- Sediment samples cover a wide range of naturally contaminated sandy and silty sediments from open sea, estuaries, rivers an harbor locations.
- Sediments are dried and milled and sieved to < 0.5 mm.
- Sediments are packed in glass bottles (metals: 20 gram; others: 50 gram).
- Dried sediment samples are stable over a number of years when stored at room temperature (except organotins: -20°C).
- You use your normal validated methods and procedures to analyze the test materials.
- New determinands can be added to these programs on request.
- Reports contain all data reported under strict confidentiality, including Z-score plots and method information of methods used.
