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.

Biodegradation in water: screening tests

The screening test inherent to the biodegradability of the substance was calculated using the software BIOWIN v4.10. The results indicate that biphenyl-2-ylamine is not expected to be readily biodegradable. The supporting study which is an experimental study also indicates that the chemical is not readily biodegradable in water.


Biodegradation in water and sediment: simulation tests

Half-life period of biphenyl-2-ylamine in water is observed to be 37.5 days (900 hrs.) while in sediment it is 337.5 days (8100 hrs). Based on these half-life values of biphenyl-2-ylamine, it is concluded that the chemical is not persistent in water and sediment.


Biodegradation in soil

EPI Suite has estimated that biphenyl-2-ylamine is expected to be found not predominantly in soil and it’s not persistence estimate is based on its transformation in this medium. Its half-life in soil, 75 days (1800 hrs), does exceeds the threshold of 120 days as per Annex XIII of REACH.

Therefore, biphenyl-2-ylamine is estimated to be not persistent in the soil environment.



The estimated bioconcentration factor (BCF) for biphenyl-2-ylamine is 34.74 L/kg that does not exceed the bioconcentration threshold of 2000. Thus it is concluded that biphenyl-2-ylamine is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
