This news update on EU research centre developing water reference materials is brought to you by



Scientists from the European Commission’s Joint Research Centre (JRC) have developed concepts for the preparation of three model surface-water reference materials (RMs).


The different reference samples contain:


    • eight polycyclic aromatic hydrocarbons (PAHs);


    • six polybrominated diphenyl ethers (PBDEs); and


    • tributyltin in trace amounts.



These will be used to ensure the accuracy of analytical results in checking water quality in the EU.


The JRC, which worked with scientists from other research organisations, says the RMs will “provide quality to the analytical data of EU member states and support the implementation of the water framework Directive (WFD) … and the environmental quality standards Directive.”
