Secondary poisoning

Hazard assessment conclusion:
no potential for bioaccumulation

Additional information

C12-C18 TMAC is considered to be readily biodegradable and correspondingly expected to be also rapidly biodegraded in the terrestrial environment. Therefore, it can reasonably be assumed that there is no significant long-term exposure of the substance to soil macro and micro-organisms, terrestrial plants or birds. Furthermore, based on the available information, the bioaccumulation potential is also assessed not to be of 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 of C12 -C18 TMAC justifies R50 classification according toEC criteria (67/548/EEC) and hazardous to the aquatic environment with the aquatic acute and chronic category 1 classification according to CLP criteria (EC 1272/2008). M factors to be applied are 10 for acute and 1 for chronic.
