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.
