Endpoint summary
Administrative data
Description of key information
The substance is classified very toxic to aquatic life based on the following results.
LC₅₀ (96 h), fish (Danio rerio): 1.30 mg/L (measured concentration, OECD 203)
EC₅₀ (48 h), daphnia (Daphnia magna): 1.47 mg/L (measured concentration, OECD 202)
EC₅₀ (48 h), alguae (Pseudokirchneriella subcapitata): 0.34 mg/L (based on growth rate - measured concentration -
OECD 201).
EC₅₀ (48 h), alguae (Pseudokirchneriella subcapitata): 0.31 mg/L (based on yield - measured concentration - OECD
201).
Additional information
Solubility of Myrcene in water
A study was conducted to determine the water
solubility of myrcene according to OECD Guideline 123 using the slow
stirring method.
The water solubility obtained for myrcene is the mean of two independent
determinations at 20°C: 5.06 mg/L.
Available ecotoxicological dataset
A summary of the ecotoxicological dataset available on Myrcene is provided in the table hereafter.
