Determination of heavy metals in soils and sediments in the region Revúce
Kováč, Lukáš ; Vávrová, Milada (referee) ; Doležalová Weissmannová, Helena (advisor)
This thesis aims to assess the extent of contamination of soil and sediment with risk metals in Jelšava. The main polluter of the environment in this area is the magnetize factory. Sampling of soils and sediments were made in three seasons. Sampling times were staggered to represent different seasons and to take into account the impact of the seasons on the obtained values of the concentrations in soil and sediment. Sampling sites were selected according according to the different distances from the factory and according to the different loading of roads. In each of the collected samples were determined concentrations of the elements copper, lead, zinc, nickel, manganese, mercury, cadmium and vanadium. Copper, lead, zinc, nickel and manganese were analyzed by atomic absorption spectrometry with atomization in a flame (F AAS), cadmium and vanadium were determined by atomic absorption spectrometry with electrothermal atomization (ET AAS). For the determination of mercury was used mercury analyzer (AMA).
