Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 201 (Alga, Growth Inhibition Test)
- Version / remarks:
- 1984
- Deviations:
- not specified
- GLP compliance:
- yes
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 72 h
- Nominal and measured concentrations:
- Test concentrations consisted of a control series and an additive control series (HCO-40, 100 mg/L). A limit test was conducted at the highest dispersion concentration of 100.0 mg/L. Concentrations were measure using HPLC upon start and completion of exposure.

- Duration:
- 72 h
- Dose descriptor:
- EC50
- Effect conc.:
- >= 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- growth rate
- Key result
- Duration:
- 72 h
- Dose descriptor:
- NOEC
- Effect conc.:
- >= 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- growth rate
- Validity criteria fulfilled:
- yes
- Conclusions:
- The test substance did not cause a reduction of growth in a series of algal cultures (test units) exposed to the test item for 72 h. The 72-h NOEC and the 72-h EC50 were each reported as ≥ 100 mg/L as determined by comparison of areas in growth curves. The 24-h to 48-h NOEC and the 72-h EC50 were each reported as ≥ 100 mg/L as determined by comparison of growth rates.

Description of key information
The test substance (TOTM, an analogue substance through read-across) did not cause a reduction of growth in a series of algal cultures (test units) exposed to the test item for 72 h. The 72-h NOEC and the 72-h EC50 were each reprted as ≥ 100 mg/L as determined by comparison of areas in growth curves. The 24-h to 48-h NOEC and the 72-h EC50 were each reported as ≥100 mg/L as determined by comparison of growth rates.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 100 mg/L
