ABSORPTION OF PB, CU, ZN AND CD TYPE MORUS ALBA L. CULTIVATED ON SOILS CONTAMINATED WITH HEAVY METALS
Ts. Nikolova
Abstract: In recent years, interest in heavy metals and fitoremediatsionnite technologies increases. The fact that phytoremediation can be performed on the spot (in situ) at significantly less cost, determined research in this area as highly relevant.
The purpose of this study was to explore the possibilities of the mulberry tree to be used as fitoremediator contaminated soils with heavy metals. And to establish the accumulation of lead, copper, zinc and cadmium in the root system and aerial biomass (habitus). The results obtained show that increasing the saturation of the roots with heavy metals is increased and the concentration
in the aerial parts - stems, branches, leaves and the most in the mulberry fruit. Heavy metals accumulate in plant parts not significantly affect the growth and development of the species Morus alba L.
