Spoil heap toxicity and possibilities for remediation
Venclovská, Lenka ; Frouz, Jan (advisor) ; Lukavský, Jaromír (referee)
The content of this diploma thesis is to verify of possibilities for remediation spoil heap toxicity in Sokolov area, by the help of creating biological crusts. The main question of this work is the possibility of using algae to create biological crust on toxical substrates, which could improve the properties of substrates and contribute to the acceleration of succession. The correctness of this theory was tested using two tests on toxic soils in spoil heaps near Sokolov. In the first test (laboratory test) have been chosen two of the soils and the higher plants, in most cases, even did not germinate. That is why we decided to verify the second option to create biological crust in these phytotoxic soils. Therefore we applied selected kinds of algae in the field, some areas were liming, and the field has been monitoring and sampling during next three years. The results show that the application of dolomitic limestone does not affect progress of biological crusts. The result of the fluorescent microscopy clearly shows, that Klebsormidium algae was the only one of the tested algae, which survived and progressed compact visible crusts.
