“…Na + and Cl -) has been recognised to be the major response of fish to acid stress (McDonald et al 1989, Potts & McWilliams 1989, Wood 1989, Gonzales et al 1997. Similar results have been reported in crayfish (Appelberg 1985, Fjeld et al 1988, McMahon & Stuart 1989, Jensen & Malte 1990, gammarids (Rupprecht 1992) and molluscs (Pynnönen 1991). Surprisingly, and despite the numerous papers reporting detrimental effects of acidification on invertebrate communities, few studies have been performed on the ecophysiology of smaller acid-sensitive macroinvertebrate species.…”

“…Numerous studies have shown clear evidence of a failure to regulate blood or haemolymph Na + and Cl -levels in acidstressed fish, clams (Unionidae) and decapods (Massabuau 1985, McMahon & Stuart 1989, Pynnönen 1991, Gonzales et al 1997. However, most of the studies have focused on large species, and relatively little is known about physiological responses in smaller acidsensitive species of macroinvertebrates.…”

“…Loss of extracellular ions (i.e., Na + and Cl -) has been recognized as a major response in fish to acidic stress (Wood 1989). With respect to invertebrate organisms, similar responses have been reported in crayfish (McMahon & Stuart 1989, Jensen & Malte 1990) and molluscs (Pynnönen 1991). In spite of the numerous papers reporting detrimentral effects of acidification on invertebrate communities, surprisingly few studies have been carried out on the ecophysiology of smaller acid-sensitive macroinvertebrate species.…”

Anthropogenic sources increase freshwater salinity and produce differences in constituent ions compared with natural waters. Moreover, ions differ in physiological roles and concentrations in intracellular and extracellular fluids. Four freshwater taxa groups are compared, to investigate similarities and differences in ion transport processes and what ion transport mechanisms suggest about the toxicity of these or other ions in freshwater. Although differences exist, many ion transporters are functionally similar and may belong to evolutionarily conserved protein families. For example, the Na+/H+-exchanger in teleost fish differs from the H+/2Na+ (or Ca2+)-exchanger in crustaceans. In osmoregulation, Na+ and Cl− predominate. Stenohaline freshwater animals hyperregulate until they are no longer able to maintain hypertonic extracellular Na+ and Cl− concentrations with increasing salinity and become isotonic. Toxic effects of K+ are related to ionoregulation and volume regulation. The ionic balance between intracellular and extracellular fluids is maintained by Na+/K+-adenosine triphosphatase (ATPase), but details are lacking on apical K+ transporters. Elevated H+ affects the maintenance of internal Na+ by Na+/H+ exchange; elevated HCO3− inhibits Cl− uptake. The uptake of Mg2+ occurs by the gills or intestine, but details are lacking on Mg2+ transporters. In unionid gills, SO42− is actively transported, but most epithelia are generally impermeant to SO42−. Transporters of Ca2+ maintain homeostasis of dissolved Ca2+. More integration of physiology with toxicology is needed to fully understand freshwater ion effects.
