Analysis of the phytotoxic effect of leachates from the landfill of municipal waste in Zdounky on higher plants

Original language description

Municipal solid waste landfills represent sources of anthropogenic pollution of the environment. Waste degradation gives rise to leachates, which are source of pollutants. Landfill leachate are processed by using various methods. One of them being return of leachates into the landfill body, other methods include purification of leachates in the wastewater treatment plant, and there are also newly emerging trends of leachate processing by using the method of phytoremediation. Phytoremediation is a technology of gentle removal of pollutants from the environment by means of higher plants. Reasons for the development of this method lie mainly in achieving lower costs of decontamination. We performed a flowerpot test to demonstrate that ecotoxicity of leachates from the landfill can be reduced. In the test, we assessed the vitality of white mustard (Sinapis alba L.). Pollutants monitored in this research were primarily heavy metals. The dilution of added leachate were 20%, 50%, 75%, 90% and 100%. The goal of this work was to describe the response of white mustard (Sinapis alba L.) to the application of leachate during the simultaneously conducted targeted experiment focused on increasing the phytoremediation potential of white mustard (Sinapis alba L.) and on increasing affinity of heavy metals by the plant by using controlled LED illumination. Based on the research, the positive effect of LED lighting on the biomass growth of the white mustard (Sinapis alba L.) was apparent. The highest growth stimulation occurred at a dilution of 20% of added leachate. It is clear that LED lighting had a beneficial effect on biomass growth and plant vitality compared to the natural lighting experiment.
