ABSTRACT
Salt mining waters are characteristic for deep mining in the Ostrava - Karviná district, located in the Czech Republic. Due to their high mineralization and associated salinity, they may cause salt stress in some organisms. However, there are halophytic plants that are adapted to high salinity and they can withstand the salt stress.Common reed is classified as a halophytic plant and after long-term research it was confirmed to have phytoremediation ability. Phytoremediation is a technology that uses green plants to remove, accumulation or decompose contaminants in the environment found in groundwater, surface water, sediments soil, sludge. Phytoremediation processes in salt mine waters were experimentally tested in laboratory conditions on hydroponically grown reeds. The reduction of the salt concentration in the water samples from the hydroponic system, together with other chemical parameters, was monitored. For comparison, the experiment was also performed on common reed hydroponics taken from the mine Lazy, that are adapted to salt mine water, and common reed hydroponics taken from pond reeds, that are not loaded with high salt concentrations. It was prove by research that the common reed is able to work as root zone wastewater treatment plant for salt waters (not only salt mine waters) and it is able to withstand salt stress.
