avarege value of muscles (2±1 µg/g dry wt.) was detected in spring (2006-2007). The maximum avarege level of
kidney (8±1 µg/g dry wt.) was recorded in spring (2010-2011) and the minimum avarege level of kidney (3±2
µg/g dry wt.) was obtained in autumn (2006-2007) and in winter (2008-2009). The highest mean concentration of
gills (6±2 µg/g dry wt.) was recorded in autumn (2009-2010) and in summer (2010-2011). The maximum mean
concentration of gonads (5±2 µg/g dry wt.) was found in both autumn and spring (2009-2010) (Table 5).
Analyses for the obtained results of metals are shown in Table 6 and Table 7.
