In this pilot study, we evaluated the usefulness of the alkaline comet assay as a biomonitoring tool at the level of plankton communities affected by varying water quality. Zooplankton was collected in autumn 2007 and spring 2008 in two shallow lakes, one being predominantly polluted with aluminium compounds as result of water treatment process (Lake Njivice; 45°10′ N, 14°30′ E) and the other unpolluted (Lake Ponikve; 45°05′ N, 14°30′ E) used as control. Water and sediment chemistry parameters were assessed at both lake sampling sites. The results indicated that the main pollutant in both matrices was aluminium, whose concentrations exceeded the value of 0.15 mg/L −1 legally accepted for drinking water by Croatian water quality regulations. Plankton composition of the investigated lakes showed that only a few species are dominant and appear at both sites. Cladocerans are represented by Daphnia magna Straus 1820, and copepods by the calanoid Eudiaptomus padanus etruscus (Losito 1901), the cyclopoid Cyclops sp. and dipterans by larvae of Chaoborus flavicans (Meigen 1830). Other species were determined only occasionally and with low abundance. As observed, the comet assay had adequate sensitivity to detect the differences in levels of DNA damage among the dominant zooplankton taxa. Zooplanktons collected in Lake Njivice show a lower degree of DNA integrity compared with animals from the reference lake (Lake Ponikve). Inter-species variability in DNA damage was observed, indicating different genome susceptibility to the same genotoxic pollutants present in the aquatic environment. Furthermore, in the polluted Lake Njivice, seasonal differences in the levels of DNA damage within particular species of zooplankton were also noted. Calanoida, Daphnia and Chaoborus mainly had higher values of all three comet parameters in autumn 2007 than in spring 2008. Feeding modes strongly influenced the level of DNA damage in zooplankton species studied. We assume that the mechanisms of DNA damage and genotoxicity, as Water Air Soil Pollut (

“…E. complanata , has long been used for in situ testing of estrogenic pollutants in studies focusing on physiological endpoints, such as shell growth, tissue weight and expression of the egg yolk protein precursor, vitellogenin (VTG) in males (Gagné et al, 2001; Gagné and Blaise, 2003; Won et al, 2005). Behavioral endpoints have been tested in other bivalve species: inhibition of valve gaping in swan mussels ( Anodonta cygnea ) and burrowing in little neck clams ( Protothaca staminea ) following metal pollution (Kadar et al, 2001; Phelps et al, 1983). In the Asian clam Corbicula fluminea , a body of literature shows altered valve closure patterns as a way to detect aquatic metal contamination (Tran et al, 2003; Chen et al, 2012).…”

The widely used herbicide atrazine (ATR) may have endocrine-associated adverse effects, including on behavior. In this study, 120 adult freshwater mussels, Elliptio complanata, were exposed to ATR at the environmentally-relevant concentrations of 1.5, 15, or 150 μg/L. Burrowing depth was evaluated hourly for 6 hr and at sacrifice animals were sexed by gonad smear. Female controls burrowed overall approximately 30% less than males, the first report of sexual dimorphism in this behavior. Atrazine at 15 μg/L feminized burrowing in both sexes in that exposed animals burrowed 20% less than their same sex controls. Males treated with 1.5 μg /L ATR displayed approximately 20-fold higher vitellogenin (VTG) levels than same sex controls. Higher concentrations of ATR were not associated with increasing effects. A scatterplot showed a weak binomial curve associating low burrowing with high VTG levels. Taken together, these data suggest a non-linear dose-response in behavioral and physiological feminization produced by ATR and support the need to reconsider the widespread use of this compound.

“…Likewise, Sze and Lee (1995) detected increase in mucus production in bivalves exposed to copper and found that the concentration of this metal was six times higher in mucus than in the analyzed tissues; these authors concluded that this is the way mussels keep the metals balanced in the organism once they are secreted with the mucus to the environment. Kádár et al (2001) also suggested that the mucus is important in aluminum exclusion, since high concentrations of this element were found in the pseudofeces of the fresh water bivalve Anodonta cygnea (Linnaeus 1758) under experimental conditions. The increase in mucous cells and, consequently, of mucus found in sites B and C in relation to site A occurred preferentially in the filament frontal zone.…”
