Abstract The paper presents the results of Cr, Co, Cu, Fe, Ni, Mn, Pb, Zn, and four radionuclides (226Ra,232Th, 137Cs, and 40K) determination in transplanted lichens after two, four, and six months of exposure. Lichens were sampled from the area of Mountain Igman in Bosnia and Herzegovina (BiH) and transplanted to two locations (Pofalići and Bjelave) in Sarajevo, the capital city of BiH. The total metals content was determined by flame atomic absorption spectrometry (FAAS). Gamma spectrometry (GS) was used for radionuclide activity determination. Content of Cr, Co, Cu, Fe, Mn, Ni, Pb an Zn in lichen after two, four, and six months of exposure ranged as follows: <LOD-0.61, <LOD-1.55, 3.85–8.08, 332.5–497.9, 19.68–31.65, 2.29–4.24, <LOD-10.30, 32.76–58.58 µg/g, respectively. Cr was not detected in exposed lichen samples. A very strong positive correlation for Cu-Cu, Cu-Fe, Cu-Pb, Cu-Zn, Ni-Ni and Fe-Fe was obtained in lichens, while a strong correlation was between Co-Zn, Co-Cu, Pb-Pb and Mn-Mn. The specific activity of 137Cs ranged from 19.95 to 56.66 Bq/kg, while for 40K ranged from 49.65 to 330.61 Bq/kg. The specific activity of 226Ra and 232Th was below the GS limit of detection.

Metals in red and white wines may stem from both natural and anthropogenic sources, with their concentration serving as an important parameter influencing wine consumption. The objective of this study was to determine the metal content in available wine samples from the Bosnia and Herzegovina market. Eight samples of red wine and seven white wine samples were analysed. Cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) were determined in these samples given their potential impact on wine quality and thus human health. Metal determination was conducted using flame atomic absorption spectrometry (FAAS). Limit of detection values were calculated using two methods for standard solution preparation, utilising distilled water and 10 % ethanol as blanks. Moreover, a human health risk assessment of trace elements present in wine samples was conducted. The concentrations of Cr, Cu, Fe, Mn, and Zn in the samples were found to be below the maximum allowed limits according to the regulations set by the International Organization of Vine and Wine, as well as the national regulations of Bosnia and Herzegovina, the European Union and Croatia. The content of Cd, Co, Ni, and Pb in all wine samples was below the detection limit of FAAS. The data obtained indicated that consuming 250 ml of wine samples appeared to be safe regarding the health risk associated with the potentially toxic metal intake. However, consumers should remain aware of other potential risks associated with excessive wine consumption. Regarding winemakers and the wine industry, to reduce the metal content in wine, monitoring of metal content should extend beyond just the grapes to include soil, air quality at the vineyard locations, and at different stages of the winemaking process since metal content in wine has an impact on the sensory attributes and overall quality of the wine.

In this paper, chemical analysis of slag from abandoned medieval mine in Gornji Potočari, Srebrenica municipality was described. Total of 10 metals were analyzed: chromium, copper, cadmium, nickel, cobalt, zinc, silver, manganese, iron and lead. Traces of chromium, nickel, cobalt, copper, manganese and cadmium in the samples point to the fact that the starting ore also contained these elements. Results showed high content of iron (25.11–33.12%), lead (5.90–10.77%) and zinc (1.16–6.79%). The content of silver had a positive correlation with the content of lead, which is in favor of the initial hypothesis that the starting ore was galena (PbS). High zinc content indicates that the sphalerite (Zn,Fe)S was also used in the process, whereas iron most likely emanates from pyrite (FeS2). Galena and sphalerite can be found in Srebrenica area in large quantities. The results of the analysis show that the site was used for the production of lead and silver (from primary ores), intensive mining activity during the Middle Ages, and the latest date that we can account for slag origin is the end of the 16th century.
