Abstract

The monitoring of atmospheric heavy metal and other toxic element depositions by using widespread bryophytes as biomonitors has been widely used. Choosing most appropriate moss species in relation to their accumulation properties is the main goal of this research. The accumulation of heavy metals and other toxic elements by widespread mosses of midland have been studied. The research is focused on assessing accumulation properties of 4 species of terrestrial moss, 4 species of paludal moss and 2 species of epiphytic moss. The concentrations of 32 elements have been determined in moss samples by neutron activation analysis (NAA) and atom emission spectrometry (AES). Interspecies and intraspecies comparison revealed significant differences in accumulation properties. The accumulation capacity of Dicranum polysetum was higher than other terrestrial mosses and Aulacomnium palustre had higher accumulation capacity than other paludal mosses. These moss species have been used for monitoring atmospheric pollutants in an immense territory, particularly for research of transboundary transfer of heavy metal pollution. The accumulation property of epiphytic moss was higher than others. The epiphytic moss could be found on the bark of old trees (aspens, poplars, birch) that are of frequent occurrence in urban areas. Therefore, epiphytic moss can be used for monitoring atmospheric pollutants in an immense territory and for research of atmospheric pollution in industrial centers, inhabited locations as well as assessment of atmospheric contamination in local pollution source.
