Journal ArticleDOI
Organic chemicals jeopardize the health of freshwater ecosystems on the continental scale
Egina Malaj,Egina Malaj,Peter C. von der Ohe,Matthias Grote,Ralph Kühne,Cédric P. Mondy,Philippe Usseglio-Polatera,Werner Brack,Ralf B. Schäfer +8 more
TL;DR: It is provided strong evidence that chemicals threaten the ecological integrity and consequently the biodiversity of almost half of the water bodies on a continental scale, based on the analysis of governmental monitoring data from 4,000 European sites.
Journal ArticleDOI
Pesticides reduce regional biodiversity of stream invertebrates
TL;DR: The current ecological risk assessment of pesticides falls short of protecting biodiversity, and new approaches linking ecology and ecotoxicology are needed.
Journal ArticleDOI
Salinisation of rivers: An urgent ecological issue
Miguel Cañedo-Argüelles,Ben J. Kefford,Christophe Piscart,Narcís Prat,Ralf B. Schäfer,Claus-Jürgen Schulz +5 more
TL;DR: Management of secondary salinization should be directed towards integrated catchment strategies and identifying threshold salt concentrations to preserve the ecosystem integrity, and the implications of this issue for human society need to be seriously considered.
Journal ArticleDOI
Effects of pesticides on community structure and ecosystem functions in agricultural streams of three biogeographical regions in Europe
TL;DR: It is demonstrated that pesticides may influence the structure and function of lotic ecosystems and that the SPEAR approach can be used as a powerful tool in biomonitoring over large spatial scales.
Journal ArticleDOI
Fungicides: An overlooked pesticide class?
Jochen P. Zubrod,Mirco Bundschuh,Mirco Bundschuh,Gertie Arts,Carsten A. Brühl,Gwenaël Imfeld,Anja Knäbel,Sylvain Payraudeau,Jes J. Rasmussen,Jason R. Rohr,Andreas Scharmüller,Kelly L. Smalling,Sebastian Stehle,Ralf Schulz,Ralf B. Schäfer +14 more
TL;DR: It is shown that fungicides occur widely in aquatic systems, that the accuracy of predicted environmental concentrations is debatable, and that fungicide exposure can be effectively mitigated, andThat fungicides can be highly toxic to a broad range of organisms and can pose a risk to aquatic biota.
