A method was developed for the determination of MTMC, MIPC, BPMC, IPMC, furadan, pirimicarb and carbaryl carbamate residues in apples using headspace solid-phase micro-extraction (HS-SPME) coupled with gas chromatography-mass spectrometry. The respective optimal conditions for HS-SPME and GC-MS analysis were determined. All 7 analytes exhibited good linearity over a wide concentration range, with a correlation coefficient ranging between 0.996 and 0.999. The relative standard deviations of precision for 5 replicates were between 3.6% and 8.2%. The limits of detection of the method for a total of 7 analytes were between 0.00016 mg/kg and 0.0019 mg/kg. The method proved to have the advantages of rapidity, sensitivity, accuracy and less reagent consumption and meet the requirements for the determination of carbamate pesticide residues in vegetables and fruits duo to good figures of merit.
