Additional information

An acute toxicity test in Daphnia Magna was conducted (Huntingdon Life Sciences, 2013) to determine the effect of 2-Bromo-3,3,3-trifluoroporopene on aquatic invertebrates following short-term exposure. The study was conducted according to EC test method C2, OECD method 202, and US EPA OPPTS Method 850.1010; the study was performed in compliance with GLP. The test was performed under static conditions; the test vessels were sealed but included a headspace.

In terms of initial measured concentrations, the 48-hour EC50 of 2-bromo-3,3,3- trifluoropropene for the immobilisation of Daphnia magna was 35.8 mg/L (95% confidence limits of 33.1 and 42.9 mg/L) and the ‘no-observed effect concentration’ was 21.9 mg/L.
