AbstractLaboratory experiments were conducted in order to evaluate the behavior of mercury in an aquatic environment. Two dynamic systems with repeated simultaneous sampling of water and all available trophic organisms were adopted for a period of 4 weeks and 10 weeks, respectively. The organisms used in both systems were algae predominantly Chlorella sp., Daphnia moina, fresh water mussels (genus Vivipara) and fishes Puntius gonionotus which fed on daphnia and algae, and Gyrinochelus aymonieri which fed mostly on algae. Thiosulfate complexes mercury was used as contaminant at concentration of 500 µg/i . The mercury was accumulated substantially higher by organisms in the experiment I in which the flow rate is given 7-14 times higher than in experiment II. Only fish in the experiment II provided much information on biomagnification, where the mercury have been magnified by fish over time but not in the experiment I because the species were exposed for an insufficient period of time which yielded in-adequate information to evaluate the biomagnification process.
