Abstract: This paper presents a detection of pesticide residues and additives on imported fruits (Strawberry, Grapes, peaches and apples) using acetonitrile extraction method to determine the residual concentration during seasonal growth until it reaches the consumer. Extraction and purification processes conducted for crops in postgraduate Labs Faculty of Agriculture University of Baghdad. Different fresh fruits and vegetables includes, Egyptian strawberries, African grapes, peaches, American Apple, potato, Iranian tomato, cucumber, Iranian red pepper and Turkish potatoes and cucumber were tested and analyzed using Gas Chromatography/Mass Spectroscopy (GC/M.S).QuEchERS method has been applied for extraction pesticide residues from targeted Vegetable and fruits.The (GC/M.S) has been carried out for distinguish the Vegetable and fruits. Different factors were studied, retention time, elution time, relative abundance and molecular weight. The results showed that the pesticides with low molecular weight were eluted before the high molecular weight pesticides residues of pesticides. Different types of Pesticides were identified, pheromones, organic acids and solvents and anti-fungal to develop a comprehensive intervention measures and to reduce the potential health risk to consumers.
