A semi-field test was conducted to assess the risk of exposure to fufenozide in a ditch and pond adjacent to an agricultural area. To support the investigation, a fast, highly selective, and sensitive method was developed to determine the residue of fufenozide in water, sediment, and soil through high performance liquid chromatography- tandem mass spectrometry. The recoveries were in the acceptable range of 85.6% to 99.3% in the three matrices, with the associated relative standard deviations at 1.2% to 7.8%. The results indicate that the surface water-sediment system could be exposed to fufenozide through runoff after application, which dissipated rapidly in the aquatic ecosystem. The toxicity exposure ratio showed no risk of fufenozide exposure to the fish in the aquatic ecosystem close to the agriculture field.
