AB  - The aim of this study was to investigate the quinoa fruit and seed microstructure, as well as to determine the qualitative composition of quinoa whole seed spatial localisation of food reserves in cultivars Puno and Titicaca using two complementary spectroscopic techniques (Fourier Transform infrared and Raman). The analyses of the seeds also included measurements of the crude proteins and starch contents. The experiment was carried out during the 2016 growing season in rain-fed conditions in the north of Serbia. The analysis of the scores of the principal components based on the Raman spectra revealed two groups in both seed parts (cotyledons and perisperm). The analysis of the loadings highlighted the spectrum region that contributed to the differentiation, e.g. the band at 472 cm(-1) was related to the amylopectin content in the perisperm region. As for the cotyledons, the spectral range from 1100 to 1650 cm(-1) was responsible for genotype differences and it included both the most important bands derived from Amide I, II and quinoa protein with globoid crystals composed of phytin. IR analysis, similar to the analyses of the crude proteins and starch contents in the seeds, failed to reveal any differences in biochemical composition between two analyzed genotypes.

AB  - The paper addresses the issue of health risk associated with the presence of chrysotile in the soil type ranker formed on massive serpentines occurring in the area of Bubanj Potok, a settlement located in the southern Belgrade environs, Serbia. Characterization of the ranker soil was conducted by scanning electron microscopy, X-ray diffraction, micro-Raman spectroscopy and transmission 57Fe Mössbauer spectroscopy. Scanning electron microscopy figures showed regular shaped smectite (montmorillonite) particles, aggregates of chlorite, and elongated sheets of serpentines minerals antigorite. X-ray diffraction analysis confirmed the presence of detrital mineral quartz polymorph as well as minor amounts of other mineral species. Micro-Raman spectroscopy identified the presence of dominant minerals, such as montmorillonite, kaolinite, muscovite, gypsum, calcite, albite, amphiboles (hornblende/kaersutite) and orthoclase. Important polymorph silica modifications of quartz, olivine (forsterite), pyroxene (enstatite/ferrosilite, diopside/hedenbergite), and serpentine (antigorite/lizardite/chrysotile) were identified.
AB  - Rad se bavi pitanjem zdravstvenog rizika povezanog sa prisustvom hrizotila u rankeru (tip zemljišta) formiranom na masivnom serpentinitu u oblasti Bubanj Potoka, naselju koje se nalazi u južnoj okolini Beograda. Karakterizacija rankera je izvršena skenirajućom elektronskom mikroskopijom, rendgenskom difrakcijom praha, mikro-Raman spektroskopijom i transmisionom 57Fe Mesbauer spektroskopijom. Slike dobijene skenirajućim elektronskim mikroskopom pokazuju čestice smektita regularnog oblika montmorionita, agregata hlorita i izdužene listove serpentinskog minerala antigorita. Rendgenska difrakciona analiza potvrdila je prisustvo detrital minerala kvarcnog polimorfa kao i manje količine drugih mineralnih vrsta. Mikro-Raman spektroskopija identifikovala je prisustvo dominantnih minerala, kao što su montmorionit i kaolinit, muskovit, gips, kalcit, albit, amfibol (kaersutit/hornblenda) i ortoklas. Važni polimorfi silika modifikacije kvarca, olivina (forsterit), piroksena (enstatit, ferosilit, hedenbergit, diopsid), i serpentina (antigorit, lizardit, hrizotil) su bili identifikovani.
