Effects of peak exposure scenarios on Gammarus fossarum using field relevant pesticide mixtures

The relative importance of diet-related and waterborne effects of copper for a leaf-shredding invertebrate

“…This seems worrying given that detritus can be a significant sink for metals and organic contaminants (e.g., Bundschuh et al, 2013;Sridhar et al, 2001;Zubrod et al, 2015a). To safeguard the integrity of aquatic ecosystems, it thus seems necessary that prospective risk assessments cover all significant exposure routes including dietary uptake.…”

“…However, in the European Union the assessment of dietary exposure is recommended exclusively for fish (EFSA, 2013), although ecosystem functioning may be critically affected as a result of dietary exposure of organisms at lower trophic levels (cf. Bundschuh et al, 2013). Moreover, testing for dietary exposure is triggered by extremely high octanol/water partition coefficients (log P ow > 6; EFSA, 2013).…”

Gammarus fossarum (Crustacea, Amphipoda) as a model organism to study the effects of silver nanoparticles

“…Gammarus fossarum is increasingly used in ecotoxicology as test species due to its wide distribution (Barnard and Barnard, 1983) all over Europe and all over Luxembourg, high abundance (Felten et al, 2008a;Kunz et al, 2010), clear sexual dimorphism, easiness of collection and handling and its sensitivity to a large range of toxicants (Issartel et al, 2005;Xuereb et al, 2011;Bundschuh et al, 2013;Arce Funck et al, 2013;Besse et al, 2013). G. fossarum plays a major functional role in ecosystems in leaf litter breakdown processes, freshwater food chains and nutrient cycling (Forrow and Maltby, 2000;Kelly et al, 2002;MacNeil et al, 1997).…”

Uptake and elimination kinetics of the biocide triclosan and the synthetic musks galaxolide and tonalide in the earthworm Dendrobaena veneta when exposed to sewage sludge

“…Toxic effects are likely to occur at peak concentrations, and even a short duration of peak exposure may cause chronic and genetic effects [24]. This is particularly relevant for aggregated amendments and compounds that are rapidly degraded.…”
