General Information

  • Biota test materials are collected from contaminated waters, seawater and coastal sites in Europe like the North Sea, Baltic Sea and the Mediterranean Sea.
  • Depending on the type of exercise, biota samples are prepared from shellfish 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.

Determinands

The list below shows the typical determinands for the Biota programmes. For a list of determinands which are under the scope of accreditation please check here.
