Abstract:
Seven trace elements (Zn, Cu, Fe, Mn, Cr, Se, Cd) and Mg contents in hair and serum of 210 healthy school children in wuhan were analysed by atomic absorption spectrophotometry except that Se content was determined by cathodic stripping voltammetry. Hair Cu content of males was Lower than that of females significantly. There were significant positive correlation between hair Zn or Mn content and age, and negative correlation between hair Cd content and age, respectively. These demonstrated that the requirements for tract elements were different with age. By comparing the school-aged group with the preschool-aged group and the adolescent group, the hair Zn content was related positively, and Cr and Se negatively, to age. The results by step-wise regression analyses showed that trace elements in hair and serum interacted each other, of which hair Zn content correlated posititvely to serum Zn content. There were correlations among height and hair Mn, Fe, and Zn contents, and between weight and serum Cu content. The results suggested that these elements could influence the developments of height and weight in some degree.
