Behavioral Assessment of Lead Intoxication*

Current questions about lead exposure focus on the consequences of levels too low to have erupted into blatantly discernible defects. The present paper addresses two sets of interrelated problems derived from this issue. One is how to define the behavioral consequences of asymptomatic lead absorption, and the second focuses on behavioral assessment procedures. Current primary prevention programs emphasize environmental monitoring, and early detection programs emphasize lead body burden measurements. The evaluation of behavioral problems in school children as a function of body burden is rarely performed. Epidemiologic data indicate sufficient natural variability to determine the degree of association between indices of total body burden and behavior. Assessment procedures are described and research suggestions offered that sample concretely defined target behaviors in social environments.
