229 g/L

Additional information

The short-term toxicity to aquatic invertebrates is calculated by ECOSAR v1.11. Lowest LC50 values for Daphnid, 48 h, is 229 g/L derived by calculation from ECOSAR class Benzyl Alcohols. The calculated LC50 Neutral Organic Structure Analysis Relationship (baseline toxicity) for Daphnid is 492 g/L. The high values, which exceed the water solubility, reflect the low toxicity. The EPA recommends that empirical measures provide better results. However, empirical studies have not been done, so that we adapt the prediction.
