The euryhaline copepod Acartia tonsa was exposed to silver (AgNO(3)) in either the absence or the presence of food (diatom Thalassiosira weissflogii; 2 x 10(4) cells/ml). Standard static-renewal toxicity tests that included ...

Two silver-contaminated diets were prepared by exposing juvenile rainbow trout for 8 d to waterborne silver thiosulfate as Ag at either 0.1 mg/L (low-Ag diet) or 80 mg/L (high-Ag diet). The level of total Ag accumulated ...

Experiments were designed to assess the potential protective effect of the presence of sulfide against the acute (48-h) toxicity of silver(I) to Daphnia magna. Tests were conducted in borosilicate glass beakers (250 ml) ...

In freshwater crustaceans and in both freshwater and marine fish, the key mechanism of acute silver toxicity involves ionoregulatory impairment. An inhibition of the Na+,K+-ATPase located at the basolateral membrane of the ...

Acute silver effects on whole-body ion regulation and Na+,K+-ATPase activity were evaluated in the euryhaline copepod Acartia tonsa. Experiments were run at 20 ◦C, three different salinities (5, 15 and 30 ppt), in either ...

The Biotic Ligand Model (BLM) attempts to predict metal toxicity to aquatic organisms on the basis ofmetal
speciation and effects at the cell surface. Current versions of the BLM for silver and copper consider metal binding ...
