AB  - A methodology is presented for the determination of four pyrethroid (PYR) 
      preservatives in wooden food contact materials (FCMs) using direct analysis in 
      real time (DART) coupled with quadrupole-Orbitrap high-resolution mass 
      spectrometry (Q-Orbitrap HRMS). The sampling mode and critical parameters of the 
      DART-Q-Orbitrap HRMS protocol were systematically investigated. Good linearity 
      was achieved for the four analytes with correlation coefficients all greater than 
      0.99. The limits of detection (LODs) and limits of quantitation (LOQs) of the 
      method were in the range of 0.04-0.20 mg kg(-1) and 0.10-0.50 mg kg(-1), 
      respectively. The mean recoveries ranged from 72.1% to 82.7% with relative 
      standard deviations (RSDs) from 5.2% to 11.8% at three spiked levels. The 
      developed method was proved to be suitable for rapid screening of PYRs in complex 
      wooden FCM samples to ensure product safety and consumer health.
