Additional information

Results of toxicity tests towards aquatic microorganisms show, that ammonium carbamate is not harmful to bacteria. In a short term respiration test, performed similar to OECD guideline 209, an EC20 of 1000 mg/l within 30 min was determined (BASF AG 1990). This is supported by a single species test, performed according to a German guideline (DIN 38412, part 8) using Pseudomonas putida as test bacterium. This test resulted in an EC10(16h) of 830 mg/l.
