AB  - In order to further define the potential use of FTIR-ATR spectroscopy, as a non-destructive and reliable technique, for the analysis of the characteristics of post stamps, certified originals of the Principality of Serbia stamps (“Prince Michael issues”) issued in 1866 and 1868 as well as their forgeries were ana­lyzed. Spectra enabling the comparison of the paper, dye and glue of stamps of so-called “Vienna issues”, having denominations of 10 (orange-yellow), 20 (pink) and 40 para (blue) and “Belgrade issues” (1 para-green and 2 para-reddish brown), as well as 24 expert-certified forgeries, were taken. It was shown that the applied technology was, in most of the cases, a fast and suitable technique for establishing clear differences between the spectral characteristics of the paper and dye used for the original stamps, and forgeries that were most probably made decades after the printing of the genuine stamps. The differences between print­ings of the same issues of the genuine stamps were also elaborated. It is pro­posed, for the first time in philatelic history, the possibility that “Vienna issues” stamps may have been printed on two different papers, and, having in mind the technology of printing in the 19th century, potentially, not even at the same time or in the same printing house.

AB  - Poslednjih decenija mikroplastika je prepoznata kao jedan od glavnih zagađivača životne sredine. 
Nastaje kao posledica postepene degradacije/fragmentacije većih čestica plastike usled izloženosti 
različitim faktorima životne sredine kao što su UV zračenje, vetar, vodene struje, mikroorganzmi, 
itd. Jedan od najvećih izazova u rešavanju problema mikroplastike jesu metode za njenu detekciju i 
identifikaciju. Zbog raznovrsnosti mikroplastike, postoji potreba za poboljšanjem postojećih i/ili 
razvojem novih metoda kako bi se ustanovila najpouzdanija metoda za analizu mikroplastike iz 
različitih uzoraka. Cilj ovog rada bio je utvrđivanje polaznih osnova za razvoj efikasne metoda za 
detekciju i identifikaciju vrste mikroplastike koja se može naći u sedimentima međunarodnih reka 
Srbije. Iz uzoraka sedimenata reka najpre je uklonjena organska materija primenom Fentonovog 
reagnesa, nakon čega je urađeno razdvanjanje čestica mikroplastike na osnovu gustine. Supernatanti 
su izdvojeni i filtrirani, a dobijeni filtrati korišćeni za detekciju čestica mikroplastike primenom 
optičke mikroskopije. Sa ciljem utvrđivanja strukture, detektovane čestice su dalje ispitane 
primenom energetsko-disperzione spektroskopije i infracrvene spektroskopije sa Furijeovom 
transformacijom (FTIR).
AB  - Microplastics have been recognized as one of the main polluters of the environment in recent decades. It is formed as a result of gradual degradation/fragmentation of larger plastic particles due to exposure to the different environmental factors such as UV radiation, wind, water currents, microorganisms, etc. One of the biggest challenges in solving the problem of microplastics is the method for their detection and identification. Due to the diversity of microplastics, there is a need to improve existing and/or develop new methods to determine the most reliable method for the analysis of microplastics from different samples. This study was aimed to set the ground for development of efficient method for detection and identification of the microplastics from the sediments of international rivers in Serbia. The sediment samples were firstly treated with Fenton’s reagent to remove the organic matter, after which the density separation of microplastics has been performed. The collected supernatants were filtered and used for detection of the microplastics applying optical microscopy. The structure of the detected particles was examined by means of Energy-dispersive spectroscopy (EDS) and Fourier-transform infrared spectroscopy (FTIR).
