Caddisfly emergence is substantially affected by the combined exposure of titanium dioxide nanoparticles, natural organic matter and UV irradiation Open
Nanoparticles serve various industrial and domestic purposes which is reflected in their steadily increasing production and ultimate release into the environment. Titanium dioxide nanoparticles pose due to their high production volume and …

Fate and effects of silver nanoparticles at the aquatic-terrestrial interface: A floodplain mesocosm experiment Open
The production volume of engineered inorganic nanoparticles (EINP) successively increased over the last years. Once released into the natural environment, these particles may change their size and surface properties in interaction with oth…

Quantity and quality of natural organic matter influence the ecotoxicity of titanium dioxide nanoparticles Open
Nanoparticles’ fate is amongst other parameters determined by the quantity and quality of natural organic matter (NOM). Consequently, the ecotoxicity of nanoparticles is modified, while only little information is available on the NOM chara…

Impact of chemical composition of ecotoxicological test media on the stability and aggregation status of silver nanoparticles Open
Aggregation status of Ag NPs in ecotoxicological test media is controlled by the Ca2+/Mg2+ ratio, presence of Cl− and Br− and NOM quality.

Aging of TiO2 Nanoparticles Transiently Increases Their Toxicity to the Pelagic Microcrustacean Daphnia magna Open
During their aquatic life cycle, nanoparticles are subject to environmentally driven surface modifications (e.g. agglomeration or coating) associated with aging. Although the ecotoxicological potential of nanoparticles might be affected by…

Inorganic fungicides as routinely applied in organic and conventional agriculture can increase palatability but reduce microbial decomposition of leaf litter Open
Summary The application of fungicides is considered an indispensable measure to secure crop production. These substances, however, may unintentionally enter surface waters via run‐off, potentially affecting the microbial community. To asse…
