AB  - Quantification of unsymmetrical dimethylhydrazine transformation products in 
      solid samples is an important stage in monitoring of environmental pollution 
      caused by heavy rockets launches. The new method for simultaneous quantification 
      of unsymmetrical dimethylhydrazine transformation products in sand samples using 
      vacuum-assisted headspace solid-phase microextraction without addition of water 
      followed by gas chromatography-mass spectrometry is proposed. Decreasing air 
      evacuation time from 120 to 20 s at 23  degrees C resulted in increased responses of 
      analytes by 25-46% and allowed obtaining similar responses as after evacuation at 
      -30  degrees C. The best combination of responses of analytes and their relative standard 
      deviations (RSDs) was achieved after air evacuation of a sample (m = 1.00 g) for 
      20 s at 23  degrees C, incubation for 30 min at 40  degrees C, and 30-min extraction at 40  degrees C by 
      Carboxen/polydimethylsiloxane (Car/PDMS) fiber. The method was validated in terms 
      of linearity (R(2)=0.9912-0.9938), limits of detection (0.035 to 3.6 ng g(-1)), 
      limits of quantification (0.12-12 ng g(-1)), recovery (84-97% with RSDs 1-11%), 
      repeatability (RSDs 3-9%), and reproducibility (RSDs 7-11%). It has a number of 
      major advantages over existing methods based on headspace solid-phase 
      microextraction-lower detection limits, better accuracy and precision at similar 
      or lower cost of sample preparation. The developed method was successfully 
      applied for studying losses of analytes from open vials with model sand spiked 
      with unsymmetrical dimethylhydrazine transformation products. It can be 
      recommended for analysis of trace concentrations of unsymmetrical 
      dimethylhydrazine transformation products when studying their transformation, 
      migration and distribution in contaminated sand.
