The lowest LC50 recorded in short-term toxicity testing was obtained with aquatic algae (72-h EC50= 9.12 mg/L) indicating that aquatic algae should be considered the most (acutely) sensitive trophic level.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
