- Validity of EC50 model:
1. Defined endpoint: 96-h LC50 for Fish.
2. Unambiguous algorithm: linear regression QSAR; Log 96-h LC50 (mmol/L) = -0.6016 (log Kow) + 0.4479
3. Applicability domain: APPLICATION: This SAR may be used to estimate toxicity for aliphatic amines. LIMITATIONS: For aliphatic amines with log Kow values greater than 7.0, a test duration of greater than 96 hours may be required for proper expression of toxicity. Also, if the toxicity value obtained by the use of this equation exceeds the water solubility of the compound (measured or estimated), mortalities greater than 50% would not be expected in a saturated solution during an exposure period of 96 hours.
4. Statistical characteristics: The LC50 is in millimoles per liter (mM/L); N = 117 + 23; and the Coefficient of Determination (R2) = 0.7609.
Validity of chronic value model:
1. Defined endpoint: chronic value for Fish.
2. Unambiguous algorithm: linear regression QSAR; Log ChV (mmol/L) = -0.5648 (log Kow) - 1.3894
3. Applicability domain: APPLICATION: APPLICATION: This SAR may be used to estimate toxicity for aliphatic amines. LIMITATIONS: If the log Kow value is greater than 8.0, or if the compound is solid and the ChV exceeds the water solubility by 10X, no effects at saturation are predicted.
4. Statistical characteristics: The ChV is in millimoles per liter (mM/L); N = 3; and the Coefficient of Determination (R2) = 0.9979
Adequacy of prediction: the substance falls within the applicability domains described above and therefore the predicted values can be considered reliable. - Validity criteria fulfilled:
- not specified
- Conclusions:
- QSAR predictions were conducted using the latest version of US EPA's ECOSAR (v.1.00, 2009) using input values of -1.89 for log Kow and 1E+006 mg/L for water solubility in the QSAR for aliphatic amines. The model predicted a 96-h LC50 and a chronic value for Fish of 4020.509 mg/L and 49.811 mg/L, respectively. Because the substance falls within the applicability domain of the models these predicted values can be considered reliable.

Additional information
The key study, originally performed by BASF (2000) uses Danio rerio as test species. The acute test performed according to OECD 203 results in an LC50 of 131.2 mg/l after 96 hours for the nominal concentrations of BDMAEE. The same is assumed for the test substance BAEE.
