摘要：This study was conducted to assess the presence of organochlorines insecticide residues in some common foods from El-Hosh Town community, South Gezira. 48 samples (16 tomatoes, 16 meats and 16 eggs) were randomly collected during the period December 2007 to August 2008. Pesticide residues were determined by gas chromatograph with electron-capture detector (GC-ECD) after dichloromethane extraction and cleanup on Silica gel phase cartridges. The results revealed that, only DDE was detected. All food samples were free of organochlorine pesticides in the four seasons of the years except for two meat samples in spring season. Concentrations of these samples were 1.102 to 0.811 ppm. These findings suggest that, a restricted and controlled use of such persistent pesticides may be useful for decreasing their contamination levels in different food items, therefore, the monitored varieties of food are safe to people's health. This study recommended continuous monitoring of persistent organochlorine pesticides in food in order to safeguard human health and mark their decline with time after the restriction of their usage.
