Sažetak
The Prašnik forest, located in the south-western part of the Pannonian Basin (Croatia), is a temperate rainforest and the last remnant of the Slavonian rainforest. As a unique phytocoenosis, it was recognized and protected as a special forest vegetation reserve since 1965. Focus of the present study were soil, mushroom and moss samples from this forest. The principal objectives of the study were determination of (i) levels of metals/metalloids in soil, moss and mushroom samples, and (ii) radionuclide activities in soil samples. The main aims of the presented study were to assess: 1) the influence of pedological substrate on the element composition in mosses and mushrooms, as sensitive bioindicators of air quality and environmental health, and 2) the influence of atmospheric deposition on the soil radionuclide composition in this area. Due to its position in the area of warfare during 1990s, the Prašnik rainforest was mined and until 2015 unavailable to visitors. Other than that, as a highly protected area of great biological importance, it was excluded from human exploitation activities since 1928 and is therefore considered free of anthropogenic influence except for contaminants delivered via natural pathways, air or water. Previous studies confirmed only slight and locally restricted influence of the war activities on the soil geochemistry, while the geochemical composition of both mosses and mushrooms showed a prevailing influence of the local substrate and atmospheric deposition. Results of the multielement analysis were in agreement with the data reported in European Geochemical Atlas (FOREGS) for this area. Slightly higher levels than expected by the FOREGS were observed only for Cd, Pb and Zn. The calculated bioaccumulation factors (BAF=Cmoss or mushroom/Csoil ; C - concentration) suggest slight (BAF=10-2 – 10-1) to moderate (BAF=10-1 – 1) accumulation of majority of elements in both mosses and mushrooms. Only Cu in mushrooms exhibited BAF>1. Anthropogenic radionuclides, 137Cs and 134Cs, were present in all samples and reflect the global contamination of the biosphere caused by nuclear tests and accidents in Chernobyl in 1986 and Fukushima in 2011, respectively. Other detected radionuclides are considered to be of natural origin.
