“…The different degrees of induction for different metals in sandhoppers agree with the data reported by Ungherese and Ugolini (2009) regarding LC 50 In fact, for T. saltator Hg was the most toxic metal followed by Cu and Cd (Ungherese and Ugolini 2009). A similar dose-dependent response was recorded in the freshwater amphipod E. echinosetosus exposed to a range of Cd concentrations (0.1-1 ppm) for 24 and 48 h (Martinez et al 1996). The fast induction of MTs in T. saltator has also been reported in many crustacean species, e.g., in the copepod Tigriopus brevicornis (Barka et al 2001) after 1 day of exposure to a range of doses of Cu, Hg, Cd, Ag, Ni, or Zn, in the cladoceran Daphnia magna after 2 h of exposure to Cd (Bodar et al 1998), and in the crayfish Procambarus clarkii and the phyllopodan Artemia sp.…”

“…A similar result has been reported in the amphipod T. saltator exposed to different concentrations of Cu in the laboratory for 3-5 days (Ungherese et al 2007). Instead, the freshwater amphipod Echinogammarus echinosetosus showed a dose-dependent MT induction after 24 h of exposure to Cd (Martinez et al 1996). Therefore, as reported for many invertebrates (Amiard et al 2006), the exposure time also affects MT induction in amphipods.…”

“…Therefore, as reported for many invertebrates (Amiard et al 2006), the exposure time also affects MT induction in amphipods. Moreover, in these species a significant decrease of MT concentration has been reported in animals exposed to the highest dose of Cu (O. gammarellus) (Mouneyrac et al 2002) and Hg (E. echinosetosus) (Martinez et al 1996), perhaps due to a general toxic effect of the metal.…”

We investigated metallothionein (MT) induction in the talitrid amphipod Talitrus saltator, a wellestablished biomonitor of trace metal contamination in the supralittoral environment, in response to laboratory exposure to Hg, Cd, or Cu for 3, 6, 24, and 48 h. Analyses were also carried out on animals collected in the wild from six localities along the Tuscan coast with different degrees of trace metal contamination. Animals exposed to Hg in the laboratory showed a strong dose-dependent increase of MT levels after 3 and 6 h; in the following hours (24 and 48 h), the MT concentrations reached control levels, possibly due to a general toxic effect of Hg. For the other metals, MT induction was observed in animals exposed to 10 ppm of Cd and 5 and 10 ppm of Cu. Therefore, despite the positive correlation between MT concentrations and trace metals in sandhoppers collected in the wild, the fast MT response observed in the laboratory suggests an inappropriate use of MT as biomarkers to assess trace metal pollution in coastal areas.

“…The production and role of metallothioneins varies widely among different species of amphipods exposed to metals [37,[44][45][46]. The lack of organism recovery in the period between pulsed exposures in the current study may indicate that the M. plumulosa species have inadequate detoxification mechanisms, including metallothionein production [4,40,47].…”

The concentrations of metal contaminants often fluctuate in estuarine waters; yet we have limited knowledge about the effects of intermittent exposures on estuarine organisms. Using 10-d lethality bioassays with the epibenthic amphipod Melita plumulosa, different combinations of intermittent (pulsed) dissolved Cu exposure were investigated, varying Cu concentration, pulse duration, and time between pulses. Negligible organism mortality was observed immediately after single 12- to 62-h duration pulsed exposures of 100 to 900 µg/L dissolved Cu. However, delayed mortality was observed in the subsequent 96-h nonexposure period, after which negligible additional mortality occurred during the remainder of the 240-h tests. For multiple pulsed exposures, increasing the time between pulses from 0 to 144 h did not result in significantly different mortality rates for 300 and 400 µg/L dissolved copper, indicating that the organisms did not recover between pulses. Organism mortality exhibited a strong relationship with the time-averaged concentration (TAC) resulting from the combination of exposure concentration and duration. The lethal concentration to 50 (LC50), 20 (LC20), and 10% (LC10) (95% confidence interval) of the test population for the combined TAC exposure-survival data were 86 (71-103), 44 (30-64), and 30 (18-49) µg Cu/L, respectively, which were similar to the respective values of 100 (87-114), 55 (43-70), and 39 (28-54) µg Cu/L determined for continuous exposure. The results from the current study support the use of analytical techniques capable of determining the time-averaged concentration of metals, because they will more accurately predict the effects of toxiciants on organisms than single time-point measurements.

“…Gammarus pulex (Linnaeus, 1758) is the most commonly used fresh water amphipod species in ecotoxicology since it has a wide distribution area in streams of Europe and Northern Asia and is fairly easy to maintain in the laboratory (Karaman and Pinkster 1977;McCahon and Pascoe 1988a). However, the sensitivity of other freshwater gammarid species to toxicants has been studied less frequently (but for examples see, for instance, Martinez et al 1996;Alonso and Camargo 2006;Pestana et al 2007;Chaumot et al 2009;Alonso et al 2010;Sroda and Cossu-Leguille 2011).…”

A comparison of the short-term toxicity of cadmium to indigenous and alien gammarid species

Amphipods play an important role in many aquatic ecosystems and are commonly used in ecotoxicology and ecosystem health assessment. Several alien gammarids have been introduced in many regions of the world during the last decades. In this study, we investigated if differences in cadmium sensitivity occurred between (1) different species belonging to the family Gammaridae and (2) different populations of the same species originating from a polluted or a non-polluted site. The acute cadmium toxicity to two indigenous (Gammarus pulex and Gammarus fossarum) and four alien (Dikerogammarus villosus, Echinogammarus berilloni, Gammarus roeseli and Gammarus tigrinus) gammarids occurring in Belgium was tested. Significant differences (P < 0.05) in median lethal concentrations (LC(50)) were found between the different species, with 72 h-LC50s ranging from 6.3 to 268 μg/l and 96 h-LC50s from 4.7 to 88.9 μg/l. No clear trend in Cd sensitivity was found when comparing indigenous and alien gammarids. D. villosus, an alien invasive species, was the most sensitive to Cd toxicity and E. berilloni, another alien species, the least sensitive. In addition, larger Gammarid species were more sensitive to Cd toxicity than smaller ones. No significant differences were found between populations of the same species originating from metal polluted sites or non-polluted sites. Overall, our results showed that considerable differences in Cd sensitivity exist between gammarid species, which should be taken into consideration in environmental risk assessment and water quality standard setting. Finally, our data suggest that alien gammarids would not have an advantage over indigenous gammarids in Cd contaminated environments.
