ABSTRACT
Introduction:
Different biological samples (blood, gallstone, teeth, hair) serve as a biomarker of exposure to metals for many years. This method appeared to be useful not only in clinical medicine, but also in the studies on the environment. Aim. The study is to compare the amount of selected metals in children’s hair residing in industrial and rural areas.
Material and Methods:
Research of occurrence of 12 metals in children’s hair at the age of 7, 10 and 14 living in an industrial (Nowy Bytom town ) and a rural (Strumień town) areas has been presented. Determination of Pb, Cd, Ni, Co Na, K, Mg, Zn, Cu, Mn, Fe and Ca was carried out by atomic absorption spectrophotometry (AAS) using a spectrometer Perkin- Elmer 400.
Results:
In the case of seven-year old children, regardless of gender a common mechanism of co-occurrence was noticed for manganese and calcium, manganese and magnesium, calcium and magnesium, sodium and potassium. Apart from the correlation of metals for the seven-year-old-children mentioned, in case of ten-year old children, an additional correlation between calcium and zinc appears.
Conclusions:
The amount of some metals in the hair with the diversified possibility of interaction between the metals themselves and their relation to gender and age of children revealed different environmental exposure
