Influence of Filtration Waters of the Solid Municipal Waste Landfill on Biomass and the Elemental Composition of Barley Plants
Under the conditions of a model experiment, the effect of increasing doses of the solid municipal waste landfill filtrate on the biomass of barley plants and the distribution of nitrogen and heavy metals (HM) (Cr, Cd, Li, Pb, Zn) in the soil-plant system were studied. The dependence of plant biomass in the range of filtrate doses of 0–260 ml/kg of soil is represented by curves with a maximum. The N content in the aerial parts of plants linearly increased in the range of tested doses of the filtrate. A tendency to increase the content of HM in the soil was observed. The transition of HM from soil to plants depended on the dose of the filtrate, the degree of cultivation of the soil, and the properties of chemical elements. The content of all tested HM in the roots significantly exceeded the content in the aerial parts of plants.
