1,4-bis[(ethenyloxy)methyl]cyclohexane is acutely toxic to aquatic green algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
2.18 mg/L
EC10 or NOEC for freshwater algae:

Additional information

An acute GLP-Test on green algae Pseudokircheriella subcapitata was performed in closed systems according to OECD guideline 201. After 72 hours of exposure an EC50 of 2.18 mg/l and EC10 of 0.86 mg/l was estimated based on growth rate and the mean measured concentration (BASF 2010).
