1. Agenda Item 7: Review of the list of priority substances (Decision 2455/2001/EC):
(a) Overview of the database and the comments received
Database content
WG-E(4) The central database and associated data treatment
B.FRIBOURG-BLANC, IOW

2. Overall situation Almost all countries provided data:
Many thanks to all data providers…

3. Preliminary data treatment
Only datasets for surface water
River, Lake, Transitional, Coastal, Marine
Elimination of :
data measured before year 2000
non relevant parameters (e.g. P(tot), Nitrates, etc.)
datasets for which neither LOD or LOQ was provided
Insufficient precision of matrix or fraction (all ”other”)
Correction
With MS of missing LoD/LoQ, fraction, inconsistencies…
Internally for missing CAS N°, wrong names, doublets
Harmonisation of the measurement units
Water: µg/l, Sediment: µg/kg dw, Biota: µg/kg ww

4. Summary situation: database content (28 Feb 08)
Surface water
24 Member States + CH and NO
stations
5 water body types
sampling
analysis
937 substances

5. Stations 5 Water Body Types (N° of stations): River: 16 575
Lake: 1 214
Transitional: 868
Coastal: 1 383
Marine: 41

6. Number of analysis

7. Apportionment of analysis
LoD
….and/or
LoQ are provided
26% analysis where the substance is not detected
58% analysis where the substance is detected
16% analysis where the substance is quantified

8. EU relevance of substances

9. Substances analysed in 16 countries or more

10. Matrices and fractions (5 068 940 analysis)

11. Conclusions and perspectives
The central database :
A centralised dataset
The cornerstone for the definition of a manageable list of substances presented with the prioritisation process
The first building block to apply the monitoring-based prioritisation method
A living system that will be transferred to WISE and the EEA
New treatments needed: by RBD, validity criteria?

12. Thanks for your attention…
