low. In fraction D the highest values of yield were confirmed
in samples PM2 64.1 % and SM 55.2 %.
The Fig. 2. presents the distribution of nickel in fractions.
The highest concentration of nickel was determined in
fraction D, where the highest yield was in sample PM4 80 %
and the least in sample SP 16 %. In the other forms, the nickel
content in yield was very low.
According to Fig. 3., the highest concentrations of lead
were found in fraction A, where the highest values of yield
were in samples PM 3 64.2 % and PM 2 – 1 (54.4–51.6 %).
In fraction B–C, the content of was in low percentage yield
and the yield was higher in fraction D.
The results of yield are given in Table III, where the total
content of particular heavy metals Cu, ni, Pb in sediments
were compared with the sum of metal concentrations in fraction
A–D from sequential extraction. In sample PM2, 100 %
yield of copper was determined.
