通过测量儿童乳牙乳牙和乳牙周牙本质中铅的浓度，对193名市中心黑人儿童的累积铅暴露进行了评估。这些儿童的铅浓度与居住在市中心地区的低收入儿童的人口研究报告的浓度相当。对儿童神经心理测试表现的分析表明，铅水平升高与视觉-运动功能和知觉整合、左右定向和语言抽象的缺陷有关；其他语言能力和运动功能不受影响。通过研究铅与母亲智力、家庭社会经济状况和围产期神经损害指标之间的关系，对这些发现的可能替代解释进行了评估。所有这些关系都不重要。结论是，即使在通常被认为没有症状的水平上，环境中的铅对市中心的儿童也是一种危险。
Cumulative lead exposure in 193 inner-city black children was assessed by measuring lead concentrations in the primary and circumpulpal dentine of their deciduous teeth. Lead concentrations for these children were comparable to the concentrations reported in population studies of low-income children living in inner-city areas. Analysis of the children's neuropsychological test performance showed that elevated lead levels were associated with deficits in visual-motor functioning and perceptual integration, right-left orientation, and verbal abstraction; other verbal abilities and motor functioning were not affected. Possible alternative explanations for these findings were evaluated by examining the relationships between lead and maternal intelligence, family socioeconomic status, and perinatal indicators of neurological impairment. None of these relationships was significant. It was concluded that, even at levels usually regarded as asymptomatic, lead in the environment represents a hazard to inner-city children.
