Additional information

The impact of ethylene urea on soil microorganisms was investigated in two several studies. In one test the nitrogen transformation was measured according to OECD 216 (BASF, 1000108, 2001) and in the other test the carbon transformation was measured according to OECD 217 (BASF, 1000910, 2001). Ethylene urea caused no short-term or long-term effects (< +/- 25% deviation from the control value) on the nitrogen and the carbon transformation.
