Abstract: [cze] [eng]
Táto diplomová práca je zameraná na posúdenie miery kontaminácie pôdy a sedimentu rizikovými kovmi v oblasti Jelšava, v ktorej je hlavným znečisťovateľom životného prostredia magnetizový závod. Odber vzoriek pôd a sedimentov boli uskutočnené v troch ročných obdobiach. Odbery boli rozvrhnuté tak, aby reprezentovali rôzne ročné obdobia a aby bol zohľadnený vplyv ročných období na získaných hodnotách koncentrácie v pôde a v sedimente. Odberové miesta boli vyberané podľa rôznej vzdialenosti od závodu a rôzneho zaťaženie cestnou dopravou. V každom z odobraných vzoriek boli stanovené koncentrácie prvkov medi, olovo, zinku, niklu, mangánu, ortute, kadmia a vanádu. Meď, olovo, zinok, nikel a mangán boli analyzované atómovou absorpčnou spektrometriou s atomizáciou v plameni (F AAS), kadmium a vanád boli stanovené metódou atómovej absorpčnej spektrometri s elektrotermickou atomizáciou (ET AAS). Pre stanovenie ortuti bol použitý analyzátor ortuti (AMA). 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).
