Description of key information

Weight of evidence apperoach was used for estimation the short term toxicity of cardanol to aquatic invertebrates. Cardanol had an LC50 of 1.59 mg/L and 0.42 mg/L after 24 and 48 hr exposures respectively as pr the experimental results.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0.42 mg/L
