Key value for chemical safety assessment

Additional information

The test substance is not supposed to be directly applied to sediment. Further, the test substance is readily biodegradable and hence, in case of indirect exposure of sediment, 2,2'-methyliminodiethanol is expected to rapidly degrade. Therefore sediment is not expected to be a compartment of concern. The risk to sediment dwelling organisms is considered to be negligible.

Moreover, sediment toxicity testing is not triggered by the results of the exposure assessment and the risk characterization. The risk-characterisation ratios (RCR) do not indicate a risk for the environment (RCR < 1).
