Long-term toxicity to fish
Administrative data
Link to relevant study record(s)
- Endpoint:
- long-term toxicity to fish, other
- 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
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The estimation is based on ECOSAR v1.11. Two models are available, the estimation from the Class (esters) and the Baseline Toxicity (neutral organic structure analysis relationship).
- GLP compliance:
- no
- 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
- Dose descriptor:
- other: ChV
- Effect conc.:
- 0 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- not specified
- Remarks on result:
- other: ChV: Chronic toxicity Value
- Details on results:
- ChV: chronic toxicity value; 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 ChV to fish for oils, menhaden is 2.69e-014 mg/L.
- Executive summary:
The long-term toxicity to fish is calculated by ECOSAR v1.11. Lowest ChV value for fish is 2.69E-14 mg/L derived by calculation from ECOSAR class Esters. The calculated ChV Neutral Organic Structure Analysis Relationship (baseline toxicity) for fish is 3.6E-17 mg/L. Since the estimated partition coefficient (LogKow=23.506) is greater than the endpoint specific cut-off (LogKow=8.0), 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.
