“…Analysis of Variance (ANOVA) showed that the quantal response of P. reticulata differs signifi cantly (p<0.05) among different concentrations at 24, 48, 72 and 96h of exposure to both toxicants. The results agreed with those of several authors (Anastácio et al, 2000;Morrall et al, 2003;Nalecz-Jawecki et al, 2003;Liwarska-Bizukojc et al, 2005) who observed that detergent products and their ingredients were relatively toxic to aquatic life. These results were also corroborated by Pettersson et al (2000) who reported that anionic surfactants give toxic effects to various aquatic organisms at the concentrations from 0.0025 to 300mg/L.…”

(MFLS) were evaluated for the Poecilia reticulata in laboratory bioassays. The acute toxicity was evaluated for 96 h while the sub-lethal effects of the two surfactants on the biochemical parameters of P. reticulata were investigated for a 6 -day exposure period. The derived toxicity indices showed that the FLS (96hLC 50 = 0.062ml/L) was 1.37 times more toxic than the MFLS (96hLC 50 = 0.085ml/L) against P. reticulata. Analysis of variance (ANOVA) showed signifi cant difference (p<0.05) in the quantal response of P. reticulata to different concentrations of FLS and MFLS at 24, 48, 72 and 96 h of exposure. The mean tissue protein, triglyceride, glucose and cholesterol ranged from (21.04 -48.54 and 18.06 -58.54mg/dl), (87.43 -154.95 and 85.63 -144.28mg/dl), (33.95 -55.03 and 32.76 -53.15mg/dl) and (37.30 -65.38 and 37.12 -58.11mg/dl) for FLS and MFLS respectively. ANOVA showed signifi cant difference (p<0.05) in the biochemical response of P. reticulata to FLS and MFLS. The implications of these fi ndings are highlighted.

“…With respect to other aquatic crustaceans, Artemia is more resistant toward a variety of pollutants [37,38]. For example, toxicity of Cd for Daphnia magna was four times greater than A. fransiscana [39], but concerning the sensitivity of heavy metals, intra and even inter-species differences has been confirmed among several species of Artemia [40].…”

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.

“…In spite of this fact, several criticisms against their suitability for such purpose have been published (Persoone & Wells, 1987;Nunes et al, 2006). The most important of them is the lower sensitivity of the Artemia species to several chemical or physical agents in comparison to the other invertebrate test organisms (Sorgeloos et al, 1978;Song andBrown, 1998, Okamura et al, 2000;Guerra, 2001;Nalecz-Jawecki et al, 2003;George-Ares, et al, 2003;Mayorga et al, 2010). The second disadvantage is a decreased solubility of some chemical substances in saline or sea medium (e.g.…”
