Fytoremediácie využitie technických plodín

This bachelor thesis summarize options for using plants, mostly technical crops, for decontamination of soil, water and sludges. This work describes overview and methods of intake of contaminants which may be removed from environment by phytoremediation, description of phytoremediation technologies and their pros and cons, description of crops and limits for theirs use in phytoremediation. In next part of my thesis I describe my experiment on phytotoxical effect of landfill leachate on different parameters of two cultivars of hemp (Cannabis sativa L.). Goal of this experiment was to find optimal concentration of landfill leachate for irrigation. Optimal irrigation is when phytotoxical effect doesn´t excessively inhibit for phytoremediation important parameters of plants, or concentration which don´t exterminant plants immediately after irrigation. Landfill leachate generation is a major problem for municipal solid waste landfills. Leachate causes serious threat to surface water and groundwater. Leachate can be defined as a liquid that passes through a landfill and has extracted dissolved and suspended matter from it. This liquid originate in precipitation which fall on the landfill site and from moisture that exists in the waste when it is composed. Leachate varies widely in compositions depending on the age of the landfill and type of waste that it contains, usually it consists organic pollutants and also heavy metals
