Analysis of the eight WFD priority PAHs in ground water with added humic acids

IMEP-23 the eight WFD priority PAHs

IMEP-23 is a campaign for laboratories involved in water quality monitoring activities. This interlaboratory comparison deals with the determination of the eight polycyclic aromatic hydrocarbons (PAHs) that are considered priority substances by the EU Water Framework Directive (WFD). These substances are naphthalene, anthracene, fluoranthene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3-cd]pyrene and benzo[ghi]perylene. The sample matrix is water with added humic acids.

Characteristic for this study is its high metrological standard. This may be of particular interest to those who are involved in water quality monitoring activities. The measurement results are evaluated against traceable reference values where possible, and uncertainty statements when provided by participants are included in the evaluation. Participating in IMEP-23 also helps laboratories to benchmark their performance with peers throughout Europe.
