Transport of hydrophobic pollutants in rivers such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and heavy metals is often facilitated by suspended sediment particles, which are typically mobilized during high discharge events. Suspended sediments thus represent a means transport for particle related within river reaches may suitable proxy average pollutant concentrations estimation reach or catchment. In this study, multiple discharge/turbidity events were...
The dissolution of upconverting AYF4:Yb,Tm (A = Na or K) nanoparticles (UCNPs) in aqueous media was systematically studied. UCNPs with a cubic structure and sizes between 10 33 nm were synthesized solvothermally ethylene glycol at 200 °C. both compositions showed an upconversion fluorescence emission characteristic Tm(3+). effects the A cation, particle size, temperature, pH, composition medium on evaluated. degree determined from fraction dissolved fluoride (F(-)) using potentiometry....
Titanium dioxide is a white colourant authorised as food additive E 171 in the EU, where it used range of alimentary products. As these materials may contain fraction particulates with sizes below 100 nm and current EU regulation requires specific labelling ingredient to indicate presence engineered nanomaterials there now need for standardised validated methods appropriately size quantify (nano)particles matrices. A single-particle inductively coupled plasma mass spectrometry (spICP-MS)...
There has been a growing interest in recycling and upcycling different waste streams due to concerns for environmental protection. This prompted the desire develop circular economies optimize utilization of bioresources industrial sectors. Turning agricultural forestry into high-performance materials is promising meaningful strategy creating value-added materials. Lignocellulose fibres from plants are emerging as potential candidate eco-friendly feedstock textile industry. Nonwoven fabric...
Nanoremediation procedures are usually designed so that only one contaminant or similar class of contaminants is being considered. In the present work, a holistic approach was applied towards processes which simultaneously occur after treatment real effluent water from small biological wastewater plant (SBWTP) with different nanoscale zero-valent iron (nZVI) particles. Three types nZVI particles were tested: in-house nZVI, commercially available Nanofer STAR and Nanofer25 slurry, differ in...
Low translocation but considerable accumulation of Ag in placental tissue was found perfusion studies with AgPEG and AgCOONa NPs.
River ecosystems are exposed to various stressors. Among them, elements may contribute overall pollution of riverine environments, in particular during the extreme flow events. To evaluate influence variable river conditions on mobilization potentially toxic (PTE) (Cr, Ni, Cd, Zn, Pb, As and Cu) from sediments into overlaying waters Sava River, samples were collected September 2014, extremely high water discharges 2015, under low discharge conditions. In total element concentrations...
River ecosystems are under pressure from several different stressors. Among these, inorganic pollutants contribute to multiple stressor situations and the overall degradation of ecological status aquatic environments. The main sources pollution include industrial activities, untreated effluents municipal waste waters intensive agriculture. In present study, water, suspended particulate matter (SPM) sediments Sava were studied in order assess this river system. Sampling was performed during...
The majority of the clinically approved iron oxide nanoparticles (IO NPs) used as contrast agents for magnetic resonance imaging (MRI) have been withdrawn from market either due to safety concerns or lack profits. To address this challenge, liposomes prepare IO-based T2 agents. We studied influence different phospholipids on relaxivity (r2) values magneto-liposomes (MLs) containing NPs in bilayer, where a strong correlation between bilayer fluidity and r2 is clearly shown. Embedding 5-nm IO...
In healthcare facilities, infections caused by Staphylococcus aureus (S. aureus) from textile materials are a cause for concern, and nanomaterials one of the solutions; however, their impact on safety biocompatibility with human body must not be neglected. This study aimed to develop novel multilayer coating poly(allylamine hydrochloride) (PAH) immobilized ZnO nanoparticles (ZnO NPs) make efficient antibacterial biocompatible cotton, polyester, nylon textiles. For this purpose, coated...
Loss of implant function is a common complication in orthopaedic and dental surgery. Among the primary causes failure are peri-implant infections which often result removal. This study demonstrates development new antimicrobial titanium coating with ZnO nanoparticles various sizes morphologies immobilised poly(allylamine hydrochloride) alginate multilayers, combined epitaxially grown vaterite crystals. The coated samples were characterised methods (FTIR, XRD, SEM) surface properties...
The method using enzymatic tissue treatment followed by spICP-MS is efficient for determination of mass and number concentration size distribution AgNPs in human placental tissues.
As a consequence of their widespread use, titanium dioxide nanoparticles (TiO2NPs) have been released into the environment where they can act as stressors towards biota. For assessment environmental impact these NPs it is important to quantitatively determine concentration, size distribution and dissolved Ti fraction in different water samples. In present work, new analytical approach was applied for sizing quantitative determination TiO2NPs (anatase rutile) aqueous samples by use single...
The presence of nanomaterials in the environment has caught attention scientific because uncertainties their fate, mobility and potential toxic effects. However, few studies have determined experimentally concentration levels aquatic systems up to date, which complicates development an adequate risk assessment. In present study, occurrence ten fullerenes been assessed Sava River (Southeastern Europe): 27 freshwater samples 12 sediment from sampling points analysed during two campaigns. C60...
In this study we have performed a comprehensive genotoxicological survey along the 900 rkm of Sava River. total, 12 sites were chosen in compliance with goals GLOBAQUA project dealing effects multiple stressors on biodiversity and functioning aquatic ecosystems. The genotoxic potential was assessed using complex battery bioassays prokaryotes eukaryotes (freshwater fish).

Titanium dioxide nanoparticles (TiO2NPs) are widely produced and used NPs in different applications. To evaluate the risk from anthropogenic TiO2NPs, more information is needed on their occurrence environment. For first time, this study reports levels of TiO2NPs waters sediments at selected sampling sites along Sava River using inductively coupled plasma mass spectrometry single particle mode (spICP-MS).
