General information
- Biota test materials are collected from contaminated waters, seawater and coastal sites in Europe like e.g. the North Sea, Baltic Sea and the Mediterranean Sea.
- Depending on the type of exercise, biota samples are prepared from mussel tissue, fish tissue, fish liver or shrimp.
- Biota samples are either natural contaminated or spiked with a selection of determinands where relevant.
- Biota tissue samples contain ± 50 gram of homogenized tissue.
- Biota samples are autoclaved and have been shown to be stable over a number of years when stored at room temperature.
- Reports contain all data reported under strict confidentiality, including Z-score plots and method information of the methods used.
