AB  - Butralin is widely used to control single-leaf weeds and some dicotyledons. The 
      application of butralin in the environment may cause residue beyond regulation 
      criteria and residual toxicity. Therefore, it is important to detect and 
      supervise the dissipation behavior of butralin in edible raw food and in the 
      environment. The aim of this study was to monitor butralin in peanuts and soil 
      under farmland conditions and examine the likely dietary risk assessment of 
      butralin for Chinese people on the basis of residual concentrations. A method for 
      the analysis of butralin residue and its dissipation in peanut plants and soil 
      under field conditions was investigated. The results show that an analytical 
      method for the quantization of butralin in peanuts and soil utilizing gas 
      chromatography with electron capture detection (GC-ECD) was developed. Standard 
      recovery experiments using three different butralin spiking levels of 0.01, 0.1, 
      and 1.0 mg kg(-1) in different samples (i.e., peanut kernels, shell, seedling, 
      stalk, and soil) were conducted. The recoveries of butralin from all matrices 
      ranged from 86 to 108% with relative standard deviations from 3 to 6% (n = 5). 
      The limit of quantification (LOQ) of the method was 0.01 mg kg(-1). After storage 
      at - 20  degrees C for 365 days, the degradation rate of residues of butralin in peanut 
      kernels was less than 30%, which met the storage stability test criteria for 
      pesticide residues in stored commodities of plant origin. The dissipation 
      half-lives of butralin ranged from 4.2 to 6.6 days and 4.6 to 6.6 days in peanut 
      seedlings and soil, respectively, in farmland ecosystems. At the normal harvest 
      time, the final residue concentrations of butralin in peanuts and soil were all 
      below the LOQ. The final total risk quotient (RQ) values were much lower than 
      RQ = 100%, which indicated that the long-run fitness risk associated with 
      butralin residue in different groups of registered crops is correspondingly low 
      for people in China. The current research results could offer guidance for the 
      rational use of butralin and provide data support for the building of maximum 
      residue limits (MRLs) in China.
