“…Previous investigations have reported the use of the freshwater mussel Dreissena polymorpha as a bioindicator of water pollution (Kraak et al 1991, Mersch & Pihan 1993. In zebra mussel, as in other bivalve species, the hemocytes are rich in lysosomal hydrolases and are involved in metal transport and detoxication (Giamberini 1993).…”

This study examines the structural changes of the lysosomal system of the hemocytes of the zebra mussel Dreissena polymorpha experimentally exposed to lead and zinc. A cytochemical technique which demonstrated acid phosphatase activity as a lysosomal marker was used on blood cell monolayers. The results indicate that the effects of both metals on hemocytic lysosomes were variable and that no marked linear relationship between lysosomal changes and metal concentration and exposure time was observed. Hemocytes of exposed zebra mussels exhibited enlarged and/or more numerous lysosomes. The use of the lysosomal changes in the hemocytes as a biomarker of contaminant exposure is discussed.

“…Plants were then placed in acid washed mini-autoclaves of Teflon and digested with 15 mL of 7.2 M HNO 3 at 140°C for 4 h. The digest was made up to a final volume of 25 mL with distilled deionized water. Trace metals were measured (n = 5) using atomic absorption spectrophotometry (AAS) and inductivefy coupled plasma emission spectroscopy (ICP-AES) according to the previously described procedures (Goncalves et al, 1992;Mersch et al, 1993b;Mersch and Pihan, 1993). The chlorophyll phaeophytinization quotient (D665/D665a) ratio was measured in the remaining subsample (Lopez and Carballeira, 1990).…”

“…This very broad research field was initially focused by selecting two biological models: a bivalve, the zebra mussel (Dreissenapolymorpha) and a carnivorous fish, the rainbow trout (Oncorhynchus mykiss). These species have been extensively used for biomonitoring programmes in ecotoxicology [1,2] and in radioecology [3,4]; but also for toxicity tests [5,6].…”

Is it relevant to take into account the multipollution context in freshwater radioecology ?

Abstract. Should realism of radioecological evaluations be enhanced while taking into account the deleterious influence of stable pollutants on aquatic organisms which can be physiologically stressed, and therefore can modify their response to radionuclide bioaccumulation? Transfer experiments in a multipollution context involved metals {Cd, Zn), organic pollutants (PCBs, PAHs, oestrogenomimetics) and radionuclides (radioactive isotopes of Co, Cs, and Ag). The chosen biological models were a freshwater bivalve (Dreissena polymorpka) and a carnivorous fish (Oncorhynchus mykiss). Chronic metallic waterborne exposures (1-4 ng/L Cd and/or 170-250 ug/L Zn) led to a decrease in radionuclide bioaccumulation with respect to the reference group (Ag and Cs for fish with respectively -60% and -30%; Co for bivalve with -50%, on average); while no effect was noticed with other radionuclide/organism pairs (Co for fish, Cs and Ag for bivalve). Prior exposure to organic micropoltutants enhanced I7 Co and 1 Cs uptake kinetic parameters from water and retention time in fish; the radionuclide contamination levels of exposed groups were always higher than those obtained from the reference groups (-1-10% to +60% as a function of the organic micropoUutant). Some explanations are given for these first results that underline the relevancy of this new research field.
