Description of key information

There were no experimental data considering possible bioaccumulation of 2-pyrrolidone in aquatic or terrestrial compartments. Due to the extremely low logPow value of -0.71 there is no necessity to perform any experimental study. Furthermore, an EPI-Win (BCFBAF v3.00) calculation was performed by Chemservice S.A. (2010, updated 2019). The result of the calculation confirms the negligible risk of accumulation in aquatic organisms for 2-pyrrolidone.

Key value for chemical safety assessment

BCF (aquatic species):
3.16 L/kg ww

Additional information

2 -Pyrrolidone has only a very low potential for bioaccumulation in aquatic organisms.
