School of Psychology The Pennsylvania State University University Park, Pennsylvania Trace element and toxic metal concentrations were determined in blood and hair samples obtained from autistic, learning disabled, and control children between the ages of 6 and 12 years. The average hair and blood concentrations of copper, magnesium, zinc, and lead were within acceptable ranges. Serum copper and magnesium, plasma zinc, and whole blood lead concentrations were similar for all groups. Serum copper, plasma zinc, and whole blood lead were identified as predictors of group membership. The results of the present study provide support for inclusion of trace element profiles for diagnostic purposes with developmentally disabled children.
