There are little data of such analyses, which is mainly caused by the low number of analytes covered by the available anal. methods and their complexity. A simple and cost-efficient method for accurate simultaneous determination of seven unsym. dimethylhydrazine transformation products in air using solid-phase microextraction followed by gas chromatog.-mass spectrometry was developed. The method was optimized for air sampling and solid-phase microextraction from 20-mL vials, which allows full automation of anal. The extraction for 5 min by Carboxen\/polydimethylsiloxane fiber from amber vials and desorption for 3 min provided the greatest analytes&#8217; responses, lowest relative standard deviations, linear calibration (R2 \u2265 0.99), and limits of detection from 0.12 to 0.5\u03bcg\/m3. Samples with concentrations 500\u03bcg\/m3 can be stored at 21 \u00b1 1\u00b0 without substantial losses (1-11%) for up to 24 h, while air samples with concentrations 10 and 50\u03bcg\/m3 stored for up to 24 h can be used for accurate quantification of only two and four out of seven analytes, resp. The developed method was successfully tested for the anal. of air above real soil samples contaminated with unsym. dimethylhydrazine rocket fuel.
