Short-term toxicity to aquatic invertebrates
Administrative data
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- other: Bibliographic source
- Adequacy of study:
- weight of evidence
- Reliability:
- 1 (reliable without restriction)

Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)
- GLP compliance:
- not specified
Test material
- Reference substance name:
- Reference substance 001
- Cas Number:
- 28300-74-5
- Molecular formula:
- C8H4K2O12Sb2 ∙ 3H2O
- Details on test material:
- Trihydrate salt.
Constituent 1
Sampling and analysis
- Analytical monitoring:
- not specified
- Details on sampling:
- S. mixtus was collected from the farm pond in Namyangju city, Korea.
Test solutions
- Vehicle:
- no
- Details on test solutions:
- ATP>= 99.9% and used without further purification. Stock solution of APT was prepared in distilled water. Stock solution was diluted to obtain
suitable concentrations of APT in dechlorinated tap water, embryo rearing solution, moderately hard water (MHW) medium of USEPA
(2002), and algal medium for fish, fertilized eggs, planktonic crustacea, and green algae, respectively.
Test organisms
- Test organisms (species):
- other: Simocephalus mixtus
Study design
- Test type:
- not specified
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 24 h
- Remarks on exposure duration:
- the 48 h-LC50 value was not calculated in the present study. S. mixtus seems to be vulnerable to starvation, and exposure duration less than 48 h may be appropiate for the acute toxicity test.
Test conditions
- Hardness:
- moderately hard water (MHW)
- Test temperature:
- at 21 and 24 ºC
- Details on test conditions:
- Ten milliliters of MHW medium was placed in 35-mL flat-bottomed glass vial. Each test unit contained five neonates (less than 24 h), and test was done with three replicates. Toxicity endpoint selected for S. mixtus was heart beating under microscope because this species tends to stay at the surface of test unit and its movement is not active enough to measure the conventional immobilization.
- Reference substance (positive control):
- no

Applicant's summary and conclusion
- Conclusions:
- The 24-h LC50 value of antimony for S. mixtus was determined to be 4.92 mg/ L.
