Background: The adverse effects of lead on behavioral and intellectual development have been recognized for many years. During the past 10 years several studies have shown that lead is toxic to children at levels previously thought to be harmless. Black children living in urban neighborhoods have been identified as being at greatest risk.
Methods: To determine whether children seen in a suburban family practice center were being exposed to lead, voluntary screening of 1-year-old patients was performed.
Results: Over a 7-month period venous specimens for blood lead level were obtained from 40 children. Seventeen (43%) of the children had levels of 0.0 to 0.2 mumol/L (0 to 4 micrograms/dL). Fifteen (38%) had levels of 0.24 to 0.43 mumol/L (5 to 9 micrograms/dL). Eight (20%) children had levels of 0.48 mumol/L (10 micrograms/dL) or greater. The highest value obtained was 0.82 mumol/L (17 micrograms/dL). Seventy-five percent of the children with significantly elevated lead levels resided in suburban communities.
Conclusions: Children seen in a suburban family practice setting are at risk for lead exposure, and screening should be considered by primary care physicians who practice in nonurban settings.
