AB  - Activated carbon (AC) has recently been shown to be effective in sequestering 
      persistent organic pollutants (POPs) from aquatic sediments. Most studies have 
      demonstrated significant reductions of POP concentrations in water and in aquatic 
      organisms; however, limited data exist on the possibility of using AC to 
      immobilize remaining POPs at terrestrial contaminated sites. Under greenhouse 
      conditions, pumpkin ssp cv. Howden) were grown, and red wiggler worms () were 
      exposed to an industrial contaminated soil containing a mixture of 
      polychlorinated biphenyls (PCBs), i.e., Aroclors 1254 and 1260) treated with one 
      of four concentrations of AC (0.2, 0.8, 3.1, and 12.5%) for 2 mo. The addition of 
      AC to contaminated soils virtually eliminated the bioavailability of PCBs to the 
      plant and invertebrate species. There were reductions in PCB concentrations of 
      more than 67% in ssp and 95% in . These data suggest that AC could be included as 
      part of comprehensive site closure strategy at PCB-contaminated sites.
