“…The synergistic effect of metal mixtures of cadmium-tin and chromium-tin have been reported for A. fransiscana [11]. The interaction between Cd and Cu was synergistic in young crab (Chasmagnathus granulata) which is in agreement with current research [44].…”

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.

“…Alternatively, Cd may target some compartment or metabolic route in the organism not affected by the other two metals, which would explain its delayed response (Ferrer et al 2006;Gentile et al 1982;Rainbow 1995). Instances of selective toxicity of Cd to crustaceans, compared to other marine invertebrates such as molluscs and echinoderms have been demonstrated (Nimmo et al 1978;Martin et al 1981), and this is probably due to their specific effects on the development of the exoskeleton in arthropods.…”

Siriella armata (Crustacea, Mysidacea) is a component of the coastal zooplankton that lives in swarms in the shallow waters of the European neritic zone, from the North Sea to the Mediterranean. Juveniles of this species were examined as standard test organisms for use in marine acute toxicity tests. The effects of reference toxicants, three trace metals (Copper, Cadmium and Zinc), and one surfactant, sodium dodecyl sulfate (SDS) were studied on S. armata neonates (\24 h) reared in the laboratory. Acute toxicity tests were carried out with filtered sea water on individual chambers (microplate wells for metals or glass vials for SDS) incubated in an isothermal room at 20 degrees C, with 16 h light: 8 h dark photoperiod for 96 h. Each neonate was fed daily with 10-15 nauplii of Artemia salina. Acute (96 h) LC50 values, in increasing order, were 46.9 lg/L for Cu, 99.3 lg/L for Cd, 466.7 lg/L for Zn and 8.5 mg/L for SDS. The LC(10), NOEC and LOEC values were also calculated. Results were compared with Daphnia magna, a freshwater cladoceran widely used as a standard ecotoxicological test organism. Acute (48 h) LC(50) values were 56.2 lg/L for Cu, 571.5 lg/L for Cd, 1.3 mg/L for Zn and 27.3 mg/L for SDS. For all the reference toxicants studied, the marine mysid Siriella armata showed higher sensitivity than the freshwater model organism Daphnia magna, validating the use of Siriella mysids as model organisms in marine acute toxicity tests.

“…De acordo com Ferrer et al (2006), jovens caranguejos são considerados agentes potencialmente perigosos para a transferência de contaminantes ao longo da cadeia trófica (como alimento para peixes e pássaros), principalmente devido a sua elevada resistência e a sua maior capacidade de bioacumular metais pesados em seus tecidos em relação aos indivíduos adultos. Entretanto, neste trabalho não foram observadas diferenças significativas (ao nível p < 0,5) para os teores de metais em relação ao tamanho dos indivíduos.…”

IntroduçãoUm dos aspectos críticos da introdução de substâncias químicas em sistemas aquáticos é a sua bioacumulação na cadeia alimentar existente nestes compartimentos ambientais, principalmente, no que se refere à contaminação por metais pesados (MARKERT, 1998).No município de Cubatão foram instaladas, a partir da década de 1950, importantes indústrias petroquímicas, metalúr-gicas, fertilizantes, entre outras, aproveitando-se das facilidades do maior porto marítimo do País, o Porto de Santos. O material poluente lançado na região por essas indústrias levou a um processo de degradação ambiental intenso na região. Na década de 1980, a CETESB-Companhia de Tecnologia de Saneamento Ambiental (SP) implantou um programa rígido de controle de poluição ambiental no município de Cubatão, o que reduziu drasticamente a ocorrência de episódios críticos de poluição do ar e tornou possível a recuperação da qualidade das águas. Contudo, estudos realizados pela própria CETESB (1990) utilizando amostras de águas, sedimentos e organismos aquáticos provenientes da bacia do rio Cubatão, constataram ainda a presença de alguns metais pesados e compostos orgânicos em concentrações muitas vezes superiores aos limites recomendados pela WHO (1972). No último relatório publicado pela CETESB (2001), os resultados mostraram uma redução (maior que 50%) da contaminação nos organismos, em relação aos estudos anteriores, para alguns metais (cádmio, chumbo, mercúrio) e alguns compostos orgânicos (hexaclorobenzeno). Como conseqüência, observou-se o retorno de peixes e outros organismos aquáticos, que haviam emigrados da bacia do rio Cubatão. Entretanto, esta transformação ambiental na região não garante a ocorrência de uma recuperação total dos corpos d'águas, já que alguns compostos químicos, entre eles os metais pesados, permanecem nestes ambientes, principalmente nos sedimentos, por longos períodos de tempo AbstractUsually, heavy metals occurrence in aquatic systems is resulting from natural geochemical processes. However, the presence of these chemical elements has considerably increased in the last decades . An example is the case of the Cubatão river basin caused by human activities in that region. In this work, a quantitative analysis of Pb, Cd, Cr, Zn, and Cu content of four blue crab species of the genus Callinectes sp., sampled along the Cubatão river, was carried out using a flame atomic absorption spectrometer (FAAS). 144 blue crab samples from the following species were analyzed: C. danae (63%), C. sapidus (23%), C. bocourti (10.5%), and C. ornatus (3.5%). The C. Sapidus species presented the highest concentration levels for the studied metals. With the exception of Cu, for which the average concentration was 40% higher for the females (p < 0,05), there was no significant variation in the heavy metal content regarding sex and the size of the animals. Except for Cr, for which the average values interval obtained for the 4 species was above the limit allowed by the Brazilian legislation for any type of food, all the other results were...
