Description of key information

A measured BCF is not available for any streams in this category. As the log Kow of some category members is >3 the bioaccumulation endpoint cannot be waived. However, ECHA's Guidance on Information Requirements and Chemical Safety Assessment R7c Endpoint Specific Guidance (2008) indicates that before commissioning a new vertebrate test alternative sources of data on the bioaccumulation potential of a chemical should used.

Representative components on these streams were identified from the compositional data. The representative components are presented in the PBT assessment section of this dossier. The bioaccumulation potential of these substances was compared to the PBT screening criteria for Bioaccumulation in the PBT assessment. For some constituents, experimental data is available or data is reported by the registrants in their dossier. This data shows that none of the various representative components would be expected to be bioaccumulative.

The predicted BCFs for the representative components in this category range from 6 to 752 and the mean is 65.

 

The streams in this category are not considered to be bioaccumulative on the basis of the PBT assessment of representative components.
