Interlaboratory calibration study in 2011
• present variability in data by comparing results from various passive samplers sent by participating laboratories exposed to water at a single (reference) site
• Target substances:– polar pesticides - 19 participants– Pharmaceuticals – 17 participants– steroid hormones – 15 participants – Triclosan - 8 participants– bisphenol A - 11 participants– PFOA, PFOS - 8 participants– PBDE -16 participants
• 30 participants from commercial, academic and regulatory laboratories

Interlaboratory study DESIGN
• a sampler comparison exercise
• extended to cover individual aspects in the passive sampling process– analytical comparability– comparison with spot sampling

Dissemination of results
3 rounds, May-August 2011
2012 – a workshop will be organised to disseminate results.

Study results
Statistics: 30 participating laboratories from Europe, North America and Australia
292 reference samplers for polar compounds distributed 80 reference samplers for PBDE 268 participant samplers for pesticides and pharmaceuticals285 participant samplers for PFOS, steroids, bisphenol A and triclosan132 participant samplers for PBDE
Total: cca. 1057 samplers were deployed at the reference site and distributed for analysis
The reporting deadline for laboratories has been set to 15th December
A dissemination workshop will be organised in 2012 organised by NORMAN + DG JRC
