Halide removal from aqueous solution by novel silver-polymeric materials

The objective of this study was to analyze the behavior of a new material, silver-doped polymeric cloth (Ag-cloth), in the removal of bromide and iodide from waters. Silver is immobilized on the cloth, guaranteeing selective adsorption of the halide ions a ...

Harmful effects of silver nanoparticles on a complex detrital model system

Ahmed Tlili, Renata Behra

The rapid proliferation of silver nanoparticles (AgNP) in industry and the environment requires realistic toxicity assessments based on approaches that consider the biological complexity of ecosystems. Here we assessed the acute toxicity of carbonate-coate ...

Nanotoxicology: 2D analysis in a 3D matrix

Anders Meibom, Louise Helene Soegaard Jensen

Engineered nanoparticles are the fastest growing nanotechnology product, and of increasing environmental concern. Examples include antimicrobial silver nanoparticles, iron oxide particles used in bulk scale for environmental remediation, and micro- and nan ...

Critical influence of chloride ions on silver ion-mediated acute toxicity of silver nanoparticles to zebrafish embryos

Kristin Schirmer, Renata Behra

The toxicity of silver nanoparticles (AgNP) to aquatic organisms, including zebrafish (Danio rerio), has been demonstrated, but differing opinions exist on the contribution of the physical properties of the particles themselves and the free dissolved silve ...

Carbon supported gold and silver: Application in the gas phase hydrogenation of m-dinitrobenzene

Lioubov Kiwi, Fernando Cardenas Lizana

We have studied the gas phase continuous hydrogenation of m-dinitrobenzene (m-DNB) over acid treated activated carbon (AC) supported Au and Ag prepared by deposition-precipitation. Temperature programmed reduction of a 1%wt. metal loading generated a broad ...

Silver nanoparticle toxicity and association with the alga Euglena gracilis

Kristin Schirmer, Laura Sigg, Renata Behra, Xiaomei Li, Laetitia Bernard

The impact of silver nanoparticles (AgNPs) on aquatic algae has largely been studied with model species that possess a rigid cell wall. Here, we explored the interactions of AgNPs with Euglena gracilis, a green alga having no cell wall but a pellicle. The ...

Silver nanoparticle effects on simple stream food webs and ecosystem processes

Carmen Omayra Gil Allué

With the global nanotechnology market growing rapidly, nanomaterials are being increasingly released into aquatic environments, where they can undergo modifications and sedimentation, which will put benthic organisms at risk. Of particular interest is the ...

Silver Nanoparticle Effects on Stream Periphyton During Short-Term Exposures

Kristin Schirmer, Ahmed Tlili, Renata Behra

Silver nanoparticles (AgNP) are increasingly used as antimicrobials in consumer products. Subsequently released into aquatic environments, they are likely to come in contact with microbial communities like periphyton, which plays a key role as a primary pr ...

Linking toxicity and adaptive responses across the transcriptome, proteome, and phenotype of Chlamydomonas reinhardtii exposed to silver

Kristin Schirmer, Laura Sigg, Renata Behra

Understanding mechanistic and cellular events underlying a toxicological outcome allows the prediction of impact of environmental stressors to organisms living in different habitats. A systems-based approach aids in characterizing molecular events, and the ...

Release and environmental impact of silver nanoparticles and conventional organic biocides from coated wooden facades

Andrea Ulrich

This study represents for the first time a comprehensive assessment of functionality and environmental impacts of metallic silver nanoparticles (Ag-NP) compared to conventional organic biocides. Four different transparent, hydrophobic coatings of wooden ou ...
