“…Blust et al (1992) investigated the effect of salinity on cadmium uptake with the brine shrimp Artemia fransiscana and found a decrease in the cadmium uptake with increasing salinity. De Roberts (1988, 1994) and Roast et al (2001) also earmarked Cd 2' as the primary toxic species for A. bahia and N. integer .…”

Water quality criteria are mainly based on data obtained in toxicity tests with single toxicants. Several authors have demonstrated that this approach may be inadequate as the joint action of the chemicals is not taken into account. In this study, the combined effects of six metals on the European estuarine mysid Neomysis integer (Leach, 1814) were examined. Acute 96-h toxicity tests were performed with mercury, copper, cadmium, nickel, zinc and lead, and this as single compounds and as a mixture of all six. The concentrations of the individual metals of the equitoxic mixtures were calculated using the concentration Á/addition model. The 96-h LC50's for the single metals, at a salinity of 5, ranged from 6.9 to 1140 mg/l, with the following toxicity ranking: Hg /Cd /Cu /Zn/Ni /Pb. Increasing the salinity from 5 to 25 resulted in lower toxicity and lower concentrations of the free ion (as derived from speciation calculations) for all metals. This salinity effect was strongest for cadmium and lead and could be attributed to complexation with chloride ions. The toxicity of nickel, copper and zinc was affected to a smaller extent by salinity. The 96-h LC50 for mercury was the same for both salinities. In order to evaluate the influence of changing salinity conditions on the acute toxicity of metal mixtures, tests were performed at different salinities (5, 10, 15 and 25). The 96-h LC50 value (1.49 T.U.) of the metal mixture, at a salinity of 5, was clearly lower than the expected value (6 T.U.) based on the nonadditive hypothesis, thus confirming the additive effect of these metals in the marine/estuarine environment. Changing salinity had a profound effect on the toxicity of the mixture. The toxicity clearly decreased with increasing salinity until 15. Higher salinities (25) had no further influence on the 96-h LC50 of the mixture which is situated at a value between 4.4 and 4.6. Finally, the relative sensitivity to the selected metals was compared with the relative sensitivity of the commonly used mysid Americamysis ( 0/Mysidopsis ) bahia . #

“…A rise in the salinity was followed by lower Cd toxicity and accumulation in A. fransiscana [47]. The tendency of the metal to form complexes with the chloride ion in saline environments makes the metal less available from solution and may largely explain the inverse relationship between Cd accumulation and salinity in the marine environment.…”

Background: Artemia urmiana are small crustaceans that because of its non-selective filter feeder pattern potentially may absorb high level of heavy metals through their living environment. In this study, the effects of different levels of cadmium and copper on survival, catalase activity and metals bioconcentration rates in A. urmiana nauplii have been investigated. Methods:The research was carried out in February 2012 at University of Tehran, Tehran, Iran.First experiment was conducted in nine concentrations with six replication, then LC 50 and probable interactions between experimental metals were evaluated. In the second experiment, concentrations of metals absorbed by Artemia and catalase activity were measured based on the acute toxicity indices, including NOEC, LOEC and LC 50 at individual and mixed concentrations. Results:The toxicity of copper sulphate (LC 50 = 29.87) was 2.5 times greater than cadmium chloride (LC 50 =79.08) and the toxicity interaction between cadmium and copper was synergistic. The rate of copper uptake in Artemia was higher than cadmium and increased concentration of heavy metals significantly decreased the bioconcentration factor. Comparison of mixed and individual concentrations showed that cadmium significantly decreased copper uptake, while it seems that cadmium bioconcentration was improved consequently. Biochemical analysis showed that the catalase activity was affected undesirably in different individual and mixed concentrations; however, these changes were not significant. Conclusion:A. urmiana nauplia seems to be highly resistant toward cadmium and copper in their culture medium and demonstrated excessive potential for uptake of heavy metals from their rearing environment.

“…The lower efflux rate in higher salinity might reflect the osmotic regulation involving freshwater clam, C. fluminea to maintain the composition of the internal environment within certain physiological limits (Blust et al 1992). Acclimation to higher salinity may involve the alteration of the exchange surfaces (e.g.…”

“…Many studies have evaluated the effect of salinity on the dissolved metal uptake (Fischer 1986;Nugegoda and Rainbow 1989a, b;Blust et al 1992;Chan et al 1992;Bjerregaard and Depledge 1994;Rainbow and Kwan 1995;Lee et al 1998). Euryhaline organisms living at low salinities generally contained higher concentrations of metals than those living at higher salinities (Phillips 1980).…”

“…The major ion (e.g. Ca 2+ and Mg 2+ ) concentration in the solution can also influence the Cd and Zn uptake by changing the permeability of the epithelial structures, competing for binding sites with the apical membrane surfaces, and decreasing metal transfer from the epithelium to the blood with increasing intracellular levels of calcium (Blust et al 1992;Bjerregaard and Depledge 1994;Rainbow 1995). In contrast, the reduced salinity below the optimal range for marine animals can decrease ionic and osmotic fluxes between cells and surrounding media and also reduce the uptake of dissolved trace metals by impairing the clearance rate due to osmostic stress (Depledge 1990).…”

− Laboratory radiotracer experiments were conducted to determine assimilation efficiencies (AE) from ingested algal food and oxic sediment particles, uptake rates from the dissolved phase, and the efflux rates of Cd, Cr and Zn in the Asiatic clam Corbicula fluminea. Among three elements, AE from both algal and sediment food was greatest for Cd, followed by Zn and Cr. The AEs of tested elements from algal food (Phaeodactylum tricornutum) were consistently higher than those from sediments at a given salinity and temperature. The influence of salinity (0, 4 and 8 psu) and temperature (5, 13 and 21 o C) on the metal AEs was not evident for most tested elements, except Cd AEs from sediment. The rate constant of metal uptake from the dissolved phase (k u ) was greatest for Cd, followed by Zn and Cr in freshwater media. However, in saline water, the k u of Zn were greater than those of Cd. The influx rate of all tested metals increased with temperature. The efflux rate constant was greatest for Cr (0.02 d ). The efflux rate constant for Zn in clam tissues depurated in 0 psu (0.017 d −1 ) was faster than that in 8 psu (0.010 d −1 ). Overall results showed that the variation of salinity and temperature in estuarine systems can considerably influence the metal bioaccumulation potential in the estuarine clam C. fluminea. The relatively high Cd accumulation capacity of C. fluminea characterized by the high AE, high dissolved influx rate and low efflux rate, suggested that this clam species can be used as an efficient biomonitor for the Cd contamination in freshwater and estuarine environments.
