title: Language and speech behaviors of children with undue lead absorption: a review of the literature.
abstract: This article reviews the effects of chronic undue or low lead absorption on the speech and language behavior of children. While the effects of high-level lead poisoning have been documented, the effects of chronic low-lead absorption remain controversial. It is concluded that the evidence supports the presence of speech and language problems in some low-lead level children. The severity, duration, and specific nature of the problems, however, are not clear. Pertinent research issues are addressed.
