Abstract
Introduction. Copper and iron are necessary elements in the process of creating red blood cells. Copper activates the enzyme catalyzing bond between an iron and a ligand of a porphyrin. Iron participates in the last stage of blood biosynthesis. A deficit of one of these bioelements causes perturbations in the hemoplastic system. Material and methods. Solidification of the elements iron and copper was studied in the hair of school-age children (10-12 years old). The mineral composition of the human organism was analyzed by applying the method of atomic absorption spectrophotometry (AAnalyst 800 Perkin-Elmer Company) using flame atomizer and one-element hollow cathode lamp. Similarities and differences between results we obtained and the results reported by other scientific centers were examined. Results. Medium copper concentration in the tested hair was 8.43 mg/g and the iron concentration was 10.15 mg/g. The level of these two elements was lower compared to the results reported by other researchers. The copper contents in the hair of girls and boys was 8.21mg/g and 8.63mg/g respectively, and iron content was 9.7mg/g and 10.68mg/g respectively.Conclusion. Our results show that the Cu and Fe concentration in the hair of children from Bydgoszcz is lower when compared to data received from other regions of Poland. New research is needed to determine if this results from dietary deficits, and if so, to develop solutions.
