Reduction of Mercury Accumulation in Carp Tissues (Cyprinus carpio L.) by Natural Organic Matter and Chlorides

Popis výsledku v původním jazyce

In natural waters and in breeding tanks certain substances are naturally present in the water or deliberately added to it. Some of these substances are characterized by the formation of strong complexes with mercury and thus they can reduce the intake of mercury by aquatic organisms. The accumulation of mercury in six selected tissues (skin, scales, kidneys, muscle, liver and gills) of Cyprinus carpio L. in the presence of humic acid and sodium chloride was studied. Carp fingerlings were exposed in fish tanks for 3 days to the bulk solution containing a defined concentration of Hg2+ (1.5 ug/l) and increasing concentration of humic acid (0-5 mg/l) and chloride ions (18-600 mg/l). The fish were not fed during the experiment and mercury accumulated in the carp tissues from fish tank water only. Total mercury content in water and in selected tissues was determined by the atomic absorption spectrometer AMA 254. Increased concentration of both humic acid and sodium chloride caused reduction of mercury accumulation in carp tissues up to 93 and 45%, respectively.
