Abstract
The
aim of the study was to evaluate the efficacy of the multiflora rose
var. 'Jatar' (Rosa multiflora Thunb. ex Mur) and the Virginia fanpetals
(Sida hermaphrodita Rusby) to phytoextract heavy metals from municipal
sewage sludge. The 6-year field experiment involved four levels of
fertilization with sewage sludge at doses of 0, 10, 20, 40, and 60 Mg DM
sludge · ha-1. The increasing doses of sewage sludge were
found to increase significantly the yield of multiflora rose and
Virginia fanpetals biomass. They also significantly elevated the content
of heavy metals in these plants. The highest uptake of heavy metals by
the multiflora rose and Virginia fanpetals crops was recorded at the
fertilisation dose of 60 Mg DM · ha-1. Our investigations
show that the Virginia fanpetals was more efficient in phytoextraction
of Cr, Ni, Cu, Zn, and Cd from the sewage sludge than the multiflora
rose, due to the greater yields and higher heavy metal uptake by the
former plant. In turn, the multiflora rose phytoextracted greater
amounts of Pb from the sewage sludge. The analyses indicate that the
Virginia fanpetals can be used for phytoremediation (phytoextraction) of
heavy metals contained in sewage sludge.
