Description of key information

One key study conducted according to GLP and OECD 202.

The acute toxicity of Glycyl to Daphnia magna was determined at approximately 20°C in a 48 -hour static (without renewal of the test media) definitive test.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
20.4 mg/L

Additional information

Based on the nominal exposure concentrations of Glycyl the 24 hour EC50 value was outside the experimental range, therefore the EC50 is greater than >100 mg/L. The 48 hour EC50 value was determined as 20.4 mg/L, with 95 % confidence intervals of 16.4 to 24.8 mg/L. The corresponding no observed effect concentration was observed to be 6.3 mg/L. The lowest nominal Glycyl concentration causing 100 % immobility was 50 mg/L
