Purpose: Within the framework of research on metal and metalloid presence, as a possible consequence of the war, the areas in Eastern Croatia where agricultural activity reestablished biomonitoring (serum, hair, urine) of the local population and environmental monitoring through samples of soil, water and edible wild plants was conducted and samples of cabbage, an indicator for heavy metals and metalloids in the environment, were collected. Aim: The hypothesis of the study is that in areas of Eastern Croatian exposed to combat operations, such as the environment and population, the presence of increased concentrations of metals and metalloids is associated with war activities in relation to the areas that were spared from war. The goal was to determine whether there are differences in the concentrations of metals and metalloids comparing locations of high intensity combat action (HICA) with locations of low intensity combat action (LICA). Besides this, the attempt was to determine the possible interconnection of contamination with metals in the soil and in humans, and whether there was a coincidence in terms of potential "hot spots", places significantly loaded with metals. Materials and Methods: A total of 14 sites included 14 samples of cabbage, where 12 samples from locations of high intensity combat action (HICA) and two (2) samples from locations of low intensity combat action (LICA). The concentrations of 20 metals and metalloids (Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Ni, Pb, Sb, Si, Sr, In, V, and Zn), which are used for military purposes, were determined by inductive procedure of restrained plasma mass spectrometry ICP-MS. Results: The concentration of metals covered by Regulations (As, Cd, Hg and Pb) were within the MRL on all locations, while in the other investigated elements there was no difference between HICA and LICA (p = 0.78; Mann-Whitney U test). The concentration of metals and metalloids in cabbage was not significantly correlated with the concentration in the soil samples, except in the case of Cd, where the negative correlation (Pearson coefficient soil/cabbage =-0.57; p = 0.031; p < 0.05) was observed. The principal component analysis (PCA) determined a compact central cluster, and two clusters on locations Dopsin and Dalj, where the concentration of all the elements, except for Hg, was higher. Conclusions: Even cabbage, as an indicator of environmental contamination with metals, indicates that after the war the total load of metal in Eastern Croatia is not high. However, the cabbage also confirmed the locality of Dalj as a "hot spot", accordingly to previously established positive correlations of Al, Fe, Mg and Ni in hair, soil and dandelion, and B, Cu, Si, Sr and Zn correlations in serum, urine and water in that same location, indicating a possible common source and mechanism of transferring metals. © 2017, Opca Bolnica Zadar.

The aim of this study was to determine content of nutrients and carnosine concentration in thighs (dark meat) of chickens of the Ross 308 provenance with respect to chicken gender. Amount of carnosine is determined by the HPLC device. Thigh muscle tissue of female and male chickens contains 339.28±68.17 μg/g and 319.29±65.47 μg/g of carnosine (P>0.05), respectively. Live end weights of chickens are also shown, with average male chickens weights of 2377 g and female chickens 2104 g (P≤0.01). Average carcass weights of male and female chickens were 1600 g and 1443 g, respectively (P≤0.01). Portions of basic parts in the carcass and the composition of nutrients (lipids, proteins, moisture and collagen) in thigh muscles (P>0.05) are also shown. The obtained research results are explained in the context of other relevant studies on a similar topic.

Wastewaters from industries which produce or use colours present a significant ecological problem due to their intensive colouration and consistence of recalcitrant organic compounds. Those wastewaters can not be discharged into the environment without prior adequate treatment. Application of processes for removal of dyes from effluents is based mostly on physiochemical methods. Such methods are effective only if the effluent volume is small, often very costly and, although the dyes are removed, accumulation of concentrated toxic sludge creates a significant secondary disposal problem. There is a need to find low cost and environmentally friendly alternative treatment processes that are effective in removing dyes from large volumes of industrial effluents such as biological systems.

This article describes the history and development of the Croatian nomenclature of organic chemistry from the publication of the first translation of international nomenclature recommendations to the present age. In the Introduction, trivial, common, systematic (rational), and semisystematic names are defined, and the etymology and meaning of terms nomenclature and terminology are clarified. At the beginning of the central part of this article, attention is focused on the need to create our national nomenclature. The very first such project, initiated by the Croatian Chemical Society (CCS), was the translation of the Geneva (1892) and Liège rules (1930) published in 1954. In 1979 comprehensive general IUPAC rules appeared, and the Croatian Society of Chemical Engineers (CSCE) in two volumes printed the Croatian edition of this important document, known as the Blue Book, in 1985 and 1988. A Guide to IUPAC Nomenclature of Organic Compounds (1993) expanded the main principles and rules from the Blue Book, and introduced a higher degree of organic nomenclature systematization. The Croatian translation of the Guide was published in 2002. In the last six decades, almost fifty translations of international rules have been issued, and almost all of them represented the official recommendations of the CCS/CSCE. Finally, the nomenclature in the translations of five comprehensive textbooks for organic chemistry is analysed. In conclusion, readers are informed that the Croatian version of IUPAC rules is applied in our secondary school and university education, in Croatian encyclopaedism and mass media, as well.
