Capacità di accumulo di metalli in una specie mediterranea: Nerium oleander L. a Palermo (Sicilia, Italia)

Abstract

ABSTRACT- Capacity of atmospheric pollutants accumulation of an ornamental mediterranean species: Nerium oleander L. at Palermo (Sicily, Italy) - The role of Nerium oleander L. as bioaccumulator of atmospheric contaminants was studied. Material was collected in six sites of the city of Palermo (Sicily, Italy) every two months from April 1998 to June 2000. Total concentration of Al, Ba, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Zn and V was measured in washed and unwashed leaves. This study demonstrates that there are differences in accumulation capacity amongst the twelve studied elements. This species can not be considered hyperaccumulator of any of the studied elements. High correlation was observed between manganese and barium.
