Description of key information

Additional information

All key studies regarding acute toxicity to fish, daphnids and green algae indicate the low hazard potential of Imidazole as it is acutely not harmful to aquatic organisms with EC50/LC50 values above 100 mg/l. The lowest EC50/LC50 of 133 mg/l derived from the acute test on algae provides the value for the PNEC calculation.
