, has a potential for Cr phytostabilization, or enhanced phytoextraction experiments.
