TI  - Persistent organic pollutants (POPs) in the sewage treatment plant of 
      Thessaloniki, northern Greece: occurrence and removal.
PG  - 2685-98
AB  - The occurrence and the removal of persistent organic pollutants (POPs) during the 
      conventional activated sludge treatment process were investigated in the 
      wastewater treatment plant of the city of Thessaloniki, northern Greece. POPs of 
      interest were seven polychlorinated biphenyls (PCBs) and 19 organochlorine 
      pesticides. Target compounds were determined at six different points across the 
      treatment system. Most abundant compounds in raw wastewater at all treatment 
      stages were PCB-52, PCB-110, PCB-180 and Heptachlor-exo-epoxide. Quintozene 
      occurred frequently but in relatively low concentrations. Hexachlorocyclohexanes, 
      DDT and its metabolites (DDE, DDD) and Aldrin, Dieldrin, Endrin, Isodrin 
      ("Drins") were found at medium or low frequencies and in concentrations close to 
      their detection limits. Removal percentages throughout the whole treatment 
      process ranged from 65% to 91% for individual POP species. Significant linear 
      relationship was observed between removal efficiency and log Kow for PCBs 
      suggesting that compounds with a strong hydrophobic character are principally 
      removed through sorption to sludge particles and transfer to the sludge 
      processing systems. Total PCBs' concentrations in sewage sludge ranged between 
      185 and 765 ng g(-1) dw being below the EU limit for use of sludge in 
      agriculture.
