AB  - The contamination of the water bodies by diesel oil (DO) and its water-soluble fraction (WSF) represents one of the most challenging tasks in the management of polluted water streams. This paper contains data related to the synthesis and characteristics of the plum stone biochar material (PmS-B), which was made from waste plum stones (PmS), along with its possible application in the sorption of the WSF of DO from contaminated water. Techniques applied in sample characterisation and comparisons were: Elemental Organic Analysis (EOA), Scanning Electron Microscopy−Energy Dispersive X-ray Spectroscopy (SEM-EDX), Fourier Transform Infrared Spectroscopy (FTIR), pH (pHsus) and point of zero charge (pHpzc). In order to increase the overall efficiency of the removal process, sorption and bioremediation were subsequently combined. Firstly, PmS-B was used as a sorbent of WSF, and then the remaining solution was additionally treated with a specific consortium of microorganisms. After the first treatment phase, the initial concentration of diesel WSF was reduced by more than 90%, where most of the aromatic components of DO were removed by sorption. The sorption equilibrium results were best fitted by the Sips isotherm model, where the maximum sorption capacity was found to be 40.72 mg/g. The rest of the hydrocarbon components that remained in the solution were further subjected to the biodegradation process by a consortium of microorganisms. Microbial degradation lasted 19 days and reduced the total diesel WSF concentration to 0.46 mg/L. In order to confirm the non-toxicity of the water sample after this two-stage treatment, eco-toxicity tests based on a microbial biosensor (Aliivibrio fischeri) were applied, confirming the high efficiency of the proposed method.

AB  - Infant nutrition is essential for their growth and development. This research aims to determine the total antioxidant capacity of the infant food for preterm infants and indicate adequate methods for testing the quality and biological value of milk and infant food. The total antioxidant capacity (TAC) was determined in human milk and an infant formula for premature infants. The determination of the total antioxidant capacity was made using cyclic and differential pulse voltammetry, potentiometry and electron paramagnetic resonance spectroscopy. The results of three comparative electrochemical methods indicate that human milk has a higher antioxidant potential compared to infant formula, which contributes to better physiological development of the child. Fenton-based electron paramagnetic resonance spectroscopy method provides additional insight into TAC analysis, whereby a carbon-centered radical and an ascorbyl radical are formed in infant food. All methods can be used to determine TAC, since the results obtained individually with each method follow the same trend.
