title: Lead Assessment in Biological Samples of Children with Different Gastrointestinal Disorders.
abstract: Lead (Pb) levels have been evaluated in the biological samples of children with different gastrointestinal disorders. Blood, scalp hair, and urine samples of children (of age 4-10 years) complaining about different gastrointestinal disorders were analyzed. For comparison, age matched healthy subjects were also included in this study. Biological samples were digested in a microwave oven prior to Pb determination by graphite furnace atomic absorption spectrometry. Significant differences in Pb profile were found between the diseased and referent children. Elevated Pb contents were observed in case of diseased children than WHO permissible limit, while normal results were obtained for healthy referents. The results were compared with those of healthy children having the same age, socioeconomic status, and residential areas.
