“…The observed suppression of Cu uptake at increased sodium concentrations in water is in accordance with the mechanism of branchial Cu toxicity which involves interference with active sodium uptake via apical Na + channel and basolateral transport by Na + /K + -ATPase , . It has been generally accepted that Cd does not interfere with Na uptake pathways.…”

Concentrations of major cations in the medium play an important role in metal accumulation process. Variations in Ca, Na concentrations and pH of the medium had pronounced effects on metal uptake in zebrafish simultaneously exposed to five metals at environmentally realistic concentrations. Largest effects were found in gills (the whole body for Ni). A high level of Zn homeostatic regulation was observed. Addition of 0.1-2.5 mM Ca2+ to the medium had a suppressing effect on Cd uptake. The highest Cu, Pb and the lowest Ni uptake rates were observed atthe middle 0.5 mM Ca concentration. Increase in Na concentrations from 0.5 to 8 mM decreased Cd and increased Ni uptake rates in gills. Both low and high Na concentrations in water had a suppressing effect on Pb uptake. Increase in the pH of the medium promoted Cd and Ni uptakes. Cu and Pb, in turn, exhibited highest uptakes at neutral conditions compared to acidic and alkaline pH due to changes in Cu and Pb speciation. The fact that such changes in metal uptakes occur at low, environmentally relevant concentrations, emphasizes the need for further studies of bioaccumulation and toxicity processes.

“…In contrast to uptake at the gills, zinc uptake at the intestinal level did not appear to be affected by calcium concentration. In a similar study, Pyle and Wood (2008) used radiolabelled copper to study uptake by rainbow trout 10 metals, and they suggest this method as a generic model for metals absorption in aquatic species. The authors also note that this approach is not effective for estimating elimination rate.…”

This review includes works published in the general scientific literature during 2008 on the effects of anthropogenic pollutants on freshwater organisms. It begins with two broad sections: research reviews and broad field studies and surveys. This is followed by reviews of research categorized in sections to reflect the pollutant class. These sections include wastewater, stormwater and non‐point source pollution, nutrients, metals, acid mine drainage, persistent organic pollutants, pharmaceuticals, endocrine disruptors, pesticides, petroleum hydrocarbons, and nanomaterials. The final section includes works describing innovations in the field of freshwater pollution research.

“…Species-specific response to toxicants is a matter of great interest, because it is a critical factor for assessing toxicity as well. Several authors conducted research on species-specific response to a number of toxicants (Pyle and Wood, 2008).…”
