EC number: 267-956-0
CAS number: 67953-76-8
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.
