Objective Aim of this study is to investigate the relation between intensities of some blood metals as Fe, Zn, Pb, and Cd, in both mothers and their newborn, and their effects on the newborn birth weight, height as well as head circumference using Laser Induced Breakdown spectroscopy LIBS as a non invasive technique.
Methods 34 pregnant women and their normal birth weight newborn (NBW, group I) were recruited and matched against 34 pregnant women and their low birth weight newborn (LBW, group II). Blood samples were collected from the umbilical cords of the newborns from both groups and venous blood samples were taken from their mothers after delivery. Samples were prepared then exposed to laser. We used the laser induced breakdown Spectroscopy (LIBS), to analyze the metal intensity of (Cd, Pb, Zn, and Fe), for each sample for both mother and her infant.
Results There were significant differences between both groups regarding Cd, Pb, Zn, more in group I, while there were no significant differences in both groups in the mother and her newborn regarding to Fe. There were significant differences regarding Cd, Pb, Zn, more in group I, while no significant differences in both groups in the mother and her newborn regarding to Fe.
Conclusion We found that there was significant negative correlation between birth weight and maternal blood intensity in both groups. We found positive correlation between maternal and newborn blood metals and a negative correlation between intensity of both maternal and infant blood metals regarding weight in both groups.
