Seasonal concentration changes of trace elements in selected lichen and moss in protected areas in Slovakia
Abstract
In this study, we focused on trace element changes in the lichen Hypogymnia physodes and moss Sphagnum sp. during different seasons in two selected protected areas in the Slovak mountains, which represent a characteristic ecosystem type of Sphagnum spruce forests. Samples were collected during three summer and winter months. The main objective of this study was to determine the relationship of selected trace elements to the seasons and to compare these concentrations between the plant species studied, between areas (Hruštínka and Pavlova) and according to seasons. The results show that lichens accumulate lower amounts of trace elements than mosses. In most cases, pollution was shown to be higher in the winter season than in the summer season. During the winter period, we were particularly interested in sulphur, whose values were higher in the summer period at the Hruštínka site. Overall, the Pavlová site was more polluted, with trace elements mainly of anthropogenic origin.
