AB  - The analysis of a wide range of pesticides in wastewaters (WWs) undergoing 
      different treatments (both modern and conventional) has been studied. The need 
      for optimizing specific extraction methods for each WW effluent based on their 
      physico-chemical characteristics has been considered. A distribution study was 
      performed to establish if the filtration step before extraction is a correct 
      procedure since pesticides can be more prone to be in the aqueous or the solid 
      phase, depending on their hydrophobicity. This evaluation demonstrated that 
      pesticides are distributed between the aqueous phase and the suspended 
      particulate matter (SPM; e.g. pyrethroids are only found in the SPM). The 
      proposed methodologies involved the determination of 39 polar and 139 non-polar 
      pesticides using solid-phase extraction (SPE) and pressurized-liquid extraction 
      (PLE) for the extraction of the aqueous phase and the SPM, respectively. Ultra 
      high pressure liquid chromatography and gas chromatography coupled to tandem mass 
      spectrometry (UHPLC-MS/MS, GC-MS/MS) were used in the determination stage. WW 
      samples from four different technologies were evaluated: membrane bioreactor, 
      extended aeration, maturation pond and anaerobic pond. Validation data for the 
      four effluents studied were generated, obtaining adequate precision values 
      (estimated as % relative standard deviation, RSD) in almost all cases (<25%). The 
      methods showed limits of detection at 0.01-0.20mugL(-1) and limits of 
      quantification from 0.02 to 0.50mugL(-1). The proposed methods were applied to the 
      analysis of real samples collected from an experimental WW treatment plant, 
      detecting non-polar and polar pesticides at concentrations in the range 
      0.02-1.94mugL(-1) and 0.02-0.33mugL(-1), respectively.
