AB  - Thirteen carbamates were analysed in orange, grape, onion and tomatoes by matrix 
      solid-phase dispersion (MSPD) followed by liquid chromatography-mass spectrometry 
      (LC-MS). Electrospray (ES) and atmospheric pressure chemical ionisation (APCI) 
      were compared and both gave similar results in terms of sensitivity and 
      structural information because at 20 V fragmentor voltages the fragmentation is 
      minimal. The efficiency of different solid-phases (C18, C8, cyano, amine and 
      phenyl) for the MSPD was compared. Mean recoveries using C8 varied from 64 to 
      106% with relative standard deviations of 5-15% in the concentration range of 
      0.01-10 mg kg(-1). Matrix constituents did not interfere significantly with the 
      ionisation process of carbamates. The limits of detection were typically in the 
      0.001-0.01 mg kg(-1) range, which were between 10 and 100 times lower than the 
      maximum residue levels (MRLs) established by the European Union (EU). The method 
      was applied to residue detection in fruit and vegetable samples taken from 
      Valencian markets, in which carbamates were detected at low concentrations.
