Comparison of arsenate and cadmium toxicity in a freshwater amphipod (Gammarus pulex)

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

“…( Lambrechts et al, 1997;Usseglio-Polatera et al, 2000) as well as physiological parameters (e.g. life cycle) (McCahon and Pascoe, 1988;Alonso et al, 2010;Vellinger et al, 2012;Arce Funck et al, 2013), sampling dates (June vs July), water quality in the field and food availability (Heugens et al, 2006). The differences in toxicity observed for the different AgNPs (20 nm and 200 nm obtained by chemical synthesis and AgNPs 23 nm and 27 nm obtained by "green" synthesis) could be partially explained by their different dissolution in exposure medium.…”

“…The Excel macro REGTOX allowed us to estimate both LC50 values using Hill model (Vindimian et al, 1983) and their 95% confidence intervals (Vellinger et al, 2012). 95% confidence intervals were considered for identifying significant differences existing between Gammarus populations.…”

Acanthocephalan parasites: help or burden in gammarid amphipods exposed to cadmium?

“…Cadmium accumulation in gammarids has been described in the literature for G. pulex (Stuhlbacher and Maltby 1992;Felten et al 2008;Vellinger et al 2012), G. locustra (Clason and Zauke 2000), or G. oceanicus (Zauke et al 2003), but no study has been devoted to G. roeseli and only a few ones have investigated the influence of parasite on the metal bioaccumulation in the host. The present work highlighted that infected G. roeseli accumulated less cadmium in their body-whole than uninfected ones, conducting to the weakest BCF in P. minutus-infected gammarids.…”

Effects of two PBDE congeners on the moulting enzymes of the freshwater amphipod Gammarus pulex

“…Gammarids are known to be sensitive to pollutants and can easily be used in laboratory and field studies (Kunz et al, 2010). Hence, many ecotoxicological studies have been carried out using gammarids to evaluate impacts of xenobiotics (Leroy et al, 2010;Sornom et al, 2010Sornom et al, , 2012Gismondi et al, 2012aGismondi et al, , 2013Vellinger et al, 2012). However, to our knowledge, no study has been devoted to PBDEs effects on Gammarus sp., although this specie offers advantages (e.g.…”
