Description of key information

No data are available for long-term toxicity of cyclohexyldimethylamine (DMCHA) to fish. 

Key value for chemical safety assessment

Additional information

 The results from short-term toxicity tests on fish, Daphnia and algae demonstrate that algae are the most sensitive trophic level tested. Therefore, it may be concluded that results from a long-term test in fish would not reveal a greater hazard than already determined by the available data. Therefore, and for reasons of animal welfare, a chronic test on fish is not provided.

Moreover, the chemical safety assessment for Cyclohexyldimethylamine demonstrates that 1) the exposure levels estimated in all relevant scenarios do not exceed the appropriate PNEC, and 2) the likelihood and severity of an event occurring due to the physicochemical properties of the substance in the aquatic environment are negligible; therefore, the criteria for adaptation are met. Specifically, all risk characterization ratios are under 1.0; and there are no physicochemical hazards identified for this substance in the aquatic environment.
