1st International Medical Conference: Advances in Pediatric Care

Lead and it's compounds are used as additives to several products such as gasoline and paints. Lead has a toxic effect especially on brain and nervous system. Almost no published work has been found providing information about blood lead levels in children of Palestine. And thus the present work was carried out .An improved (ASV/HDME) method for determination of lead in whole blood by anodic strippingvoltametry (ASV) using hanging dropped mercary electrode "HDME" has been developed with a special reagent at An-Najah N, University laboratory. A total of 518 sample from 10th grade students of Jenin district, the samples have been analyzed using the mentioned improved method>The geometric mean of blood levels was 87.75 μg/L, a variation in the geometric mean of blood lead level was noticed with respect to students place of residence;( Camp student 119.43 μg/L), (City students 92.41μg/L), ( Yammon village students 77.65 μg/L). also a variation appeared with respect to27 First International Faculty of Medicine Conference 2008school location, and the highest mean 185.71 μg/L was found in Al-Sallam males school which located near a heavy traffic movement and near an industrial area. In each sample statistic was carried out to seif there was any correlation between blood lead levels and lead risk factors. Factor that found to affect blood lead levels are; gasoline stations, paints workshops, highway' incinerators and quarries. Kidney colic joint pain, R. T. disorder and C. V. disorder appears with increasing blood lead level. Also blood lead level was higher in persons using tea and flour from local mills, and increased in persoms with lower parents education and income level.
