Secondary poisoning

Hazard assessment conclusion:
no potential for bioaccumulation

Additional information

Amides, C16-18(even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl)is expected to be readily biodegradable and expected to also rapidly biodegrade in the terrestrial environment. Therefore, it can reasonably be assumed that there is no significant long term exposure of birds. Based on the available information, the bioaccumulation potential is assessed to be of no significant concern. Therefore secondary poisoning is not considered relevant and thus no PNEC oral for secondary poisoning was derived and no risk assessment on secondary poisoning was performed.

Conclusion on classification

The environmental hazard assessment suggests no evidence to warrant an environmental classification according to EC criteria (67/548/EEC). However according according to CLP criteria (EC 1272/2008)amides, C16-18(even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl)is hazardous to the aquatic environment (long term) with the aquatic chronic category 2 classification.
