AB  - A total of 23 pesticides from different chemical groups in 160 different domestic 
      vegetables collected from four major big supermarkets located in Al-Qassim 
      region, Saudi Arabia, were identified by gas chromatography with mass 
      spectrometry (GC-MS). Residues were found in 89 of the 160 samples and 53 samples 
      were above the maximum residue levels (MRLs). The most frequently found 
      pesticides were carbaryl followed by biphenyl and then carbofuran. Cabbage was 
      the most positive and violated MLRs (16 and 11 samples), followed by carrot and 
      green pepper (12 and 7 samples), cucumber (12 and 6 samples), egg-plant (12 and 5 
      samples), squash (11 and 7 samples), lettuce (11 and 6 samples) and tomato (11 
      and 4 samples). The highest concentrations were found in lettuce (ethiofencarb, 
      7.648), followed by tomato (tolclofos-methyl, 7.312 mg/kg), cabbage 
      (chlropyrifos, 6.207 mg/kg), carrot (heptanophos, 3.267 mg/kg), green pepper 
      (carbaryl, 2.228 mg/kg) and egg-plant (carbaryl, 1.917 mg/kg). These findings 
      pointed to the following recommendation: the need for a monitoring program for 
      pesticide residues in vegetables cultivated under greenhouse conditions at the 
      national level to protect consumers' health.
