Validation of a sediment toxicity test with the endobenthic aquatic oligochaete Lumbriculus variegatus by an international ring test

The aim of the project was the validation of a sediment toxicity test with the benthic oligochaete Lumbriculus variegatus by an international ring test. The test method was developed taking into account existing methods. A test protocol was prepared and used to run the test. A total of 14 institutions (governmental agencies, universities, contract laboratories […]

Sediment contact tests as tool for the assessment of sediment quality in rivers and lakes (SeKT)

In current bioassay approaches for assessing sediment toxicity, whole organisms or in vitro systems are exposed to various sediment fractions (e.g. whole sediment, pore water, extracts) considering different exposure scenarios. Whole-sediment exposure protocols represent the most realistic scenario. However, until now the interpretation of sediment contact test results is associated with uncertainties due to the […]
