The aim of this study was to determine the content of magnesium, copper, cadmium and iron in umbilical cord blood of the newborns depending on the number of pregnancies. It was established correlations between average concentrations these metals in cord blood and newborns parameters. The study material was collected immediately after delivery from the Department of Obstetrics and Gynecology in Bytom. The cord blood was taken from 99 women between 29-40 years old. Women were divided into two groups: nulliparous and multiparous. The concentration of metals in the cord blood was determined by flame atomic absorption spectrometry (FAAS). The conducted study demonstrates that magnesium, copper, cadmium and iron were noted in all tissues, both nulliparous women and multiparous mothers. The maximum concentration of cadmium in umbilical cord blood was observed among multiparous mothers (2.229 mg pe kg d.m.). In group of nulliparous women was observed higher concentration of Fe, Mg and Cu in umbilical cord blood than in multiparous mothers. It was noted some statistically significant correlation between iron, copper and newborns parameters. Parity influences the concentration of cadmium in umbilical cord blood with higher level found in multiparous women. Average content of iron in cord blood did not decrease with parity, it indicate that this element is preferentially taken up by the child.
