摘要

The aim of this study was to analyse sediments of the selected water reservoirs of Piargs group. Secondly, our purpose was to determine values of exchange reactions in soil of these sediments during the period from 2001 to 2010 and to evaluate environmental hazards caused by the selected potentially toxic elements affected by pH. Based on the results gained by analysis we aim to determine the correlation and statistical significance of dependencies of the analysed environmental parameters. Two different methods, the flow electrochemical method and the atomic absorption spectrometric method have been used to analyse the content of potentially toxic chemical elements in leachate.The analysis of leachate samples, in order to find out the values of exchange reactions in soil, was carried out by potentiometry. Ascertained values of exchange reactions in soil ranged from 5.6 to 7.2. According to the calculated indices of dependencies, the development of pH/KCI values can be evaluated as moderately dynamic. The calculated indices of the Spearman's correlation coefficient for exchange reactions in soil demonstrate statistically significant dependence, especially for zinc and cadmium.
