“…Supporting to our results, more inhibition rate of Cu compared to Cd and zinc on hatching of A. fransiscana cysts has been reported [42]. Generally, Artemia has a relatively high metallothionein synthesis suggested a reason for lower vulnerability (compared with other aquatic planktonic crustaceans) to heavy metals, especially cadmium [43].…”

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.

Studies have shown that the trophic transfer of certain metals in aquatic systems may be controlled by the internal distribution of metal within prey and that this distribution may be influenced by detoxification mechanisms (i.e. metals bound to metal-binding proteins [metallothioneins, MT] may be more available to predators than metals associated with insoluble cellular constituents). The purpose of this investigation was to examine the interactive effects of Cd and Zn exposure on the accumulation and subcellular distribution of these metals in the brine shrimp Artemia franciscana. Particular attention was given to the partitioning of metals to a subcellular compartment containing heat-stable proteins (HSP) (e.g. MT), heat-denatured proteins (HDP) (e.g. 'enzymes') and organelles, here considered as trophically available metal (TAM). Adult A. franciscana were exposed for 3 d to Cd (control, 1, 89 or 445 µM and Zn-control) or Zn (control, 1, 89 or 445 µM and Cd-control) through solution using radioisotopes ( 109 Cd and 65 Zn) as tracers of stable metals. Following exposure, various operationally defined subcellular fractions were obtained. Increased binding of Cd to HSP resulted in increased partitioning of Cd to the TAM compartment (i.e. TAM-Cd% increased from 57 to 80% over the range of Cd exposures). This increase in TAM was greater than proportional at the 1 µM Cd exposure concentration and could result in a 'bioenhancement' of Cd trophic transfer to predators. Exposure to elevated concentrations of Cd (89 and 445 µM) also resulted in a ~50% suppression in Zn accumulation by A. franciscana. Upon increasing Zn exposure, a shift in the subcellular partitioning of Zn among TAM fractions (from HSP to HDP and organelles) maintained a TAM-Zn% of ~65%. As a verification of the TAM concept, a direct relationship was observed between the partitioning of Cd and Zn to the TAM compartment of A. franciscana exposed to the Cd-control/Zn-control treatment and absorption of these metals by the grass shrimp Palaemonetes pugio.

The present study evaluates the feasibility of using Artemia franciscana in reducing the Ni concentration of synthetic wastewater by the process of bioaccumulation. Metallothionein protein plays a key role in the uptake of nickel by Artemia. Artemia Brine shrimp was exposed to an initial nickel concentration of 40 mg/L. Gradual decrease of nickel was observed from 40 mg/L to 5 mg/L with a removal efficiency of 87.5%. The number of organisms were varied to determine the number for the maximum removal efficiency. Metallothionein protein in Artemia was estimated by the silver saturation method. The physical parameters such as pH were maintained in an alkaline condition of 9-10, temperature was maintained at room temperature and salinity at 30 -35 . These were found to be the optimal conditions for the survival and reduction of nickel by Artemia.
