Description of key information

Additional information

The substance is registered as TII and therefore an environmental fate assessment is not required.

However, with regard to degradation the following can be concluded:

Nitrilotriacetonitrile is not biodegraded in the prolonged Closed Bottle test. Nitrilotriacetonitrile should therefore not be classified as readily

biodegradable. The lack of biodegradation in the Closed Bottle test does not mean that nitrilotriacetonitrile is persistent in nature because the

stringency of the test procedures could account for the recalcitrance in the Closed Bottle test.

With regard to mobility the following can be conlcuded:

The estimated log Koc values are less than the threshold value of 3, indicating no adsorbing potential for this compound.
