AB  - In this study, an innovative rapid detection technology for quickly screening and 
      quantifying organophosphorus pesticides (OPPs) in vegetables was developed based 
      on ambient micro-fabricated glow discharge plasma desorption/ionization mass 
      spectrometry (MFGDP-MS), where Fe(3)O(4)/ZrO(2) synthesized by a one-step 
      coprecipitation was used for enrichment. It can not only effectively enrich OPPs, 
      but can be separated by an external magnetic field, thereby simplifying the 
      traditional steps of centrifugation and cleanup in sample preparation. The 
      introduction of a temperature control system (TCS) can tackle the problem of the 
      low ionization efficiency in MFGDP and expand its application range. Under 
      optimized experimental conditions, the limits of detection (LODs) of the standard 
      solution as low as 0.0068-0.7500 mug L(-1) mm(-2) were achieved, with relative 
      standard deviations (RSDs) being less than 17.8%. Moreover, vegetable extracts 
      were spiked to evaluate the accuracy of the method, and good recoveries 
      (76.9-123.5%) were obtained. Remarkably, it took no more than 7 minutes from 
      sample preparation to testing, resulting in significantly improved ability of the 
      quantitative detection of plentiful samples.
