Use of pollution indices for evaluation of soil contamination
Čmelíková, Dorota ; Pavlovský, Jiří (referee) ; Doležalová Weissmannová, Helena (advisor)
This thesis focuses on heavy metal contamination of soil and the use of pollution indices for its evaluation. Two regions were selected for assessment and comparison. The chosen heavy metals were mercury, zinc, copper, lead and cadmium. These heavy metals were analysed in 15 samples from Kyjov nad 15 samples from Ostrava. Methods of analysis were AMA-254 and FAAS. The established concentrations were used to calculate pollution indices and for health risk assessment. Pollution in Kyjov was assessed as low to medium without any health risks. Ostrava region was assessed as moderately to highly polluted with a low health risk, especially for children.

Heavy metals contamination of selected Brno city localities
Debnárová, Andrea ; Adamec, Vladimír (referee) ; Doležalová Weissmannová, Helena (advisor)
This thesis is focused on the degree of soil contamination with heavy metals in urban area of Brno. Samples were collected in three periods from October 2009 to March 2010, to represent different seasons and their impact on the concentration of heavy metals in examined soil. Ten locations was chosen, each with different level of concentration, starting with busy traffic area where the concentration of means was high continuing to areas located around habitation or parks. As result four elements were determined in every sample: Cu, Cd, Hg and Pb. Presence of copper and lead were detected by flame atomic absortion spectroscopy (F-AAS) and, cadmium by the help of electrothermal atomic absortion spectroscopy (ET-AAS). For the determination of mercury was used advanced mercury analyzer (AMA).

Assessment of soils using pollution indices
Satola, Ondřej ; Pavlovský, Jiří (referee) ; Doležalová Weissmannová, Helena (advisor)
Subject of this diploma thesis is analysis of selected heavy metals in soils which are exposed to long-time cause of contaminants from metallurgical industry in localities Třinec and Ostrava. For assessment of the contamination, indexes for evaluation of soils were chosen. Those indexes are focusing mainly on rate of enrichment of the soils by selected heavy metals and resulting ecological and possibly health risk for human organism. Within every location, 26 samples were extracted, while every sample extract location, were selected to map the level of pollution around metallurgical plants in the most complex way. The analysis of the samples was done by techniques F-AAS and AMA 254 and established metals were mercury, lead, copper, chrome, nickel, manganese and zinc.

The heavy metal contamination of selected sites in Ostrava
Mihočová, Silvie ; Pavlovský, Jiří (referee) ; Doležalová Weissmannová, Helena (advisor)
This thesis is focused on the assessment of contamination of non-agricultural soils of selected locations in Ostrava of hazardous metals. Selection of locations was based on the stationary pollution source REZZO1. Total 36 collected samples from 12 locations in three times periods between July 2010 and March 2011 that each collection represented a different time period for characteristic emissions conditions. The risk of metals mercury, cadmium, lead, copper and chromium were determined by atomic absorption spectrometry (F AAS, ET AAS, AMA 254).The influence of the distance of locations from stationary sources of REZZO1 on the extent of soil contamination by selected metals was confirmed.

Assessment of contamination in selected locations of Valašské Meziříčí
Dunajská, Sabina ; Pavlovský, Jiří (referee) ; Doležalová Weissmannová, Helena (advisor)
This thesis deals with soil contamination caused by heavy metals in the region of Valašské Meziříčí. The metals analysed were cadmium, chromium, copper, iron, mercury, manganese, nickel, lead, zinc. Metals were determined in 34 samples. The analyses were performed using AMA-254 and AAS methods. Contamination indices were used to assess the contaminated sites and health risks were also assessed.
