Results

Several studies have shown that erythrochytes of peripheral blood of fish have a high micronucleous percentage as results of different pollutants exposure.

In my case of study, I compared two sites with different pollutants level, one used as virtual reference and the other as high polluted area. In the latter, the incidence of anthropogenical contaminants was statistically significant, supporting others authors’ data on skeletal abnormalities (due to Cd), bioaccumulation of heavy metals in muscles (Zn and Pb) and chemical contaminants in water and sediments.

Chemical contaminants had an incidence on nuclear abnormalities (measured in FAN ‰M) of 326.4 against 69.4 in the reference site, 4.7 times higher, while the incidence on micronucleous formation (measured in FMN ‰M): was 11.8 against 0.5, more than 23 times higher.
