Action plan for COST Action 636WG 4 Analytical
issues
2
Main objective of COST action 636

• to assess the role of xenobiotics in the urban
  water cycle and to set up strategies for
  minimising their impact on humans and ecosystems
  
• ? need for analytical tools for
• identification and quantification of xenobiotics
  in the urban water cycle
• identification and quantification of their impact
  on humans and ecosystems

3
WG 4 Action plan month 1 6 (I)

• Selection of target compounds (in collaboration
  with other WG)
• Criteria
• Occurrence in the urban water cycle throughout
  Europe
• Occurrence in most of the compartments of the
  urban water cycle in Europe
• Emerging compounds preferred
• Sub-criteria toxicity, persistence,
  bioaccumulation
• Examples
• Pharmaceuticals (X-ray contrast media,
  lipid-regulators, beta-blockers, NSAID,
  antibiotics)
• Biocides (Triclosan, Sea nine, BAC)
• Heavy metals (Cu, Cd, Zn)

WG 4 Action plan month 1 6 (II)

• Selection of target compounds
• Questionnaire A (target compounds, relevant
  matrices)
• Month 1 preparation and sending it out to all
  COST 636 participants
• Month 2 reply of the participants
• Month 3 evaluation of the data
• Questionnaire B (analytical methods)
• Month 4 sending it out to WG 4 participants
• Month 5 reply of the participants
• Month 6 evaluation of the data
• Presentation of results 2nd meeting

5
WG 4 Action plan month 7 12 (I)

• Interlaboratory study
• Selection of compounds and matrices according to
  questionnaire results
• Preconditions
• No CRM available
• No commercial provider
• Preparation of a draft protocol for sampling,
  sample preparation, shipment, storage
• Examples
• Pharmaceuticals (NSAID, sulfonamides)
• Non-agricultural biocides

6
WG 4 Action plan month 7 12 (II)

• Literature survey on analytical techniques for
  target compounds in different matrices
• Tasks will be distributed between WG 4
  participants during month 6 meeting
• Quality control of existing methods described in
  literature
• Identification of knowledge gaps and research
  needs
• Outcome could be published in a review article

7
WG 4 Action plan Future topics

• Advanced analytical technologies (incl.
  biosensors, nanotechnologies, adsorbents)
• Invite company representatives, additional
  experts
• Quality control for research laboratories
• Minimum requirements for publications of
  analytical methods
• Tools for toxicity evaluation, TIE (together with
  WG 3)
• Sampling
• Sum parameters
• Degradation products (together with WG 2)
• Analytical methods for identification of sources
  (together with WG 1)
• Concepts for identification of future emerging
  compounds

8
WG 4 Future meetings

• April 2006 (Lubljana, Karlsruhe)
• Selection of target compounds
• Analytical methods for target compounds in
  different matrices
• Set-up of interlaboratory study
• Start of literature search on analytical methods
  (distribution of tasks between participants)
• September 2006 (Luxembourg)
• Results of interlaboratory exercise
• Results of literature survey
