Persistent organic pollutants (POPs) are chemicals of global concern due to their potential for long-range transport, persistence in environment, ability to biomagnify and bioaccumulate in ecosystems, as well as their significant negative effects on human health and the environment. In this study, seven targeted polychlorinated byphenils (PCBs, IUPAC Nos. 28, 52, 101, 118, 138, 153, and 180) and the organochlorine pesticides (OCPs) aldrin, dieldrin, endrin, cis-chlordane, trans-chlordane and oxy-chlordane were quantified in European date mussel (Lithophaga lithophaga L., 1758.) collected from the Sarajevo fish market (Bosnia and Herzegovina). This slow-growing species is widespread along the whole Mediterranean rocky coastline. In Bosnia and Herzegovina (BiH), this species has not been protected by law and the date mussel harvested in the area of the Neum bay (Adriatic sea) could be found in free sale on BiH market. Applied gas chromatography and tissue extraction methods were validated in the NIVA laboratory. Our samples (n=61) were 4.5-8.4 cm in length. Total OCPs in the analyzed samples were low (ranging from non-detectable to 0.419 µg kg-1 w.w.), while Σ7PCBs was ranging from 20.26 to 135.37 µg kg-1 w.w.. PCBs 101, 118, 138 and 153 were dominant congeners in all samples.

Phenolic contents of methanolic extracts prepared from leaves and fruits of Crataegus monogyna Jacq. and Crataegus macrocarpa Hegetschw. were determined. The antioxidant capacity was assessed by DPPH, ABTS and FRAP assay. The results showed that leaves were richer in the content of phenols (59.23 91.91 GAE g-1), flavonoids (2.38 4.08 mg QE g-1 and 5.24 8.9 mg RE g-1) , phenolic acids (33.40 68.98 CAE g-1) and proanthocyanidins (26.15 48.60 CE g-1) while in fruits anthocyanins dominateted (0.43 0.80 CG g-1). Leaves also had higher antioxidant capacity than fruits for both species. Generelly, C. monogyna fruits had higher content of anthocyanins. Total phenols, phenolic acids and proanthocyanidins were highly corelated with DPPH (r2 = 0.8703 0.9618), ABTS (r2 = 0.7833 0.9443) and FRAP (r2 = 0.903 0.9695) assay. The results suggests that these compounds were the major contributors to the antioxidant capacity in leaves and fruits extracts of both species. Higher contents of bioactive compounds and higher antioxidant capacity were determined for C. x macrocarpa samples. Therefore, C. x macrocarpa leaves and fruits are valuble source of antioxidant polyphenols with high potential for use in preparation of different natural health products.

The city of East Sarajevo is a newborn city, formed twenty years ago, after the war in Bosnia and Herzegovina, in the area of the former southern and eastern Sarajevo municipalities. Changes that oc-curred in this area were not only administrative-political.Thepopulation moved from one area to anoth-er place, and changed in number and structure, which has resulted in significant changes in land use and land cover types. The aim of the paper is to analyze the types of land cover in the area of East Sarajevo using methods based on remote sensing, in order to find out the degree of these spatial changes in the period from 2000-2012, and also to define spatial development trends. Within the European project of remote research of land cover types and forms of land use, namedCO-RINE Land Cover (CLC),spacious facilities were identified from middle and large scale spatial resolution, with 5 first-level classes, 15 subclasses, and 44 subclasses of the third level of cover. Analyzing the area of East Sarajevo there are identified 3 of the first-class level, 10 second-class, and 16 third-class level types. Geodataare related to three observation periods: 2000, 2006, and 2012, comparing the situation at the beginning of the period with the situation after 12 years.

In this paper are investigated microstructural, phase, physical and mechanical properties of mullite ceramics obtained from clay and Bayer electrofilter fines. Clay and alumina were mixed in such ratio that provides the amount of Al2O3 and SiO2 corresponding composition of mullite. One mixture was manually mixed and other was milled three hours in ceramic mill. After isostatic molding and heat treating at 1580°C and 1635°C XRD analysis revealed approximately 60% of mullite and 40% of corundum in first mixture and in second mixture 70% of mullite and 30% of corundum. Two types of mullite were observed in SEM micrographs beside corundum grains and glassy phase. The results of investigation indicate that preparation of mullite ceramics from these raw materials is possible, if clay and alumina are well homogenized and milled before molding.
