Additional information

The available data on toxicity of crotonaldehyde to aquatic organisms clearly indicate that fish is the most sensitive species. In an acute toxicity study, the 96 -hour LC50 to Rainbow trout was reported as 0.65 mg/L. In a fish early life stage study, the 41 -day NOEC was 0.0247 mg/L. Data on long-term effects are also available for the algae species Selenastrum capricornutum. Here, a 96 -hour EC50 of < 0.881 mg/L and a 96 -hour NOEC of < 0.385 mg/L are reported. No long-term results are available for aquatic invertebrates. Here, the most sensitive endpoint for acute toxicity was derived from a 48 -hour study conducted with Daphnia magna, reporting an EC50 of 2 mg/L.

A lower toxicity of crotonaldehyde could be shown to microorganisms. In a study conducted with Pseudomonas putida, the 18 -hour EC10 resulted in 10.4 mg/L.
