Analysis of BHC migration characteristic in typical vadose zone
The BHC has long-time residual property, bio-accumulation, semi-volatilization, and highly toxic. The BHC has threatened the human health and ecology environment for utilization extensively. Using soil column experiment, the BHC and isomeride migration characteristics in vadose zone was studied. The results showed that BHC migration speed was quicker in fine-sand and the migration speed was slowest in loess. The leaching concentration of γ-BHC was higher than the leaching concentration of α-BHC and β-BHC. But the concentration of γ-BHC could not reach easily dynamic balance. The BHC was priority desorption and released in loess. The study could provide scientific basis for control agriculture contaminated and ensure drinking safety in arid and semi-arid region.
