Description of key information
Additional information
Bioaccumulation :
Bioaccumulation in Water and Sediment :
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 BCF of 4,4'-dinitrostilbene-2,2'-disulphonic acid in the key study was obtained to be 3.2. Supporting study also indicate the BCF to be 3.162. This low value of BCF of 4,4'-dinitrostilbene-2,2'-disulphonic acid indicates its non bioaccumulative nature as the BCF factor is less than the bio-concentration threshold of 1000.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
