Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

BIOACCUMULATION AT 0.06 mg/l NOMINAL TEST CONCENTRATION: A mean fish concentration of 4.1 mg/kg, equivalent to BCF = 71,  was determined for non-edible tissues, although no meaningful trends in bioaccumulation were observed at 7 sampling points over the exposure period. 

Analysis of the gut, faeces and visceral tissues at Day 42 showed that 94% of residues were present in faecal matter, 1% in the gut and 5% in the remaining visceral tissues, indicating that the substance was ingested and eliminated with very little accumulation.  

Expressed on a whole-body basis, the mean fish concentration was < 0.41 mg/kg, equivalent to BCF < 7.  

BIOACCUMULATION AT 0.6 mg/l NOMINAL TEST CONCENTRATION: A similar pattern to the lower test concentration was observed. 

The mean fish concentration determined for non-edible tissues, equivalent to BCF = 31.  Analysis on Day 42 showed 83% in faecal matter, 2% in the gut and 15% in the remaining visceral tissues.  

Expressed on a whole-body basis, the mean fish concentration was < 1.0 mg/kg, equivalent to BCF < 2.

Key value for chemical safety assessment
