<p>Estmating the risk to pulic health from heavy metals can help solve the basic questions about the potential dangers of exposure to them. This is the first study aimed to assess the health risk for the residents of the municipality of Zenica, on the land closest to the steel industry by examining the heavy metals Zn, Ni, Pb, Cd, Cr and Cu in the soil and plant cultivars corn and chard that could be used for the potential remediation of such soil. With the calculated data for HQ and HI, the non-carcinogenic and carcinogenic risk for adults and children were estimated, based on heavy metals in the selected topsoil and plants, which are usually grown in the area of interest, through different ways of their intake. The results showed that there is an unacceptable risk for children and adults due to long-term consumption of investigated plant cultivars from soil contaminated with heavy metals. Constant monitoring and measures to reducing the heavy metal pollution, primarily Cd, Pb and Cr, are necessary in the lands of the municipality of Zenica. Special caution is required for residents who intend to grow plant cultivars near steel industry</p>
Polymeric materials have an important role in gluing technology due to their broad application in the wood industry, metal industry, glass, and ceramics industry as well as medicine. This article discusses the basic physicochemical aspects of bonding with adhesives and also, the mechanisms of action of the adhesive materials during bonding based on polymerization processes and different types of polymerization. It was emphasized that depending on the material used in gluing, various adhesives with different physicochemical characteristics facilitate and contribute to the quality of the bonded joints. In this way, it is an insured procedure that is suitable for materials that are sensitive to the effects of heat, because welding and soldering would deform the base material and often the total degradation of its mechanical properties.
: Antigenotoxic and Antioxidative activites of Curcumin Modern biomedical science has proven beneficial effects of curcumin as potential therapeutic candidate for various conditions due to its pleiotropic and pharmacological properties. The aim of the present study was to investigate antigenotoxic effects of curcumin against cisplatin induced genotoxicity as well as its antioxidative effects. In vitro cytokinesis block micronuclei assay in human lymphocytes was used for evaluation of antigenotoxic properties of curcumin. Evaluation of antioxidative properties of curcumin was determined with 2,2-Diphenyl-1-picrylhydrazyl free radical scavenging assay. Results demonstrated significant antigenotoxic and antioxidative properties of curcumin, dependent upon the tested concentrations. Consideration should be given to performing a study with broad dose interval of tested substances. Findings from the present study emphasized application of curcumin as potential antigenotoxic and antioxidative supplementary agent.
The content of macro- and microelements in dry samples of mushrooms of the species Macrolepiota procera, Boletus edulis and Cantharellus cibarius, collected at different areas in Bosnia and Herzegovina, was determined using the ICP-OES method (inductively coupled plasma optical emission spectrometry). Of the macroelements, K is the most represented, followed by S, P, Mg, and the least represented Ca and Na. Zn is the most represented of the essential microelements, followed by Fe, Se, Cu, Mn and Co. Al is the most abundant of the other trace elements followed by Ni and Cr. Of the toxic metals, the most represented is Cd, followed by Pb and As. There are differences in the concentration of micro- and macroelements in the mushrooms analysed, depending on the area from which they were collected because natural geology and geochemistry influence the content of macro- and microelements in wild edible mushrooms. The results show that the analysed mushrooms can be considered a good source of essential elements. The study also assessed potential health risks of heavy metals and the target hazard quotient (THQ) for As, Cd, Pb, Cu, Zn, Ni and Cr in the analysed mushrooms was lower than the safe level. The carcinogenic risk index revealed that Cd and Ni are the most prevalent pollutants in the mushrooms studied.
