The aim of present study was to determine the lead (Pb) distributions in blood and prevalence of elevated Pb exposure among children, age ranged (5–10 years), residing near industrialized region of Hyderabad city, Pakistan. For comparison, biological samples of children of same age group from non-industrial area were also analyzed. The Pb concentration in blood samples was determined by electrothermal atomic absorption spectrometry, prior to microwave assisted acid digestion. The results showed that significantly higher proportion of children living in the vicinity of industrial area, had blood Pb levels (BLL) in the range of 15.4-35.6 μg/dL, and 8.51-16.7 μg/dL for those of non-industrial area. The blood Pb level was higher in boys of both groups as compared to girls of same age group, but the difference was not significant (p=0.178). Negative correlation was observed between BLL and hemoglobin levels (p<0.001), while positive correlation was observed between BLL and age.
