Four short-term toxicity to aquatic invertebrates studies are available for the alkyl amidoamines/imidazolines. Three of these tests were performed without chemical analyses due to the absence of the suitable analytical method at the time these tests were performed. Due to the problems expected to produce stable test solutions the reliability of these results is seriously questioned. Based on this limited reliability of these studies it was decided to perform in addition to the study from Gancet (2009) a number of higher tier chronic invertebrate studies. The result of the study from Gancet is considered here as most reliable end point. The 21d EC50 values can be used as a worst-case as acute endpoints.
for the acute fish studies, most of the short-term daphnia tests were
conducted in a period when no reliable specific method of analyses was
available. Hence, most of the tests were considered to be valid with
key study is the most recent study from Gancet (2009). No significant
difference in toxicity in the refined test with river water has been
observed between the different amidoamine/imidazoline products. In
addition to the available acute
studies it was decided to perform a number of higher tier chronic
invertebrate studies as the substances are poorly soluble in water and
exposure in most acute tests was not quantified. The 21d EC50 values
should be used as short term endpoints as a worst-case.
