| Abstract | In support of the implementation of the Water Framework Directive (WFD, 2000/60/EC), three intercomparison exercises were
carried out on European rivers (Po, Danube and Meuse) in order to assess the current state of monitoring methodologies. Laboratories
from European Union (EU) Member States (MSs) were invited to gather at the selected EU river and sample together, each laboratory
with its own method. Participants simultaneously sampled the river water and analyzed according to their protocols.
A selection of priority substances (PSs) [i.e. polybromodiphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs) and
alkyl phenols (APs)] included in Directive 2008/105/EC were analyzed in standard solutions, extracts from river waters and riverwater
samples in order to investigate variabilities in different steps of the analytical process.
Concentrations measured in river samples using WFD-monitoring protocols showed that even some of the most challengingWFD
PSs (e.g., PAHs, PBDEs and APs) can be measured at WFD-relevant concentrations with methods currently applied in MSs, but
variability is still too great and not all laboratories meet required limits of quantification.
Hindrance to the implementation of the monitoring requirements is therefore not the technical feasibility of analysis at these
concentration levels, but rather communication, knowledge exchange and harmonization among the laboratories involved. |
