AB  - Lindane is a broad-spectrum organochlorine insecticide which has been included in 
      the persistent organic pollutants (POPs) list together with its two 
      hexachlorocyclohexane (HCH) isomers. Due to its continuous use in the past 
      decades, the environmental impacts of HCHs are still severe now. Therefore, in 
      the present study, dielectric barrier discharge (DBD) plasma was used as an 
      advanced oxidation process for the destruction of HCHs in water. The result 
      indicated that in air-DBD system, over 95.4% of the initial 5 mg L(-1) lindane 
      was degraded within 60 min. Moreover, DBD plasma displayed high degradation 
      efficiencies of other HCH isomers including alpha, beta, and delta-HCH. Electron spin 
      resonance spectra, scavenging experiments and theoretical calculations revealed 
      that the synergistic effects of various reactive species were the main reason for 
      the high efficiency of DBD plasma. For instance, both hydroxyl radicals (*OH) and 
      electrons (e(-)) could initiate the degradation of HCHs, while other reactive 
      species such as (1)O(2) and ONOOH played important roles in the decomposition of 
      intermediates. Therefore, the present study not only provided an effective 
      approach for the treatment of HCHs, but also revealed the underlying mechanism 
      based on in-depth experimental investigation and theoretical calculation.
