AB  - The analysis of isotope ratios of lead in the mushrooms and soil, where they were grown, assisted with a principal component analysis, offered a new perspective for understanding possible chemical environment in a real setup of those compartments. The content of lead and its isotope compositions were determined in soil samples and mushroom Macrolepiota procera from unpolluted area of Mountain Goč, Serbia. Sequential extraction procedure based on the Commission of the European Community Bureau of Reference (BCR) was applied on soil samples in order to determine the distribution of lead in the labile and un-labile fractions of the soil. Caps and stipes of mushrooms were subjected to microwave acid-assisted digestion prior to measurements by inductively coupled plasma quadrupole mass spectrometer for determination of lead content and lead isotope ratios. Information about the chemical fractionation of Pb in soil, Pb isotopic data from soil fractions and fruiting bodies allowed a more detailed insight on the uptake mechanisms. Lead was predominantly associated with reducible fraction (~ 60%). Only its small portion (∼ 1%) was present in the exchangeable and acid-extractable fractions suggesting the low mobility of Pb. Lead isotope analysis revealed the presence of anthropogenic lead in the surface soil. Significant lower 206Pb/207Pb compared with other fractions was found in exchangeable and acid-soluble fraction (1.331 ± 0.010), which corresponds to the isotope ratio of European gasoline. The highest 206Pb/207Pb ratio was observed in reducible fraction (1.162 ± 0.007), while in oxidizable and residual fraction, those values were similar (1.159 ± 0.006 and 1.159 ± 0.004, respectively). Distinction of exchangeable and acid-extractable fractions from others was also confirmed, for the first time, by principal component analysis. The analysis of four isotope ratios (206Pb/207Pb, 208Pb/206Pb, 206Pb/204Pb, and 207Pb/204Pb) indicated that the analyzed M. procera accumulates lead from the first two fractions of topsoil layers.

AB  - In this paper, agricultural waste (corn stover and wheat straw) was used for isolation of microcrystalline cellulose (MCC). Lignocellulosic biomass is widely available and applying smart technologies to valorise it will have a double benefit through environmental protection and achieving high-performance materials for targeted applications. The obtained MCC showed excellent features in terms of purity, physical-chemical properties and safety, as well. The methods applied for characterizing the materials were as follows: FT-IR, SEM, ICP-AAE and IC. Then, tablets were made by the compression method, using the isolated and purified MCC, as well as its commercially available counterpart. Excellent technological characteristics were confirmed by testing material compaction, compactibility, compressibility and drug release. This was one of the first tests in which Gamlen Tableting D was applied, especially in the case of using biomass, in the first phase, with prospects of application at a large scale, particularly, in the pharmaceutical industry.
