  1. Chemical Monitoring On Site (CM Onsite) organised by NORMAN Association and JRC in support of CIS WFDNORMAN Interlaboratory study (ILS) on passive sampling of emerging pollutants Branislav Vrana Water Research Institute, Slovakia branovrana@gmail.com

  2. Activities of NORMAN network in passive sampling 2009-2011 An expert group meeting in 2009 A position paper “Passive sampling of emerging pollutants in the aquatic environment: state of the art and perspectives” in 2010 An interlaboratory calibrationstudy in 2011 www.norman-network.net

  3. 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 Silicone strips CONTACT: branovrana@gmail.com

  4. Interlaboratory studyDESIGN a sampler comparison exercise extended to cover individual aspects in the passive sampling process analytical comparability comparison with spot sampling

  5. Study design 1. Passive samplers from participants Sampler 3 Sampler 3 Sampler 1 Sampler 1 Sampler 2 Sampler 4 Sampler 4 Sampler 2 for selected analyte/analytes Participant 1 Participant 2 Coordinator Participant 3 Sampling site - sampler exposure Participant 4 Report to database ng/sampler of compound A ng/cm2 sampler of compound A ng/L water of compound A calculation procedure for compound A Quasimeme

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

  23. 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 pharmaceuticals 285 participant samplers for PFOS, steroids, bisphenol A and triclosan 132 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
