ABSTRACT

Levels of mineral elements (F, Na, Mg, Al, S, Cl, K, Ca, V, Cr, Mn, Fe, Co, Cu, Zn, Se, Br, Rb, Mo, Cd, J, Ba, Hg and Pb), the role of which is well known and documented, were studied in 365 placentas. The significant negative correlations were ascertained between the content of Pb, Cd, F, Hg and the birth weight; the positive correlations were ascertained between some minerals (Mg, Ca, Co, Cu, Zn, Se) that are indispensable for the proper organism functioning and the fetus development.
