AB  - Abstract:
Introduction. The SOS/umuC assay is used for assessment of water genotoxicity. Salmonella typhimurium TA1535/pSK1002 is used in this test, but the results can be extrapolated on higher eukaryotic organisms with the introduction of enzymatic S9 fraction in experimental procedure. The test is standardised for the determination of the genotoxic potential of water and wastewater (ISO/DIS 13829, 2000). Aim. Sensitivity of the assay was challenged by using parallel in situ and in vitro approach in evaluation of the genotoxic potential in the basins of significant tributaries of the Danube River: the Sava River and the Velika Morava River. Materials and methods. Within in vitro testing, native water samples were analysed by SOS/umuC test. DNA damage in situ was assessed in bleak (Alburnus alburnus) erythrocytes by the comet and micronucleus assays. The concentration of heavy metals in fish tissue and the data of the physico-chemical parameters measured in water were used as a measure of the pollution pressure at the sites. Results. Results showed that applied in vitro tests with native water samples are less sensitive in comparison with in situ tests. None of 20 investigated samples showed genotoxic potential in SOS/umuC assay while in situ analyses indicated variation of genotoxic potential among the investigated sites. Conclusions. The results of our study point towards low sensitivity of the SOS/umuC test when processing un-concentrated (native) water samples; the results of in vitro tests should be taken with precaution when making predictions on the status of the ecosystem.

AB  - Barium strontium titanate powder Ba0.8Sr0.2TiO3 (BST) has been obtained by
hydrothermal treatment of precursor solution containing titanium citrate, previously
prepared by complex polymerization method, and barium and strontium acetates.
The powders were calcined at 700 °C, pressed into pellets and further sintered at
1280 °C for a various sintering times (from 1 to 32 h), and structural parameters,
phase composition, dielectric and ferroelectric properties were investigated. Rietveld
refinement analysis of BST ceramics showed that predominant phase was tetragonal
BST with monoclinic Ba6Ti17O40 (B6T17) as a secondary phase. Phase contents
determined by Rietveld refinement match well with the results of energy dispersive
X-ray analysis and ICP analysis. SEM micrographs of sintered samples revealed the
abnormal grain growth where elongated twinned grains of BST grow in a matrix of
smaller B6T17 grains. Dielectric and ferroelectric properties of BST ceramics have
been correlated with density of sintered compacts, phase composition, structural
parameters and microstructure. The sample sintered for 16 h showed the highest
density (93% ρt), as well as the highest value of dielectric constant (~2300) and
remanent polarization – Pr (2 μC/cm2) among investigated samples.
