One long term toxicity test with daphnia has been performed. The 21 d EC10 for reproduction is 270 µg/L based on the nomimal test substance concentration. Corrected for active ingredient which is 94.4% the EC10 is reduced to 254.9 µg/L..
One long term toxicity test with daphnia has been performed. The 21 d
EC10 for reproduction is 270 µg/L based on the nomimal test substance
concentration. Corrected for active ingredient which is 94.4% the EC10
is reduced to 254.9 µg/L. The test was performed with river water as it
is intended to be used in an evaluation of the environmental risks based
on the Bulk approach where it is essential to show that the organisms
were fully exposed to the nominal test concentration. During the test a
decrease of the concentration is observed of about 70%. Imidazolines are
susceptible to hydrolysis and the decrease observed could therefore be
assigned to either hydrolysis or sorption or even both processes.
Imidazolines will however only hydrolyze to an amidoamine which is
relatively resistant to hydrolysis under ambient conditions. As this
hydrolysis will also occur under environmental conditions and
amidoamines have a comparable ecotoxicity as the imidazolines the
Nominal concentration based on active ingredient is considered as the
concentration to be used for the dose effect assesment as no significant
adsorption to glassware was observed and the organisms were thus fully
exposed the the nominal concentration based on active ingredient.
Initially to the imidazoline which might have slowly changed into an
amidoamine during the test. It is considered realistic to relate the
observed effects to the nominal values based on active ingredient.
