Statistical analysis
Results were allowed to relate the heavy metal levels with the tissue type, examined to determinate descriptive
parameters such as mean and standard deviation and compared using variance analysis (ANOVA) and a
comparison of means test, setting a significance level of 0.05 (Zar, 1984). Comparisons were performed using the
statistical software IBM SPSS Statistics version 21.

individuals collected from the southern of the Black Sea. Values with different letters represent significant differences (p<0.05)
between the mean values of the levels of each heavy metal in each of the tissues
