Lead is a neurotoxicant with well documented and lasting adverse health effects. Primary prevention strategies that control or eliminate lead sources before children are exposed remain the pre-eminent public health approach to the problem of lead poisoning and are the only effective way to prevent the neurodevelopmental and behavioral abnormalities associated with lead exposure. Unfortunately, though, hundreds of thousands of children already have experienced blood lead levels known to impair academic performance and affect life success. Thus, tertiary prevention (that is, strategies that restore individuals to an optimal level of functioning after damage is done) is also needed. Recognizing the need to ensure that children affected by lead receive timely and appropriate educational interventions, the Centers for Disease Control and Prevention and the Advisory Committee on Childhood Lead Poisoning
Prevention convened a work group of recognized experts to review the existing scientific evidence for adverse effects of blood lead levels on academic performance and describe actionable steps that clinical and public health practitioners, parents, and educators can take to ensure that the children receive such services.
