Summary: A new magnetic amino-functionalized polymeric sorbent was synthesized and used for the separation of Cr(VI) oxyanions from aqueous solutions. The sorption process was found to be controlled by both intraparticle diffusion and liquid film diffusion. The equilibrium results showed that the sorption process is best described by the Freundlich model, with a maximum sorption capacity of 64 mg/g. Quantum chemical modeling revealed that the sorption sites on the sorbent surface are fragments with diethylenetriamine and aminopropyl silane groups. XPS spectra demonstrated that the chromium bound to the sorbent in the form of Cr(III), indicating its conversion to a less harmful form on the surface of the sorbent.

Summary: Cellulose is a common polymer in domestic wastewater that can be reused in various ways after separation. However, the impact of the absence of cellulose on a biological process has not been studied extensively. This research simulated anoxic treatment of wastewater with and without cellulose for three months and found no significant difference in the chemical and physico-chemical parameters. These results are important in showing that cellulose separation from domestic wastewater for recovery/reuse purposes does not affect the effectiveness of anoxic treatments on pollutants removal.

Summary: The concentrations of cadmium (Cd), lead (Pb), and nickel (Ni) in regular and slim cigarette brands in the Serbian market were analyzed, and their human health risks were evaluated. The metal concentrations varied between cigarette brands, with higher levels in regular cigarettes but higher concentrations per cigarette tobacco mass in slim cigarettes. Counterfeit cigarettes had slightly higher metal concentrations than authentic brands. Lead was found to be the most abundant toxic metal, followed by nickel and cadmium. The calculated cumulative hazard index (HI) and incremental lifetime cancer risk (ILCR) indicated a low noncarcinogenic risk and a low but not negligible carcinogenic risk from Cd, Pb, and Ni. The probabilistic and deterministic approaches yielded similar results for the mean HI and ILCR values. A Monte Carlo simulation was used to reduce the uncertainty of health risk estimation, and sensitivity analysis showed that cigarette mass was the most influential factor, followed by Cd content.

Summary: Despite the practical approach for characterizing the environmental risk of potentially toxic elements (PTEs) from steel production, the analysis of bioavailable PTEs concentrations in soil is often overlooked in managing polluted sites. This study investigated the DTPA-extractable forms of PTEs in soils near a major Serbian steel production plant, revealing significant variability and suggesting an anthropogenic origin. Self-organizing maps (SOMs), principal component analysis (PCA), and positive matrix factorization (PMF) further confirmed the common origin and provided a basis for comprehensive assessment and soil remediation.

Summary: Public parks and open playgrounds play a critical role in urban environment by providing relaxation and recreation for city residents. A study in Krusevac, Serbia, analyzed soil samples from 18 parks and playgrounds to determine the occurrence, levels, and sources of 16 priority polycyclic aromatic hydrocarbons (PAHs) and assess human health risk. The concentrations of PAHs in the soil were found to be below national limits and lower than reported values in other cities. Traffic emissions and combustion of coal, firewood, and natural gas were identified as the main sources of PAHs in the analyzed soil. Risk assessment showed no significant health risks associated with exposure to PAHs for adults and children using these recreational areas.
