Sažetak
Mountains are considered as one of the most sensitive ecosystems to climate changes which may be affected at a very faste rate. These changes may directly and/or indirectly affect organisms, thus native organisms may be used as indicators of different environmental alterations. Mosses are considered as effective air quality bioindicators because they have no roots, no cuticle, and acquire all their nutrients from direct exposure to the atmosphere. Thus, in this study mosses are used as an indicator of trace elements air pollution. Samples of Brachythecium rutabulum and Hylocomium splendens were collected during dry and rainy period in 2016 from 5 sampling sites in the Risnjak National Park. Cd, Cr, Pb and Zn concentrations in moss tissue were analysed by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES Vista MPX AX, Varian), and Hg with Cold Vapor Atomic Absorption Spectrophotometry (FIMS 400, Perkin-Elmer). The concentrations were in range: Cd from 0.2 to 0.58 mg kg−1, Cr from 0.5 to 27 mg kg−1, Hg from 0.036 to 0.136 mg kg−1, Pb from 3.0 to 8.2 mg kg−1 and Zn from 8.6 to 82 mg kg−1. Higher concentrations were measured in B. rutabulum and the samples collected in rainy season at higher altitude. Compared to the results from recent biomonitoring studies of trace metal pollution in the mountain ecosystems, deposition of atmospheric Cd, Cr, Hg, Pb and Zn in mosses in Risnjak National Park may be considered as minor to negligible.
