Rhepoxynius abronius

LC50 (10-d) for Rhepoxynius abronius 2.31 mg/g organic carbon (Swartz et al, 1997). [Pg.49]

Maintenance of soft-bottom benthic invertebrate communities capable of supporting local fish populations. COPC concentrations in sediment will not result in toxicity to the soft-bottom benthic community. Assess the effect of COPCs in sediment on the survival of two amphipod species (Eohaustorius estuarius and Rhepoxynius abronius). Assess the effect of COPCs in sediment on survival and growth of the polychaete, Neanthes arenaceodentata. Assess in situ changes in benthic community structure (diversity and abundance). [Pg.315]

Few studies have examined the effects of DOC sorption on the uptake of PAHs in marine organisms. When the concentrations of PAHs in porewater were expressed in terms of the free fraction, the BCFs for the amphi-pod Rhepoxynius abronius (a nondeposit feeder) were closer to expected values (Figure 2), indicating that the free PAH in porewater was the bio-available fraction (Meador et al. 1995). Another study found that Atlantic salmon exposed to benzo[a]pyrene in water with a total organic carbon... [Pg.90]

Some studies indicate that species in related taxonomic groups can have different metabolic capacities and that any assumptions based on results from similar species can lead to erroneous conclusions. A comparative study of amphipods [Rhepoxynius abronius (Phoxocephalidae) and Eo-... [Pg.108]

Fig. 16. Bioaccumulation factor (normalized to organism lipid and sediment organic carbon) as a function number of aromatic rings in PAHs. Mean and standard error of the mean BAFi c for PAHs consists of 2-6 aromatic rings. Each mean represents several PAHs and sediments (sites = 7 for amphipod = 5 for polychaete). [See Table 1 for PAHs and ring categories.] Polychaete (Armandia brevis) and amphipod (Rhepoxynius abronius) individuals were exposed to Raritan-Hudson estuary (New York) sediments for 10 d. See Appendix for BAFioc definition. (Data from Meador et al. 1995.)... Fig. 16.
