Description of key information

Bioaccumulation is the process by which the chemical concentration in an aquatic organism achieves a level that exceeds that in the water, as a result of chemical uptake through all possible routes of exposure. The relationship between bioaccumulation and bio-concentration is that, chemicals that have the potential to bioconcentrate also have the potential to bioaccumulate. Bioaccumulation is closely related to the Bioconcentration factor (BCF). 
The estimated bioconcentration factor (BCF) for sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is 71, which does not exceeds the bioconcentration criteria (BCF=2000). Thus, it is concluded that sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.

By applying weight of evidence approach to the target substance sodium 2-(2-dodecyloxyethoxy) ethyl sulphate,the endpoint value of bioaccumulation was found to vary between BCF = 70.79 to 72.127 in aquatic organisms /fish.Thus it is concluded that the test substance sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
