TI  - Application of solid-phase extraction and liquid chromatography-mass spectrometry 
      to the determination of neonicotinoid pesticide residues in fruit and vegetables.

AB  - A rapid and simple method for simultaneous analysis of four neonicotinoid 
      insecticides including acetamiprid, imidacloprid, thiacloprid and thiamethoxam in 
      fruit and vegetable matrices has been developed. For instance, ready-to-use 
      cartridges filled with a macroporous diatomaceous material were used to extract 
      in a single step insecticide residues with dichloromethane from aqueous-acetone 
      extracts of fruits and vegetables. The eluate was evaporated, the residue 
      redissolved with methanol and then analyzed by liquid chromatography-mass 
      spectrometry in the electrospray ionization (ESI) positive mode. Average 
      recoveries of the four pesticides were between 74.5 and 105% at both spiking 
      levels 0.1 and 1.0 mg kg(-1) in peach, pear, courgette, celery and apricot. 
      Relative standard deviations (RSDs) were less than 10% for all of the recovery 
      tests. The calculated limits of quantitation (LOQs) (0.1-0.5 mg kg(-1)) were 
      equal or lower then the maximum residue limits (MRLs) established by European 
      legislation (0.1-0.5 mg kg(-1)). The proposed method is fast, easy to perform and 
      could be utilized for monitoring of pesticides residues.
