“…Previous studies have been conducted in 1970s which have shown link between intelligence quotient (IQ) and lead. Same results also have been shown in the previous studies [14] .On the basis of numerous studies in v countries it is projected that in the children of preschool years, almost about a quarter to a half of an IQ point is vanished for every increase of 1 µg/dl in the blood lead level .Whole blood levels is as low as 1 young children due to the toxicity of subclinical neurobehavioral [15].A study showed that data collected from 4800 children with age between 6-16 years. These children took part in the Third National Health and Nutrition Examination Survey in the United States, findings showed that there was an inverse relation between the math and reading scores and the blood lead level in the children who have lead level more than 5 µg/dl.…”

“…Blood levels of the antioxidant enzymes SOD and catalase (CAT) has been elevated or suppressed by lead depending mainly on the level and duration of exposure. Higher levels of exposure to Pb in experimental or cross-Volume 11, No 3, May-June2017; http://www.ijt.ir sectional studies are reported to cause increases in the activity of these enzymes as a consequence of elevated reactive oxygen species production [3,[31][32]. However, the activities of GPx, CAT and SOD as major antioxidant enzymes in the erythrocytes significantly crashed usually at chronic exposure with lower amounts of lead [33].…”

“…Elevated blood lead levels (BLL) can adversely affect many organ systems including mental development [5], haemoglobin level [6], kidney function [7], cardiovascular function in adults and reproduction in women [8]. It has been reported that even slightly elevated levels can result in reduced IQ, learning disabilities and behavioural problems [9,10].…”

In Palestine, chronic exposure to lead has not been adequately addressed as a problem for children. To assess the exposure of Palestinian schoolchildren, we surveyed blood lead levels in 3 schools in Nablus city and collected demographic and clinical data. Blood samples were collected from 178 children (140 boys, 38 girls), age range 6-8 years. The overall mean blood lead level was 3.2 (SD 2.4) µg/dL, and 4.5% of children had levels above 10 µg/dL. Blood lead levels were significantly higher among children living in refugee camps near industrial/high traffic regions than among children living in residential areas of the city. Blood lead levels were positively correlated with family size (r = 0.15) and negatively correlated with household area (r = -0.18). Blood lead levels among these Palestinian schoolchildren were higher than those of other countries where leaded gasoline has been banned and seemed to be higher in more economically deprived children. Concentration sanguine de plomb chez des écoliers palestiniens : une étude pilote RÉSUMÉ En Palestine, l'exposition chronique au plomb n'a pas été abordée adéquatement comme un problème chez l'enfant. Pour évaluer l'exposition des écoliers palestiniens, nous avons recherché les taux de plomb sanguins chez des élèves de trois écoles de la ville de Naplouse et avons recueilli les données démographiques et cliniques. Des échantillons de sang ont été recueillis auprès de 178 enfants (140 garçons, 38 filles), âgés de six à huit ans. La concentration de plomb moyenne globale dans le sang était de 3,2 µg/dl (E.T. 2,4), et 4,5 % des enfants présentaient des niveaux supérieurs à 10 µg/dl. Les taux de plomb sanguins étaient nettement plus élevés chez les enfants vivant dans des camps de réfugiés près de zones industrielles/de circulation intense que chez les enfants vivant dans des zones résidentielles de la ville. Les taux de plomb dans le sang étaient positivement corrélés à la taille de la famille (r = 0,15) et négativement corrélés au nombre de mètres carrés du logement familial (r = -0,18). Les taux de plomb dans le sang chez ces écoliers palestiniens étaient supérieurs à ceux d'autres pays où le carburant contenant plomb a été interdit. Ils semblaient aussi supérieurs chez les enfants plus faibles économiquement.
