The use of bioaccumulation capabilities aquatic plants and moss for monitoring some risk elements in the Malše river.
BEDĚRKOVÁ, Ivana
The aim of the graduation theses was the using bioaccumulation efficiency of plants, especially water mosses, for the monitoring of the occurence of risk elements in surface waters. The graduation theses assess the content of risk elements in this bioindicators in relation to quality of water supply river Malše. Water mosses susceptibly reflect the statement of water environment and they confirm very good quality of water in river Malše and its usability as water supply river in term of content of monitored risk elements (chrome, arsenic, zinc, lead, cadmium, mercury and uranium).
