Description of key information

Acute toxic to fish: LC50 (96h) = 6.18 mg/L

Key value for chemical safety assessment

Additional information

The acute data on formaldehyde toxicity to fish are similar and do not vary to a great extent.The most sensitive species is the striped bass (Morone saxatilis) for wich a LC50 (96 h) = 6.18 mg/L is reported (Reardon, 1990). A lower LC50-value of 1.98 mg/L was obtained in the same study. However, due to additional hypoosmotic stress this value is considered not relevant.
