Lead exposure and poisoning is one of the environmental problemsaffecting and threatening humans; specially children, with profoundphysical, psychological and social negative impacts.This study was conducted during January 2005 to January 2007 on310 pupils ranging in age between 6 to 17 years. The pupils belonged to 4primary schools in Taybat Alameda these were Tagwa School for Girlsand Tagwa School for Boys (105 and 60 respectively). These schools liein close proximity to Khartoum North Industrial area. The control groupwere pupils from Tayba School for Girls and Tayba School for Boys(111, 64 respectively). The study assessed the lead levels of the pupils.The possible associated factors including residence, drinking water, food..etc, that affect the lead levels, and the impact of these factors on thechild health, behaviours and academic performance were investigated.A detailed questionnaire was designed and offered to the pupils in thestudy area to collect basic data related to socioeconomic status. This datawas used further in explanation of the blood lead level. Filling of thequestionnaire was performed by their teachers and parents.Different samples of air, water, soil and food items from both areaswere collected randomly and analyzed for lead concentration. The highestlead concentration tends to be in girls (16.163 ppm) than boys (10.003ppm). There were 7 girls and one boy with lead level above theIVpermissible level. All of them were from Tayba area. No pupil fromTagwa area scored blood lead above the permissible level.Pupils with fair academic performance showed higher leadconcentration in blood (3.35 ppm) when compared with those of lowacademic performance. To the age group 10 – 14 years belonged pupilswith the highest amount of lead (2.05 ppm).The pupils whose parents were workers had the highest amount ofblood lead (2.26 2 ppm). Parents with primary education had theirchildren with high amount of blood lead (2.06 ppm). It seems that leadlevels in the pupils blood is inversely related to eating eggs and drinkingmilk (2.49 ppm) and (9.20 ppm) respectively, compared to eatingvegetables, bread and meat.Those who complained from stomach and headache, the highest bloodlead level they had (2.39 ppm) and (0.36 ppm) respectively.Pica behaviour is associated with lead exposure (2.72 ppm). No leadwas detected in air or water samples.The different food samples contained different lead concentrationsranging between (0.083- 0.0918ppm)in Tagwa and Tayba arearespectively, which is below the permissible level of the milk samplesfound to contain amount of lead with mean (0.236 ppm).The lead concentration in the soil samples was not above the levelexcept one case in Tagwa area (249.4 ppm).
