Sammendrag
The 6th intercalibration of invertebrates in the ICP-Water programme had contribution from 6 laboratories. All of the laboratories identified a high portion of the individuals in the testsamples, usually >90% of the total number of species. Short-coming identification were consequently low. Of the identified species only few faults were made and the results were regarded generally as very good and well within the limit of good identification proposed for intercalibration of biological material. The result was suffcient both for stating the acidity index, and for multivariate statistical analyses. Discrepancies between the number of larvae put into the test samples and recorded number demonstrate that contamination of larvae occur either at the laboratory making the samples or at the participating laboratory.
