Description of key information
In a 72-hour algal growth study, cultures of Pseudokirchneriella subcapitata were exposed to 2-Propylheptyl methacrylate under static conditions for in accordance with the OECD 201 guideline. The EC50 was >0.110 mg/L and EC10 > 0.110 mg/L (growth rate).
Key value for chemical safety assessment
Additional information
In a 72-hour algal growth study, cultures of Pseudokirchneriella subcapitata were exposed to 2-Propylheptyl methacrylate at initial measured concentrations of 0 (control), 0.018, 0.026, 0.039, 0.060, 0.11 mg/L under static conditions for in accordance with the OECD 201 guideline. The water pH, temperature and lighting intensity were all maintained within acceptable guideline specifications.
This test was conducted utilizing modified exposure media, closed test system, and reduced inoculation density. The following statistical effect concentrations were obtained after 72 hours EC50 >0.110 mg/L and EC10 >0.110 mg/L (growth rate).
