Reference
Endpoint:
short-term toxicity to fish
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1984
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Justification for type of information:
The main structure of the read-across substance is the same of the CJ304, only the salt form is different. However, this difference does not influence the toxicity of the CJ304. CJ304 contains Li/Na salt form and the read-across substances contains only Na salt. This will not lead to difference on the toxicity results.
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 203 (Fish, Acute Toxicity Test)
Version / remarks:
Comparable to internationally accepted guidelines.
GLP compliance:
no

Details on results:
After 48h: 10/10, 0/10, 0/10 fishes survived at 100 mg/L, 300 mg/L and 1000 mg/L respectively.
After 96h: 10/10, 0/10, 0/10 fishes survived at 100 mg/L, 300 mg/L and 1000 mg/L respectively.
Validity criteria fulfilled:
not specified
Conclusions:
The 96h LC50 of FAT 41001/D in this fish acute toxicity test was determined to be 143.12 mg/L.
Executive summary:

The acute fish toxicity test of FAT 41001/D was performed using a methodology equivalent or similar to OECD Guideline 203. 10 Zebra fish per concentration were exposed to FAT 41001/D for 96 hours at following concentrations: 100, 300 and 1000 mg/L.

After 48h: 10/10, 0/10, 0/10 fishes survived at 100 mg/L, 300 mg/L and 1000 mg/L respectively.

After 96h: 10/10, 0/10, 0/10 fishes survived at 100 mg/L, 300 mg/L and 1000 mg/L respectively.

Based on these findings, the 96h LC50 of FAT 41001/D in this fish acute toxicity test was determined to be 143.12 mg/L.

Summary;

LC0 (48 h) : 100 mg/L

LC50 (48 h) : 181.5 mg/L

LC100 (48 h) : 300 mg/L

LC0 (96 h) : 100 mg/L

LC50 (96 h) : 143.12 mg/L

LC100 (96 h) : 300 mg/L
