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

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

Data-assessment and Reporting results
QUASIMEME Setup of the experiment into a database
Setup of sharepointsites
Instruction of laboratories how to get access to the sharepointsite
Introduce the lab specific contact information into the database.
Do the data-assessment
Produce figures and excel sheets of the assessed data.
Produce z-score lists for each individual laboratory.
Help desk facility with respect to data-transfer

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
