Using Compost, Zeolite and Calcium Oxide to Limit the Effect of Chromium (III) and (VI) on the Content of Trace Elements in Plants

Abstract

kg−1 of soil as well as compost, zeolite and CaO additives on the content of heavy metals in the spring oilseed rape (Brassica napus var. oleifera) and yellow lupine (Lupinus luteus L.). The contents of heavy metals (Cr, Zn, Ni, Cu) in plants, were determined using the method of spectrophotometry. All of the investigated element contents in the tested plants differed significantly in the case of applying amendments to the soil, as well as increasing concentrations of Cr(III) and Cr(VI). In the series without additives in soils containing Cr(III) and Cr(VI), rapeseed was characterized by a higher average content of Cr than yellow lupine. Compost most noticeably limited the negative effect of chromium. Cr(VI) modified the contents of trace elements in the tested plants more significantly than Cr(III).

Environmental Impact of Landfill on Soils – the Example of the Czech Republic

“…The contamination of the soil environment is a more and more frequently occurring problem throughout the world (Sas et al 2015). The observed changes in the chemical composition of soil and plants are the consequence of the contamination of individual components of the natural environment by progressing and degrading anthropogenic activity , Sas et al2015, Radziemska and Wyszkowski 2017. This is why it is necessary to research how the soils are affected by the use by the human societies .…”
