EC number: -

The purpose of the study is to evaluate the test substance for its ability to generate toxic effects in Pseudokirchneriella subcapitata during an exposure period of at least 48 and at most 96 hours and, if possible, to determine the NOEC, EC10 and EC50 for both inhibition of growth rate and inhibition of yield.
Due to the very low solubility of this
substance in test medium, concentration levels that might be toxic for
algae could not be reached.
The EC50for both growth rate
inhibition (72h-ERC50) and yield inhibition (72h-EYC50)
was above the solubility limit of A4N3 in test medium.
