Participation in the Sediment Exchange for Tests on Organic Contaminants (SETOC) is open to all laboratories. The normal validated methods and procedures of each laboratory should be used to analyse the test materials. Laboratories are requested to fill in method information codes (MIC) for each determinand. This allows laboratories to review the range and similarity of the methodologies used.

General Information

  • The sample types/matrices are chosen to represent the materials which you normally analyse. There is no spiking or use of artificial samples.
  • The samples are obtained from river beds, lake bottoms and harbours.
  • Sediments are dried and milled and sieved to < 0.5 mm.
  • The homogeneity of each batch of samples is tested on a selection of parameters.
  • The dried sediment samples have been are stable over a number of years when stored at room temperature.
  • You analyze the samples according to your own procedures and for those elements and parameters you are interested in. ·Your results are processed at WEPAL-QUASIMEME and published every three months under confidential code names.
  • The reports contain all data, statistical evaluation including Z-score plots and method information about the method used.
  • Your reports are available within one month after the submission deadline
  • New determinands can be added on request.
