Description of key information

The aerobic degradation of N,N DIETHYLHYDROXYLAMINE has been examinated during 28 days according to OECD TG 301F and under GLP requirements (Study report, 2011). Under the test conditions, the percentage of biodegradation of DEHA reached 11 % of the ThOD at the end of the test. Validity criteria were fulfilled. The test substance did not inhibit the micro-organisms as shown by the toxicity control flask where biodegradation percentage is 46% higher than 25% within 14 days. According to OECD guideline 301F, DEHA is not readily biodegradable. Since (i) the PEC/PNEC ratio for water, soil and sediment obtained in the exposure are below 1 and (ii) the substance is not PBT/vPvB, no further tests have been proposed to evaluate the degradation of DEHA.
