In support of the implementation of the European Water Framework Directive (WFD) the European Commission (EC) Joint Research Centre (JRC) organized a laboratory and sampling intercomparison study for the chemical monitoring of polyaromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), and nonyl- and octylphenol (NP/OP), priority substances of the WFD, in river water. EU Member State laboratories were invited to analyse a standard solution with unknown concentration levels and a river water extract, as well as a real water sample from the River Po (N-Italy). For the standard solution and the river water extract good agreement was achieved for 5 laboratories. Triple quadrupole LC-MS-MS and GC-MS with or without derivatization showed to be well comparable methods for the analysis of NP and OP. Also fluorescence detection can be used to analyze NP/OP, but it is less specific. The results of the River Po water sample showed that some laboratories have problems in analyzing NP at concentration levels below 100 ng/L due to laboratory blank contamination. No plastic materials should be used during extraction and sample preparation.
