Exposure protocol for ecotoxicity testing of microplastics and nanoplastics

Fazel Abdolahpur Monikh; Anders Baun; Nanna B. Hartmann; Raine Kortet; Jarkko Akkanen; Jae-Seong Lee; Huahong Shi; Elma Lahive; Emilia Uurasjärvi; Nathalie Tufenkji; Korinna Altmann; Yosri Wiesner; Hans-Peter Grossart; Willie Peijnenburg; Jussi V. K. Kukkonen

Despite the increasing concern about the harmful effects of micro- and nanoplastics (MNPs), so far, there exist no harmonised guidelines for testing the ecotoxicity of MNPs. An international research team with IGB has now developed protocols to assess the toxicity of these substances in soil and aquatic ecosystems.

Time Series of Electrical Conductivity Fluctuations Give Insights Into Long-Term Solute Transport Dynamics of an Urban Stream

Anna Jaeger; Jonas L. Schaper; Paul Romeijn; Andrea Betterle; Malte Posselt; Stefan Krause; Jörg Lewandowski; Joakim Riml

A solute transport model was applied to diurnal electrical conductivity fluctuations in a river to obtain long-term time series of transport metrics. The study showed that differences in transport metrics occur in adjacent river reaches and that mowing of macrophytes can increase the transient storage area.

Particle-associated organic contaminant and cytotoxicity transport in a river during storm events

Clarissa Glaser; Beate I. Escher; Michelle Engelhardt; Yuyuan Liu; Martin Krauss; Maria König; Rita Schlichting; Christiane Zarfl; Stephanie Spahr

This study investigated the mobilisation and transport of particle-associated organic contaminants and their cytotoxicity in a river during storm events. Cytotoxicity determined in cell-based bioassays correlated linearly with total suspended solids concentration in a river, demonstrating that particle-associated contaminant mixtures can strongly affect river water quality during rain events.

Multispecies assemblages and multiple stressors: synthesizing the state of experimental research in freshwaters

Fengzhi He; Roshni Arora; India Mansour

This is a review of multiple-stressor research in freshwaters, particularly studies that have experimentally manipulated multiple stressors and measured responses of multispecies assemblages. There is a gap between biotic interactions under multiple stressors and ecosystem recovery pathways after restoration, indicating a disconnect between multiple stressor research and environmental practice.

Large-scale sampling of the freshwater microbiome suggests pollution-driven ecosystem changes

Katrin Premke ... Katja Felsmann ... Sibylle Schroer ... Eric Hübner ...Christopher C.M. Kyba; Michael T. Monaghan; Franz Hölker

Citizen scientists sampled more than 600 freshwaters in Germany. This unique data set provides evidence of 3 trends: first, microorganisms in the sediment show signs of chemical stress and antibiotic resistance in their genetic material. Second, excessive artificial lighting at night alters the species composition of  microorganisms. And third, all studied water bodies emit greenhouse gases.

Multiple angle observations would benefit visible band remote sensing using night lights

Christopher C.M. Kyba; Martin Aubé; Salvador Bará; Andrea Bertolo; Constantinos A. Bouroussis; Stefano Cavazzani; Brian R. Espey; Fabio Falchi; Geza Gyuk; Andreas Jechow; Miroslav Kocifaj; Zoltán Kolláth; Héctor Lamphar; Noam Levin; Shengjie Liu; Steven D.

The authors propose that next generation night-time remote sensing missions should consider multiple angles for observations in the visible band. They demonstrate via modeling and examples how the proposed method would leverage light pollution studies and unlock new applications for night-time remote sensing.

Divergent roles of iron and aluminum in sediment organic matter association at the terrestrial–aquatic interface

Kai Nils Nitzsche; Zachary E. Kayler; Katrin Premke; Arthur Gessler; Rota Wagai

The authors hypothesized that the variation in sediment redox and pH regime govern how iron (Fe) a.aluminum (Al) interact with organic matter (OM) in near-surface mineral sediments.The reactive monomeric Al preferably binds with organic ligands from less-decomposed OM under acidic and anoxic conditions. Low-crystallinity Fe formed under oxic conditions binds with more microbially-processed OM.

A plea for a worldwide development of dark infrastructure for biodiversity: practical examples and ways to go forward

Romain Sordello; Samuel Busson; Jérémie H. Cornuau; Philippe Deverchèrd; Baptiste Faure; Adrien Guetté; Franz Hölker; Christian Kerbiriouh; Thierry Lengagnei; Isabelle Le Viol; Travis Longcore; Pascal Moeschler; Jessica Ranzoni; Nicolas Raymn; Yorick Reyjol; Yoann Roulet; Sibylle Schroer; Jean Secondii; Nicolas Valet; Sylvie Vanpeene; Sébastien Vauclair

The authors advocate the worldwide development of a dark infrastructure. This refers to areas and corridors without excessive artificial light at night that protect biodiversity from light pollution. A guide to getting there.
