AB  - Nonylphenol ethoxylates (NPEOs) have drawn significant attention within the last 
      decade for both scientific and legislative reasons. In Turkey, the Regulation 
      Regarding the Use of Domestic and Urban Sludges on Land states a limit value for 
      the sum of nonylphenol (NP), nonylphenol monoethoxylate (NP1EO) and nonylphenol 
      diethoxylate (NP2EO) as NPE (NPE=NP+NP1EO+NP2EO). Unfortunately a standard method 
      for the determination of these chemicals has not been yet set by the authorities 
      and no data exists about the concentrations of NP and NPEOs in sewage sludge in 
      Turkey. The aim of this study is to propose simple and easily applicable 
      extraction and measurement techniques for 4-n-nonylphenol (4-n-NP), NP, NP1EO and 
      NP2EO in sewage sludge samples and investigate the year round concentrations in a 
      Metropolitan Wastewater Treatment Plant (WWTP) in Turkey. Different extraction 
      techniques and GC/MS methods for sewage sludge were tested. The best extraction 
      method for these compounds was found to be ultrasonication (5 min) using acetone 
      as the solvent with acceptable recovery of analytes suggested by USEPA and other 
      studies. The optimized extraction method showed good repeatability with relative 
      standard deviations (RSDs) less than 6%. The recovery of analytes were within 
      acceptable limits suggested by USEPA and other studies. The limits of detection 
      (LODs) were 6 microg kg(-1) for NP and NP1EO, 12 microg kg(-1) for NP2EO and 0.03 microg 
      kg(-1) for 4-n-NP. The developed method was applied to sewage sludge samples 
      obtained from the Central WWTP in Ankara, Turkey. The sum NPE (NP+NP1EO+NP2EO) 
      was found to be in between 5.5 microg kg(-1) and 19.5 microg kg(-1), values which are in 
      compliance with Turkish and European regulations.
