Abstract: Obtaining reliable trace element reference values in tissues and fluids from inhabitants of the European Union relies on the availability of standardised and harmonised protocols for the statistical treatment of the data on trace element levels in general European populations. In this context, cadmium was measured in the blood (BCd) of 514 Italian inhabitants from the Lombardy region and the results statistically treated and presented according to a procedure which includes: simple descriptive statistics and graphical analysis such as stem and leaf and box-plot representations; p-p plot, Shapiro-Wilk and Lilliefors tests for normality, analysis of variance, and step wise multiple regression analysis. Tentative reference intervals for BCd based on the log transformation of the data are 0.14-1.82 ug Cd/l.
