Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Biodegradation in water (screening tests)
The MITI List (1986) classifies 2-nitrotoluene as non readily biodegradable. Same conclusions can be extracted from other MITI assay (1992) after a period of 14-d in which a biodegradation of 0.5% of BOD was measured after mixing 100 mg of substance plus 30 mg/l of sludge.
Biodegradation in soil
If released to soil, 2-nitrotoluene may be resistant to oxidation and chemical hydrolysis. According to equilibrium partitioning equations, degradation half-life for (bulk) soil, partly based on Kpsoil is followed. Measured Kpsoil values are preferred, but as not available, a calculated Kpsoil = 4.19 l/kg for 2 -nitrotoluene will be used for estimations. And so, according to the Technical Guidance Document, the half-life for the soil compartment will be assumed to be 300 days (EU risk assessment).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
