Description of key information
No toxicity to bacteria was observed with structural analogue substances, the EC0 / EC50 values were, depending on the test conditions, between > 500 and > 10000 mg/L. Thus, concentrations of the test substances were several orders of magnitude above the limit of solubility. In conclusion, no inhibition of biodegradability in STPs or in the environment is expected.
Key value for chemical safety assessment
Additional information
Several tests with activated sludge are available, all of them valid without or with minor restrictions only. The methacrylic acid esters tested had an alcohol moiety chain length of C12 – C22. No toxicity to bacteria was observed, the EC0 / EC50 values were, depending on the test conditions, between > 500 and > 10000 mg/L. Thus, concentrations of the test substances were several orders of magnitude above the limit of solubility. There is, however, no indication that the undissolved test substances interfered with bacterial respiration or the functioning of the test system.
In conclusion, no inhibition of biodegradability in STPs or in the environment is to expect.
