Description
Leaves of Eremanthus crotonoides, Allagoptera arenaria, Byrsonima sericea, Tibouchina sp, Tocoyena bullata and Clusia hilariana were collected under the same climatic in an area of restinga in the Northeast of the State of Rio de Janeiro, Brazil. The activity concentrations of selected radionuclides in the leaves samples were determined. The results obtained have shown a high concentration of 7Be and 40K in E. crotonoides, 210Pb in T. bullata and 137Cs in Tibouchina sp. The high activity concentration of 7Be in E. crotonoides can be explained by the presence of trichomes in the leaves. E. crotonoides and T. bullata reveal high foliar deposition of 7Be and 210Pb, respectively, thus these species can be used as bio-monitors to evaluate the concentration and dispersion of radionuclides in environmental studies
