11. Preliminary Conclusions
Homogeneity of spot sampling is a not negligible source of variability
PBDE:
Positive results for standard analysis
Still problems for most of the labs (6// of 10) at EQS level both for extract and river sample analysis
PAH:
Acceptable results for all the samples
No systematic differences among analytical methods
AP:
Stability problems with the commercial standard
Analysis at 1/3 EQS level is still a difficult task

12. Next Actions Within few weeks the final report will be available
We are planning to prepare a conclusive report on the 3 campaigns with final remarks and recommendations for Commission and MS
Next campaign on passive sampling in collaboration with Norman
