Study of the Age and Sex Dependence of Trace Elements in Hair by Correspondence Analysis

摘要: The aim of the study was to examine potential multidimensional analysis, and in particular correspondence analysis (CA), bringing light influence sex age on trace element (TE) concentrations hair from an unselected French population. Sixteen elements (S, Hg, Se, Zn, Pb, Cd, Ni, Co, Mn, Fe, Cr, Mg, Al, Ca, Cu, Ag) were assayed by inductively coupled argon plasma (ICAP) emission specrroscopy scalp 135 men 346 women. In spite high background noise, CA able reveal differing patterns males females. For instance, this population, higher relative levels essential elements, but also Ag, characterized women’s hair, whereas heavy metals, Fe associated with men’s hair. Al Ag unexplainedly youngest members Cu Co youth seemed give way a predominance Zn maturity. individuals their forties tended be richest Ca these decreased advancing age. Heavy metals (Hg, Fe) accumulated age, Cr independent is manifestly very useful tool for revealing underlying dimensions complex dynamic systems unsuspected relationships among variables. Clearly, significance contents certain especially young, needs investigated both physiological toxicological aspects.
