Description of key information

With high probability the test substance is acutely not harmful to aquatic invertebrates.

Key value for chemical safety assessment

Additional information

To determine the toxicity of ethylene glycol on aquatic invertebrates the study were performed by BASF AG (1998). This study was performed according to OECD TG 202 with Daphnia magna as the test organism. The test concentrations were analytically verified.

The analytical recovery rate was in all analyzed test solutions above 80%.

The 48 -h EC50 for Daphnia was > 100 mg/L (the highest tested concentration, nominal). 

These result is supported with the estimated value, wich was derived from a valid QSAR model (ECOSAR v2.0; BASF SE, 2022). The 48 -h LC50 for the substance was predicted to be 22108 mg/L. The substance was within the applicability domain of the model.

Overall, it can be concluded that with high probability the test substance is acutely not harmful to aquatic invertebrates.
