Description of key information

Acute fisch:

In this study C9-11 Methacrylate was found to cause no lethal effects to zebrafish after 96 hours at a nominal loading of 100 mg/L. The LL50 after 96 hours was > 100 mg test item/L. The LL0 and LL100 after 96 hours were >=100 and >100 mg test item/L (nominal test item loading), respectively.

Acute Daphnia:

At the WAF with a nominal loading of 100 mg/L of the test item C9-11 Methacrylate, no effects on Daphnia magna STRAUS were observed.

Aquatic algae:

In this study, the effect values of C9-11 Methacrylate on the growth of the freshwater green alga Pseudokirchneriella subcapitata after 72 hours were determined as follows (based on nominal test

item loadings): The EL50-values for inhibition of growth rate (ErL50) and yield (EyL50) after 72 hours were > 100 mg/L, respectively. The ErL10-value for inhibition of growth rate was > 100 mg/L. The NOEL-values for both inhibition of growth rate and yield after 72 hours were < 100 mg/L, respectively.
