“…Metal contaminants in the marine environment can have a variety of effects on organisms, ranging from mortality to sublethal effects including behavioral, growth, and reproductive changes, to accumulation in body tissues (Erdem and Meadows, 1980;Mance, 1987;Rainbow, 1990;Langston and Spence, 1995;Roper et al, 1995). In this study, the response of amphipods to copper, zinc, cadmium, nickel, and lead in sediment tests were reported in terms of their survival.…”

The sensitivities of juvenile and adult amphipods to metals (Cd, Cu, Ni, Pb, and Zn) in whole sediment and water-only exposures were compared using a newly developed acute test with the estuarine species Melita plumulosa. Endpoints included survival and bioaccumulation in adults, and survival and growth (body length) in juveniles over 96 h water-only and 10 day sediment exposures. Juveniles were more sensitive than adults to metals, either bound to sediments or in the aqueous phase. Although LOEC values for copper and zinc in juvenile whole-sediment tests (820 and 2290 mg/kg dry weight, respectively) were high in comparison with interim sediment quality guideline values for individual metals (270 and 410 for copper and zinc respectively), they were generally within the range of concentrations found in contaminated sediments in local estuaries. Accumulation of metals, together with the low porewater metal concentrations in whole-sediment tests, indicated that the ingestion of sediment is an important source of zinc and copper and cause of toxicity in this species.

“…Avoidance of contaminants accumulated in environmental components is a widespread phenomenon. Reduced burrowing in the infaunal amphipods Corophium volutator [26], Rhepoxynius abronius , and Eohaustorius sencillus has been noted in contaminated sediments [27], while the amphipod Heterophoxus videns prefers uncontaminated sediments [28]. Behavioral avoidance of habitat‐bound contaminants are likely to enforce inefficient and prolonged searching and foraging patterns on organisms in the field and may impact indirectly on survivorship (through increased risk of predation).…”

Ecological consequences of copper contamination in macroalgae: Effects on epifauna and associated herbivores

Many contaminants of the marine environment are able to chelate to sediments, bind within organic matrices, or be accumulated by organisms such as invertebrates and macroalgae. Marine macroalgae are recognized as effective and efficient bioaccumulators of heavy metals and are sometimes used as bioindicators. Macroalgae support abundant and diverse communities of mobile invertebrates that play key roles in temperate marine environments. However, the potential ecological consequences of the contamination of algae on associated epifauna are yet to be considered. In this study, the brown alga Sargassum linearifolium was experimentally spiked with copper to assess the effects of contamination on epifaunal invertebrates in both field and laboratory assays. Copper contamination greatly reduced the colonization of a variety of epifaunal taxa in the field. Laboratory assays further examined the effects of contaminated macroalgae on habitat preferences, feeding rates, survivorship, and growth in the herbivorous amphipod Peramphithoe parmerong. Adult P. parmerong were less likely to select spiked macroalgae in short-term habitat preference assays and consumed spiked algae at lower rates in feeding assays. In a longer-term (30-d) experiment, survivorship of juvenile amphipods was reduced by up to 75% by contaminated macroalgae, but no effects on the growth of survivors was observed. Heavy metal contamination of macroalgae is a widespread phenomenon that has the potential for substantial negative consequences for associated invertebrate fauna. This issue warrants further investigation by marine ecotoxicologists.

“…Behavior studies have shown that benthic invertebrates, including phoxocephalids, will inhabit nonoptimal sediment if no other choice is available (Meadows and Campbell, 1972;Erdem and Meadows, 1980;Oakden, in press). The White's Point and adjacent Hyperion discharges are the largest sewage outfalls on the California coast, and they impact a broad region of continental shelf.…”

Phoxocephalid amphipods, Rhepoxynius spp , avoided sedlments mixed with domestic sewage, or with concentrations of trace metals (zinc and cadmium) whlch are charactenstic of marine sedlments at waste-water d~s c h a r g e sltes The amphipods burrowed and swam from flne sands enriched with 15 % sewage, and from sewage-contaminated sediment collected near the White S Polnt outfall in southern Callforn~a, USA They also suffered hlgh (> 50 %) mortality In sedlment inoculated with h~g h levels of zinc (610 yg g ') or cadmlum (190 pg g-l), swam and burrowed from sediments with hlgh and moderate concentratlons of either element, and burrowed from sediments with relatively low concentrations of elther element These responses lndlcate that behavioral a v o~d a n c e of contaminated sediment may be important in maintaming population patterns of these phoxocephalids, which are often rare or conspicuously absent around large waste d~scharges
