The gas chromatography-mass spectrometry (GC-MS) method and high performance liquid chromatogra-phy (HPLC) method were described for determination of fenjuntong in water and three kinds of soils. The residues of fenjuntong were extracted with solvents, utilizing GC-MS and HPLC to determine the extracts. The results showed that the fortified recoveries of the GC-MS method were 92.62%-102.23% with the relative standard deviations (RSD) of 1.14%-14.19%, the linear range of the working curve was 1.0-100.0 mg/L, and the linear correlation coefficient was 0.993 3. The fortified recoveries of the HPLC method were 87.80%-101.03%with the RSD of 0.31%-7.94%, the linear range of the working curve was 0.1-10.0 mg/L, and the linear correlation coefficient was 1.000 0. The study provided effective methods for detection of fenjuntong residues.
