Comparison of brown rendzina and colluvial sinkhole soil in the area of the National park “Una” with special emphasis on the distribution of cadmium, nickel and arsenic

The paper presents the results of a comparison of brown rendzina and colluvial sinkhole at approximately the same altitudes and the same land use. The sites were located in the Kalati area within the National Park „Una“. More precisely, the places referred to the top of the sinkhole (brown rendzina - top) and the bottom of the sinkhole (colluvial soil - bottom). The main objective of the research, in addition to the physical and chemical parameters of soil quality, was to determine the distribution of the total content of cadmium (Cd), nickel (Ni) and arsenic (As). The total content of these elements werw observed in composite samples at two depths of 0 – 10 and 0 – 20 cm and horizons profile. Their total content was measured by atomic adsorption spectrometry – AAS. The results were statistically analyzed using Kruskal - Walisovog test at the significance level of p ≤ 0.05 using correlation coefficient χ2. The results showed a single legality of the distribution of Cd, Ni and As in samples of soil profile, while the average soil samples showed unique legality of the distribution of observed elements

Content of Heavy Metals and Metalloids in Drinking Water in the Una-Sana Canton of the Federation of Bosnia and Herzegovina

Unsko-sanska županija bogata je prirodnom izvorskom vodom, kojom se opskrbljuje stanovništvo. Po prvi put je ispitana procjena kakvoće toksičnih i esencijalnih teških metala i metaloida u vodi za piće iz više izvorišta u osam općina i to: Bihaću, Cazinu, Bosanskoj Krupi, Bužimu, Velikoj Kladuši, Bosanskom Petrovcu, Sanskom Mostu i Ključu. U svibnju 2016. godine iz svake općine analizirano je po tri uzorka vode (ukupno 24). Mjerene su koncentracije arsena, olova, kadmija, kroma, nikla, kobalta, molibdena, fosfora, cinka i bakra. U pet uzoraka vode uočene su povećane koncentracije za Ni (do 20 µg dm–3) i Cr (do 50 µg dm–3) i smatraju se prirodnim podrijetlom. Međutim, u većem broju uzoraka (osam) koncentracije As su odstupale od dozvoljenih (do 10 µg dm–3), s maksimumom od 14,05 µg dm–3 i vjerojatno su od samog sastava zemljišta, ali i antropogenih izvora zbog postojanja odlagališta otpada u široj regiji izvorišta. Vrijednosti koncentracija ostalih elemenata Cd, Pb, Co, Cu, P, Mo i Zn bile su u granicama maksimalno dozvoljenih propisanih Pravilnicima u BiH, Direktivom o vodi za ljudsku potrošnju 98/83/EC, kao i smjernicama Svjetske zdravstvene organizacije (WHO). Sadržaj teških metala i metaloida u vodi za piće na području Unsko-sanske županije, osim za As ne predstavljaju opasnost za zdravlje ljudi.

Performed for the first time was a quality assessment of toxic and essential heavy metals and metalloids in drinking water from several sources in eight municipalities: Bihac, Cazin, Bosanska Krupa, Buzim, Velika Kladusa, Bosanski Petrovac, Sanski Most, and Kljuc. In May 2016, three samples were taken from each municipality (total 24). The concentrations of arsenic, lead, cadmium, chromium, nickel, cobalt, molybdenum, phosphorus, zinc, and copper were measured. In a small number of water samples, slightly increased concentrations of Ni (up to 20 µg dm–3) and Cr (up to 50 µg dm–3) were found, and considered to be of natural origin. However, in the majority of samples, the As concentrations differed from the allowed concentration (up to 10 µg dm–3), with a maximum of 14.05 µg dm–3, which probably originates from the very composition of the soil, but also from anthropogenic sources due to the existence of a landfill in the wider region of the source. The concentrations of other elements, Cd, Pb, Co, Cu, P, Mo, and Zn were within the maximum permissible limits prescribed by the Regulations of B&H, the EU Drinking Water Directive 98/83/EC, as well as the WHO guidelines. Except for As, the content of heavy metals and metalloids in the drinking water of Una-Sana Canton is not a danger to human health.

Amino Acids Composition and Antioxidant Activity of Selected Mushrooms from Bosnia and Herzegovina

Many studies highlight the health benefits of mushrooms, which are consequently becoming more and more interesting for researchers. The content of amino acids (AA), total phenolic content (TPC), and antioxidative activity (AAc) were determined in wild as well as cultivated mushrooms. The AA included: L-tryptophan (Trp), L-arginine (Arg), L-cysteine (Cys), L-methionine (Met), L-alanine (Ala), L-phenylalanine (Phe), L-lysine (Lys), L-valine (Val), L-glycine (Gly), and L-leucine (Leu). The wild mushrooms: Lactarius piperatus, Amanita caesarea, Lactarius deliciosus, Lycoperdon pyriforme, Macrolepiota procera, and cultivated mushrooms: Agaricus bisporus, Boletus aestivalis, Cantharellus cibarius, Pleurotus ostreatus, and Agaricus bisporus var. avellaneus were investigated in this study. The AA was determined by HPTLC method and quantified with a Camag TLC scanner and WINCAT software by scanning the plates at 540 nm. The TPC was spectrophotometrically estimated as gallic acid equivalents/g of fresh weight according to Folin-Ciocalteu’s method. The radical scavenging activity (RSA) of mushroom extracts was determined by DPPH assay. The highest content of Ala, Gly, Phe, Lys, Val, and Leu was found in Pleurotus ostreatus. The total phenolic content (mg GAE/g) in investigated mushrooms ranged from 1.90 to 35.56, and the % RSA ranged from 43.88 to 90.17. This study promotes the consumption of food rich in bioactive compounds, mushrooms being among such food. Further research on mushrooms from Bosnia and Herzegovina and their benefits in the overall maintenance of human health and protection from age-related diseases is necessary
