Description of key information

3-nitrotoluene was found to be inherently biodegradable.


MITI, 1992 (ready biodegradability)


In a modified MITI I test according to OECD guideline 301 C a non adapted mixed microbial inoculum mineralised 2 % of the initial test substance concentration within 14 days.


Pitter, 1976 (inherent biodegradability)


A test on inherent biodegradability was conducted. The test design is comparable to the Zahn-Wellens-test (OECD TG 302 B).
The test substance m-nitrotoluene in a concentration of 200 mg/l COD was the sole source of carbon. Activated sludge from a sewage treatment plant adapted for 20 days to m-nitrotoluene was used as inoculum in a concentration of 100 mg/l dry matter. Based on COD measurement, a removal of 98.5 % within 5 days was obtained.
