Víceprvková analýza mechů pro hodnocení vlivu hutní výroby na kvalitu ovzduší

Abstract

The aim of the Bachelor thesis is to conduct a multi-element analysis of moss and assess whether the emissions of heavy metals from the metallurgic plant affect the content of the elements in moss. The collection of moss was carried out around Třinecké železárny in two campaigns, in June and October. Altogether, 14 samples were collected from each period. In the moss samples, the following elements were specified for Al, V, Cr, Mn, Fe, Ni, Cu, Zn, Cd, Pb, As, Sb and Hg. The moss analysis was performed using the ICP-AES, AAS and the AMA 254. The results from the analyses confirmed the impact of heavy metal emissions on the content of moss elements. Increased concentrations of Cr and Pb have shown an impact of the emissions from two sources of pollution, from the steelworks and blast furnaces. As an additional source influencing the concentration of elements in moss, a high furnace was identified due to increased concentrations of these elements Zn, V, Ni, which are typical for a blast furnace. The highest concentrations were found in Fe, which comes from emissions of agglomeration processes.
