AB  - Historical residual of persistent organic pollutants (POPs) in flood sediment 
      from a karst cave were investigated. Fifteen vertical sediment samples were 
      collected from a 6 m-deep flood sediment profile in the Longwang Cave, and the 
      concentrations of organochlorine pesticides (OCPs), polycyclic aromatic 
      hydrocarbons (PAHs) and particle size distribution in the sediments were 
      analysed. The concentrations of OCPs and PAHs varied from 0.85 ng g(-1) to 
      63.1 ng g(-1) (mean 8.11 ng g(-1)) and 5.05 ng g(-1) to 82.6 ng g(-1) (mean 
      13.9 ng g(-1)), respectively; major PAHs in the profile were 2- and 3-ringed PAHs 
      and a few were 5- or 6- ringed PAHs, which indicated less influence from industry 
      but a high impact from the local combustion of coal and biomass; HCHs and DDTs in 
      the profile were historically residual in this region, and HCHs mainly originated 
      from the application of Lindane, while DDTs originated from the application of 
      dicofol and technical DDTs; no significant correlation between the concentrations 
      of OCPs and PAHs and the sedimental particle size in the sediments was found.
