Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Principles of method if other than guideline:
- The estimation is based on ECOSAR v1.11. Two models are available, the estimation from the ECOSAR Class (Esters) and the Neutral Organic Structure Analysis Relationship (baseline toxicity).
- Specific details on test material used for the study:
- SMILES: CCCCCCCCCCCCCCCC(=O)(OCC(COC(=O)(CCCCCCCC=CCC=CCCCCC))OC(=O)(CCCCCCCCCCCCCCCCCCC)); MOL FOR: C57 H106 O6; MOL WT : 887.48; Log Kow: 23.506 (EPISuite Kowwin v1.68 Estimate); Wat Sol: 1.619E-020 (mg/L, EPISuite WSKowwin v1.43 Estimate); Calculation is based on the structure and / or properties of oils, menhaden.
- Analytical monitoring:
- not required
- Test type:
- other: calculation
- Total exposure duration:
- 96 h
- Duration:
- 96 h
- Dose descriptor:
- EC50
- Effect conc.:
- 0 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Details on results:
- Asterisk designates: Chemical may not be soluble enough to measure this predicted effect. If the effect level exceeds the water solubility by 10X, typically no effects at saturation (NES) are reported.
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The lowest calculated EC50 to Green Algae for oils, menhaden is 9.6e-014 mg/L.
- Executive summary:
The short-term toxicity to green algae is calculated by ECOSAR v1.11. EC50 value for green algae, 96 h, is 9.6E-14 mg/L derived by calculation from ECOSAR class Esters. The calculated EC50 Neutral Organic Structure Analysis Relationship (baseline toxicity) for green algae is 4.01E-13 mg/L. Since the estimated partition coefficient (LogKow=23.506) is greater than the endpoint specific cut-off (LogKow=6.4), no effects at saturation are expected for this endpoint.
The EPA recommends that empirical measures provide better results. However, empirical studies have not been done, so that we adapt the prediction.
