Description of key information

The acute toxicity of Dodecane-12-lactam, manufacturing of, by-products from, distillation residues was evaluated with Daphnia magna in a study performed in accordance with OECD testing guideline 202 and GLP requirements. EC50-48 h was estimated using measured concentrations as being equal to 33.67 mg/L.

Additional information

The acute toxicity of Dodecane-12-lactam, manufacturing of, by-products from, distillation residues was evaluated with Daphnia magna in a study performed in accordance with OECD testing guideline 202 and GLP requirements.

 

The young daphnids were exposed to nominal test concentrations between 6.25 and 100 mg/L under static conditions during 48 hours. The mean measured concentrations were maintained between 80 and 120 % of nominal. EC50-48 h was estimated using measured concentrations as being equal to 33.67 mg/L.

 

Mortality in control, temperatures, pH range and dissolved oxygen concentration were reported and in agreement with the guideline requirements.
