Toxicity to aquatic algae and cyanobacteria

Description of key information
One key study has been identified as having assessed the short-term toxicity of ethyl methyl carbonate to freshwater green algae (Scenedesmus subspicatus (new name: Desmodesmus subspicatus)) – an OECD 201, GLP-compliant test using and analytically verified test concentrations.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 62 mg/L
- EC10 or NOEC for freshwater algae:
- 62 mg/L
Additional information
In the acute toxicity to aquatic algae test, results of the range-finding study suggested that it was appropriate to only conduct a limit test for the main study. In the main study, no significant algal growth inhibition occurred. Analysis of the test concentrations revealed a significant decline in test concentration and so results were based on time-weighted measured mean concentrations. A 72-h EC50 of >62 mg/l (for both growth rate and biomass) and NOEC of 62 mg/l were determined and these suggest that ethyl methyl carbonate is of low toxicity to freshwater algae.
