AB  - Polymethyl methacrylate (PMMA) is a polymer material widely used in dental applications due to its excellent biocompatibility, stable physicochemical properties, easy manipulation, and low cost. The combination of biocompatible polymers and ceramics has great potential for the development of materials in the dental industry with improved mechanical properties. The addition of Al2O3 nanoparticles to PMMA can significantly improve its compressive and flexural strengths and wear resistance. Since this material is used in dental applications, it requires a high degree of product sterility. This can easily be achieved with gamma radiation treatment. Gamma radiation not only ensures the sterility of the product but can also affects changes in numerous material properties.The aim of this paper is to determine the influence of different doses of gamma radiation on the microbio-logical purity and changes in the mechanical and thermal properties of the PMMA/Al2O3 composite as well as the microstructural and color changes. It was found that the dose of radiation of 25 kGy is sufficient for complete sterilization of the product. This radiation dose improves the mechanical properties of the material and thermal stability. On the other hand, the dose of 25 kGy does not affect the morphology of the exposed sample and has small effect on the color change.

AB  - Anacamptis morio occurs on a wide range of habitats showing distinct tolerance to heterogeneous
edaphic conditions. Assessment of Li, B, Ba, and Sr phytoavailability in the soils of western
Serbia, and metal(oid) uptake by A. morio provided new information on less studied elements and
revealed their relatively high mobility in the soil-orchid system. Although previous studies have
found that A. morio prefers neutral and calcareous soils, our study shows that it also inhabits ultramafic
and siliceous sites characterized by pronounced differences in soil chemical properties. BCR
sequential extraction identified up to 60% of Li and more than 80% of Ba and Sr content as potentially
phytoavailable. The total element analyses using ICP-OES showed that B, Ba and Sr predominantly
accumulated in the roots, but did not exceed thresholds considered potentially phytotoxic.
It revealed the exclusion strategy of A. morio which enables it to tolerate differences in elemental
composition of contrasting bedrock types. The highest Li concentrations were detected in leaves,
pointing to significant Li mobility within the plant. The contents of Li and Ca were highly positively
correlated, which may result from Li physicochemical properties that are similar to those of alkali
metals, allowing it to share the same transport carriers. Thus, Li could be easily transported to the
aboveground plant parts and accumulated mainly in the organs with the highest Ca content,
which was confirmed in this study. Bioconcentration factors >1 were detected only for B and Sr in
all plants analyzed, irrespective of the bedrock type.

AB  - In this study concentration of toxic elements As, Cd, and Pb was determined in
different soil types and belonging orchid species Anacamptis morio vital parts, in order to
examine accumulation patterns and provide new insights about potential use of this
orchidin bioremediation technology. The soils developed on limestone, serpentine, and the
chert were subjected to the BCR sequential extraction. Samples of orchid root and tuber,
as underground parts, and stem, leaves, and inflorescence, as above-ground organs, were
also analyzed for content of As, Cd and Pb. During this research, it was observed that metal
content in soil is directly proportional to its content in the plant, more specifically in roots,
which suggest that A. morio can potentially be used in phytostabilization of contaminated
sites. Values for BCF factors showed Cd immobilization in roots regardless of the soil type.
Certain level of arsenic was trasfered from root to leaves indicating potential for
accumulation of this element into aboveground organs. Assessment of the
phytoremediation potential of this orchid or another plant species from diverse
environments is important as it provides information about possibility of their future
application in environmental remediation programs.
