Additional information

No short-term terrestrial test data is available for alkyl amidoamines/imidazolines. One chronic earthworm test has been performed with 1H-Imidazole-1-ethanamine, 4,5-dihydro-, 2-nortall-oil alkyl derivs. (68442 -97 -7) resulting in a NOEC of 944 mg a.i./kg dw

No effects on mortality, biomass or reproduction of Eisenia fetida were observed during a OECD 222 test under a static exposure for 56 days. Natural soil was used as substrate, and the different concentration of the substance mixed with the substrate. The concentrations applied were 62.5, 125, 250, 500 and 1000 mg/kg soil dry weight. In addition tests using vehicle (quartz sand) control were performed.

The test is valid without restrictions and the results are reliable.

Hence, the NOEC is 944 mg a.i./kg dw soil.
