Biological surface coating and molting inhibition as mechanisms of TiO2 nanoparticle toxicity in Daphnia magna.
André Dabrunz,Lars Duester,Carsten Prasse,Frank Seitz,Ricki R. Rosenfeldt,Carsten Schilde,Gabriele E. Schaumann,Ralf Schulz +7 more
TL;DR: It is found that suspensions of nanosized (∼100 nm initial mean diameter) titanium dioxide (nTiO2) led to toxicity in Daphnia magna at nominal concentrations and predicted levels as low as 0.24 mg/L (96-h EC50) based on measured concentrations and hypothesized a mechanistic chain of events for n TiO2 toxicity inD. magna that involves the coating of the organism surface with nTiO 2 combined with a molting disruption
Fungal composition on leaves explains pollutant-mediated indirect effects on amphipod feeding.
Mirco Bundschuh,Jochen P. Zubrod,Sujitra Kosol,Lorraine Maltby,Christoph Stang,Lars Duester,Ralf Schulz +6 more
TL;DR: Effects of a fungicide on the conditioning process of leaf material by means of food-choice experiments using Gammarus fossarum seems to be a suitable indicator for alterations in leaf associated microbial communities, especially fungal species composition, caused by chemical stressors.

Translocation of Sb and Ti in an undisturbed floodplain soil after application of Sb2O3 and TiO2 nanoparticles to the surface.
TL;DR: The results show that metal(loid)s from metal oxide NPs are transported in the soil pore water and, hence, have the potential to act as the source of contamination of deeper soil layers after soil surface contamination.

A robust, particle size independent, method for quantifying metal(loid oxide) nanoparticles and their agglomerates in complex environmental matrices by electrothermal vaporisation coupled to ICP-MS
Lars Duester,Denis Rakcheev,Julia V. Bayer,Priya Mary Abraham,André Dabrunz,Ralf Schulz,Gabriele E. Schaumann +6 more
TL;DR: In this paper, the authors presented a method/concept for the multi-element quantification of analytes from ENPs in complex matrices with different degrees of complexity by graphite furnace electrothermal vaporization coupled to inductively coupled plasma quadrupole mass spectrometry equipped with collision/reaction cell (GF-ETV-ICP-QMS).
