Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
short-term toxicity to fish
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1994
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Reliability rating was 1 because study was performed under GLP and followed OECD 203/EU Method C.1 test guidelines.
Qualifier:
according to guideline
Guideline:
OECD Guideline 203 (Fish, Acute Toxicity Test)
Deviations:
no
GLP compliance:
yes
Analytical monitoring:
yes
Vehicle:
no
Test organisms (species):
Oncorhynchus mykiss (previous name: Salmo gairdneri)
Test type:
static
Water media type:
freshwater
Limit test:
no
Total exposure duration:
96 h
Remarks on exposure duration:
oil-in-water dispersion
Duration:
96 h
Dose descriptor:
LL50
Effect conc.:
> 5 008 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat.
Remarks:
nominal loading
Basis for effect:
mortality (fish)
Duration:
94 h
Dose descriptor:
other: NOEL
Effect conc.:
> 5 008 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat.
Remarks:
nominal loading
Basis for effect:
mortality (fish)
Sublethal observations / clinical signs:

No mortality was observed in the fish at any of the exposure concentrations including the highest load of 5008 mg/L (OWD). The 96 hr LL50 value was determined to be > 5008 mg/L (loading OWD) and the 96 hr NOEL was > 5008 mg/L based on no mortality.

Validity criteria fulfilled:
yes
Conclusions:
The 96-hr LL50 was >5008 mg/L and 96-hr NOEL was >5008 mg/L. No mortality was observed in the fish at any of the exposure concentrations including the highest loading conc of 5008 mg/L. Hence, these data indicate that the test material would not be expected to cause acute toxicity in fish at its water saturation level or at its maximal water solubility limit.
Executive summary:

The test material produced no mortality in rainbow trout at any of the exposure concentrations including the highest load of 5008 mg/L (OWD). The 96 hr LL50 value was determined to be > 5008 mg/L (loading OWD) and the 96 hr NOEL was > 5008 mg/L based on no mortality.  Overall, the test material is not expected to be acutely toxic to rainbow trout fish at its maximal water solubility.

Description of key information

The test material produced no mortality in rainbow trout at any of the exposure concentrations including the highest load of 5008 mg/L (OWD). The 96 hr LL50 value was determined to be > 5008 mg/L (loading OWD) and the 96 hr NOEL was > 5008 mg/L based on no mortality. Overall, the test material is not expected to be acutely toxic to rainbow trout fish at its maximal water solubility.

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:

Additional information

The 96-hr LL50 was >5008 mg/L and 96-hr NOEL was >5008 mg/L. No mortality was observed in the fish at any of the exposure concentrations including the highest loading conc of 5008 mg/L. Hence, these data indicate that the test material would not be expected to cause acute toxicity in fish at its water saturation level or at its maximal water solubility limit.
