الملخص

Pesticide residues and contaminants in selected leafy vegetables, namely (Lettuce, garden rocket and salad onion) were monitored at market level in Riyadh City in Saudi Arabia, during the period June to July 2001 Fifteen samples of vegetables from the City vegetable Market of Riyadh were collected and subjected to multi-pesticide residue detection and analysis by gas chromatography with mass spectrometer and electron capture detectors (GC/MS, ECD). Results of sample extracts analysis showed that the two vegetables of: garden rocket and salad onion contain pesticide residues and contaminants which have no Maximum Residue Limits (MRL) prescribed by Codex Alimentarius Commission (CAC) collaborate with World Health and Food and Agriculture Organizations (WHO/FAO). Whereas lettuce vegetable was found free of any identified pesticide residues or contaminants. Garden rocket was shown to contain Dibutyl phthalate (0.04 ppm) - Stearyl chloride (0.02 ppm) Tridecane (0.06 ppm ) - Hexadecane ( 0.07 ppm )- BIS (ethylhexyl) phthalate (0.006 ppm) and Pyridinium, 1- hexylchloride ( 0.01 ppm). The salad onion was found to contain 9-octadecanamide (0.13 ppm) - Tridecane (0.15 ppm) and Tetradecane (0.16 ppm). There are no established MRLs for these pesticides and contaminants detected in garden rocket and salad onion, although when impacts on human health were reviewed some of them were found probably hazardous.
