Table 4.1.3.1 Average values of different metal components in suspended solid, sediment and mussel compartments (mg/kg dry weight) Hg Cd Pb Cr Cu Ni Zn Al As Susp. solids 0,2 3,3 88,7 93,9 125,7 55,4 511,5 32350,0 24,4 Sediment 0,1 2,6 64,0 56,2 90,7 45,6 430,3 20792,6 19,4 Mussels 0,1 5,8 6,1 5,2 36,1 1,8 769,3 583,4 0,5 4.1.4 Comparison of heavy metal data to other results Some heavy metal concentration values referring to the mussel tissues are shown for comparison in Table 4.1.4.1 where the measurements of the Yugoslavian laboratories are given. They found similar figures in case of Hg, Cd, Ni and Zn. They measured lower concentrations in case of Pb, Cr and Cu. It can be concluded that this type of common sampling program is one of the best possibility to harmonize different methods and approaches. Heavy metal compounds were monitored by OERTEL (1996, 1997, 2000a, 2000b) using Dreissena polymorpha as an on-site monitoring kit in the Hungarian Danube section. According to the 7-week period exposure time higher concentrations of Cd, Pb and Ni were measured in Dreissena mussels in the Danube than in Unionidae in the Tisza and its tributaries. However, the amount of Zn and Cu in the Tisza mollusks proved to be much bigger than in the experiments of OERTEL. Several possibilities are given for the comparison of heavy metal content of sediment and mussel tissues regarding those data that were collected during the Bioindicator study (VITUKI/<strong>ICPDR</strong> 2000). In case of mercury the order of magnitude is the same in the mussel species. There were a little higher values measured in the sediment especially from Pancevo section (maximum 0.55 mg/kg Hg in the Danubian sediment) comparing to the average Tisza pollution level (0.1 mg/kg). The measured maximum mercury concentration in the Sajó is highly similar to the maximum value detected in the Velika Morava in 2000. The Cd-level was similar to the ITR measurements in the sediment (2-3 mg/kg) and in case of the mussels, as well (max.: around 10 mg/kg in the Tisza mussels, 8,4 mg/kg in Unio pictorum collected in Tekija). Generally the Cd-content of mussel tissues increased in the Danube downstream direction, especially after Belgrade section, in the Iron Gate Reservoir. These values did not change too much along the Tisza River. The lead and chromium contents of the Danubian sediment and mussels were a little bit higher than in case of the Tisza. Copper concentrations were bigger in the sediment samples and the mussels collected in the Tisza, some Danubian values reached the relevant Tisza figures only in the downstream section. Same statement can be given for the distribution of nickel: both values are very similar to each other in the Danube and Tisza, respectively. 40
