ABSTRACT: The levels and
compartmentalization of Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni,
Zn, As, Se, Br, Rb, Sr, Mo, Sb, I, Cs, Ba, La, Ce, Sm, Eu, Tb, Hf, Ta, Au, Th,
and U in Phragmites australis (Cav.)
Trin. ex Steud., Carex conescens L.
and Cladophora sericea (Hudson)
Kutzing from the Caucasian coast of the Black Sea-Anapa recreational region was investigated by
Neutron Activation Analysis. The study touches upon subject of the
sediment-to-plant and root-to-leaf elemental transfer as well as of the
influence of anthropogenic pollution on wetland ecosystems in zone of resort.
The content of the majority of considered elements was found higher in the
belowground organs of P. australis than in the aboveground tissues while a reverse regularity was evidenced for C. conescens. The levels of elements
decrease from bottom sediments to aquatic plants with the notable exception of
the halogens Cl, Br and I that presented 5 to 100 fold higher content in plants
than in sediments. The increased levels of As, Mo, and Sb in some soil and sediment
samples most probably indicate the anthropogenic pollution. It recommends them
for a continuous monitoring of the same area.
