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.

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.
