Abstract
Hair samples from 31 learning disabled and 22 normal children were analyzed for content of 14 elements. Significant group differences were determined and a discriminant function was completed which separated the groups with 98 per cent accuracy. Elevated lead and cadmium content in the learning disabled group is viewed as being of particular importance.Entities:
