- 32 mg/L
Additional information
The toxicity of the test item to microorganisms was evaluated in an experimental study on 1 g/l aqueous solution of the test item which measured the 5-day Biochemical Oxygen Demand (BOD5) and the bacterial inhibition by the glucose/glutamic acid modification of the BOD5 method. BOD5 and bacterial inhibition were measured at concentrations of 1, 3.2, 10 and 32 mg/l test item without a nitrification inhibitor. A reference substance, glucose/glutamic acid, was tested at approximately a 1:47 dilution of the standard strength solution (150 mg/l of each compound) without nitrification inhibitor.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
