“…Varó et al (2006) and Sarabia et al (2003Sarabia et al ( , 2008 reported no adverse effects of metal and pesticide exposure on hatching of Artemia cysts. Bagshaw et al (1986) and Rafiee et al (1986), on the contrary, reported that hatching of dormant eggs was more sensitive to heavy metal exposure than hatched individuals.…”

Laboratory ecotoxicity tests and biomonitoring in aquatic systems are currently based on the active component of invertebrate communities. Even though dormant egg banks are crucial for the long term survival and community dynamics of many aquatic organisms, the effects of anthropogenic activities on dormant egg bank dynamics have rarely been studied. In this study we investigated the effects of two pesticides with a different mode of action (carbaryl and fenoxycarb) on hatching of Daphnia magna dormant eggs (ephippia) as well as on survival, growth and reproduction of the hatched neonates. Dormant eggs were exposed to the pesticides simultaneously to incubation under conditions that induce hatching (long daylight and 20°C). Carbaryl had no negative effects on embryonic development or hatching rate up to concentrations almost 1,000 times the median effect concentration (EC 50 ) of neonate survival in acute tests. Fenoxycarb, however, had a significant dose-related effect by delaying or completely stopping the hatching process and caused severe abnormalities in developing individuals. Both pesticides had significant negative effects on survival and reproduction of the hatchlings. These results indicate that, in addition to inducing mortality of active individuals, pesticides can affect zooplankton communities by altering hatching dynamics and life history traits of hatched individuals. We briefly discuss how such pollution induced changes in the benthic-pelagic coupling could translate into transgenerational effects impacting ecological and evolutionary dynamics.

“…Artemia has many advantages as a marine test organism for investigating the toxicity of chemical compounds (Bagshaw et al, 1986;Persoone and Castritsi-Catharios, 1989;Migliore et al, 1997) or of natural waters and e%uents (Samaras et al, 1998). One disadvantage is that Artemia tends to be fairly resistant to toxic substances (Trie!, 1980).…”

“…On the other hand, it has become an accepted fact that, since chemicals never occur alone in nature, it is most important to investigate the combined e!ects of chemicals on aquatic organisms (Kungolos et al, 1999b). Some studies have investigated the e!ect of single chemicals on Artemia (Bagshaw et al, 1986;Verriopoulos et al, 1986;Persoone and Castritsi-Catharios, 1989;Pandey and MacRae, 1991;Migliore et al, 1997) but few papers have reported on the joint e!ect of chemicals on this marine organism (Verriopoulos et al, 1988).…”

“…There are several reasons for the selection of brine shrimp Artemia as a test organism including the continuous availability of Artemia in the form of dry cysts (Vanhaecke and Persoone, 1984), the low cost, the extensive relevant literature , and the fact that they are su$ciently small to be accommodated in small beakers (Trie!, 1980). Although there are many studies dealing with the e!ect of toxic substances on Artemia (Bagshaw et al, 1986;Persoone and Castritsi-Catharios, 1989;Pandey and MacRae, 1991;Migliore et al, 1997), there is not much information on the bioaccumulation of toxic substances in the body of the organism. The close relationship between toxic e!ects and bioaccumulation has been indicated in a number of bioassays using other test organisms such as Chlorella ellipsoidea (Aoyama et al, 1987), Daphnia magna (Kungolos and Aoyama, 1993), and Saccharomyces cerevisiae (Kungolos et al, 1999a).…”

“…The increased concentration of heavy metals and their mixture are found in natural aquatic ecosystems, so their combined effects on living organisms has become serious concern. There are many investigations on the impact of individual pollutants on Artemia species [6][7][8][9], but a few researchers have considered their mixed effects [10,11].…”

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.
