In the present paper, we study mechanism of antibacterial activity glutathione (GSH) coated silver nanoparticles (Ag NPs) on model Gram negative and positive bacterial strains. Interference in cell replication is observed for both cellular strains when exposed to GSH stabilized colloidal solution, microbicidal was studied Ag NPs are (i) dispersed suspensions or (ii) grafted thiol-functionalized glass surfaces. The obtained results confirm that effect capped (GSH Escherichia coli more intense...
In the present work, we describe a simple procedure to produce biomimetically coated silver nanoparticles (Ag NPs), based on postfunctionalization and purification of colloidal stabilized by citrate. Two biological capping agents have been used (cysteine Cys glutathione GSH). The composition capped colloids has ascertained different techniques antibacterial tests GSH-capped Ag NPs conducted under physiological conditions, obtaining values Minimum Inhibitory Concentration (MIC) 180 15 μg/mL...
The burrowing and feeding activities of benthic organisms can alter metal speciation in sediments affect an organisms' exposure to metals. Recently, the performance situ technique diffusive gradients thin films (DGT) for predicting bioavailability has been investigated response increasing demand considering contaminant sediment quality assessments. In this study, we test ability DGT clean contaminated that are being subjected varying degrees disturbance: low bioturbation (bivalve Tellina...
Many sediment quality assessment frameworks incorporate contaminant bioavailability as a critical factor regulating toxicity in aquatic ecosystems. However, current approaches do not always adequately predict metal to organisms living the oxidized surface layers. The deployment of diffusive gradients thin films (DGT) probes sediments allows labile metals present pore waters and weakly bound particulate phase be assessed time-integrated manner situ. In this study, relationships between...
Water quality monitoring programs yield a wealth of data. It is often unclear why certain substance occurs in higher concentrations at location or time. In this study, substances were considered clusters with co-varying rather than isolation. A total 196 19 sites the rivers Rhine and Meuse identified. nine found repeatedly similar composition different sites. Several environmental conditions properties could be linked to clusters. addition, overlap reference lists was determined. These group...
Atmospheric deposition is an important pathway for PFAS to enter soil, surface water and groundwater, but their persistence mobility complicate source identification. Understanding these pathways crucial safeguarding drinking production, as poses risks human health. This study investigated atmospheric in two production locations located 135 km apart, highlighting its potential impact the contaminating water, groundwater. Aerosol samples were collected along with meteorological data at both...
Water quality monitoring programs produce extensive data, yet the drivers of temporal and spatial variations in substance concentrations often remain unclear. Our studies cluster substances with co-varying across 19 sites Rhine Meuse rivers, identifying 196 clusters. Nine recurring clusters, consistent compositions sites, were linked to environmental conditions properties. Overlap reference lists, categorizing by source or usage, highlighted similar impacts on both rivers. Some could not be...
The use of diffusive gradients in thin films (DGT) for predicting metal bioavailability was investigated by exposing the bivalve Tellina deltoidalis to an identical series metal-contaminated sediments deployed simultaneously field and laboratory. To understand differences exposure occurring between laboratory- field-based bioassays, we changes fluxes DGT probes concentrations partitioning porewaters overlying waters. DGT-metal (Cu, Pb, Zn) were lower waters most bioassays compared...
Abstract The issue of microplastic (MP) litter in the aquatic environment and its capability accumulating and/or releasing pollutants has been brought to light recent years. Biodegradable plastics have proposed as one different solutions decrease environmental input discarded plastics; however, their ability accumulate release once marine not assessed yet. In this study, we compare accumulation a wide range compounds by biodegradable (polyhydroxyalkanoates (PHA) polybutylene succinate (PBS))...
Xanthates, derivatives of xanthic acid, are widely utilized across industries such as agrochemicals, rubber processing, pharmaceuticals, metallurgical, paper and mining to help separate metals from ore. Despite their prevalent use, many registered xanthates lack comprehensive information on potential risks human health the environment. The sector, a significant consumer xanthates, drives demand. However, emissions into environment remain poorly understood, especially concerning water...
Background: Persistent and mobile organic compounds (PMOC) are of great concern for water quality human health. The recent improvement availability high-resolution mass spectrometry in combination with liquid chromatography have widely expanded the potential analytical workflows their detection quantitation water. Given high polarity, some PMOC requires alternative techniques to reversed-phase chromatography, such as hydrophilic interaction (HILIC) supercritical fluid (SFC). Unified (UC), an...
