Sammendrag
The 9th intercalibration of invertebrates in the ICP Waters programme had contribution from 4 laboratories. Most of the laboratories identified a high portion of the individuals in the test samples, usually > 90% of the total number of species, but shortcoming identifications below this limit were also noted. Misidentifications and low % identified were in general made on material coming from regions outside the home region of the laboratory. No faults were recorded on genus level. The quality was sufficient for stating the acidity index. Improvements in taxonomic work were tested among laboratories participating several times. First time participants had a significant lower mean Quality index than second, third or higher times participants.
