Results: 4-Nonylphenols Analytical Methods: HPLC-MS-MS HPLC-FLD GC-MS Legend: LOD value EQS = 300 ng/l

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

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
