ABSTRACT



The aim of the research was to estimate efficiency of monoaecian fibrous hemp (Cannabis sativa L., "Benico" variety) for phytoextracting heavy metals from soil-sludge substrate during anaerobic sewage sludge treatment at non-industrial sites. Hemp is known to be an efficient lead, chromium and cadmium phytoextractor from soils, though these heavy metals cannot be found among plants nutrients. Heavy metals analysis of the substrate has shown that an increase in hemp biomass led to reducing lead, chromium and cadmium concentrations by a factor of six, twelve and nearly three, respectively. The effect was observed in light soil fertilised with sewage sludge and compared against respective metals concentration at the beginning of the pot experiment.

Key words: dewatered anaerobic sewage sludge, hemp, chromium, lead, cadmium, biocumulation.
