The data set covers the results of a study of 96 samples of peat bog soil from the fall place of the first stage of the Cyclone-3 launch vehicle (launched from Plesetsk Cosmodrome in 2004) contained unburned toxic rocket fuel 1,1-dimethylhydrazine (UDMH) in the European North of Russia. The fall place is located in a peat bog and contains a round central crater (diameter of 6 m) filled with swamp water. There are two data files in this data set. Data file 1 (Excel spreadsheet) presents the concentrations of hydrazines (UDMH; methylhydrazine, MT; and hydrazine, H) in soil samples determined by hydrophilic interaction liquid chromatography with amperometric detection after steam distillation of analytes from alkaline medium. Data file 2 (Excel spreadsheet) presents the concentrations of eight UDMH transformation products (1,1,4,4-tetramethyltetrazene, TMT; formaldehyde N,N-dimethylhydrazone, DMHF; acetaldehyde N,N-dimethylhydrazone, DMHA; furaldehyde N,N-dimethylhydrazone, DMHFur; 1-formyl-2,2-dimethylhydrazine, FADMH; N,N-dimethylformamide, DMF; N-nitrosodimethylamine, NDMA; and 1-methyl-1H-1,2,4-triazole, MT) determined by gas chromatography – tandem mass spectrometry after pressurized liquid extraction of soil samples. The concentration values in both data files were calculated for initial wet soil samples and oven-dried ones using the data on moisture content also presented in the Excel spreadsheets. All concentrations are presented with standard deviation value calculated on the basis of three replicate analyses of each soil sample. Sampling point designations are given in the following format: Cardinal direction (N, S, W, E) – distance from the central crater (m).
