The Centers for Disease Control (CDC) have recently lowered the acceptable blood lead concentration in young children from <=25 to <=10 mug/dl (<=1.21 to <=0.48 mumol/L).
The incidence of lead toxicity with respect to geographical areas and socioeconomic status has not yet been defined.
We evaluated the incidence of increased lead concentration in inner-city, suburban, and rural children aged 9 months to 3 years.
Seven hundred eighty of the 4, 196 studied inner-city samples (18.6%) had lead concentrations >=10 mug/dl (0.48 mumol/L), of which only 71 (1.6%) had lead values >=25 mug/dl (1.21 mumol/L).
Only 5 of the 212 studied children (2.4%) from suburbia and 7 of the 120 children (5.8%) from rural communities had blood lead concentrations >=10 mug/dl (0.48 mumol/L).
