- Abstract
The common blackbird is a model species in toxicological studies in different environments and its egg shells are very often used as a material to determine the content of different elements, including fluorine, which might be environment pollutants. Considering the above, we decided to determine the factors affecting the fluoride ion (F-) content in the egg shells of the common blackbird living at different distances from the chemical plant Grupa Azoty Zakłady "Police" SA, one of the major producers of phosphate fertilizers in Poland. Determination of the Fconcentration was performed using a potentiometric ion-selective electrode. The lowest average F- content was observed in samples from Wełtyń (a noncontaminated area 36 km from the chemical plant) and the highest was in samples from Bartoszewo (a contaminated area 8 km from the chemical plant). Statistically significant differences in F- content were observed in samples taken from Szczecin (16 km from the chemical plant) (p=0.0001) and Wełtyń (p=0.002) compared to the results obtained for the Bartoszewo samples. The month of egg laying had a significant impact on the content of F- in the egg shells in the high F- contaminated area (Bartoszewo) but not in the low F- non-contaminated area (Wełtyń). In the Szczecin area, there were no differences in the F- content of egg shells related to the year, the brood number, and the age of the females.
