The 21-day-chronic toxicity of Bisphenol AF to Daphnia magna was studied under semi-static conditions. Daphnids were exposed to a control, and test chemical at nominal concentrations of 0.11, 0.23, 0.45, 0.90 and 1.8 mg/L. The 21-day NOEC based on mortality was 0.90 mg/L. The 21-day NOEC based on reproductivity was 0.23 mg/L. Production of offsprings in the treated groups indicated that Bisphenol AF had an effect on the reproduction at concentrations greater than 0.23 mg/L. The most sensitive end point was reproductivity (NOEC = 0.23 mg/L).

Applicant's interpretation:
For the husbandry water fleas were kept in 3-L aquariums covered with glass plates (20 daphnids in 2.5 L of Elendt M4 medium) at 21 ± 1 °C in a 16 h light/8 h dark photoperiod. Water fleas were fed daily as follows: four times with green algae D. subspicatus (0.13 mg of C/daphnid), twice per week with Tetramin (20 mg blended in deionized water/aquarium) and once a week with dry yeast (5 mg blended in deionized water/aquarium). Ten replicate vessels (50 mL medium/ medium-test-item) containing 1 daphnid each (Straus 1820 (Clone A)) was used at each concentration and the dilution water control. During testing Daphnia were fed 0.15 mg of C/daphnid. Media was changed three times a week on Monday, Wednesday and Friday. The concentrations tested were 0.11, 0.23, 0.45, 0.90, 1.8 mg/L. The endpoints of 21 d chronic toxicity tests were survival of females, reproduction, i.e., cumulative number of living offspring per surviving female, the average brood size per female, the number of broods per female, days to first brood and body length.
During the test they assessed the stability of BPAF in the Daphnia medium (Elendt M4 medium) and showed it to be stable over 3 days. After dosing, BPAF stayed at 90 % of nominal concentrations, therefore the use of nominal concentrations can be used in line with the guideline. This showed that dosing technique was appropriate as well as the stability of the test item in the test system. Water quality parameters were meausred but not reported. Validity criterion for number of neonates per parent animal in the controls (> 60 per parent require) was met, however whether there was mortality in the controls or not was not reported. Despite this omision the study is well conducted and expected to be reliable.

Additional information
In a single key study by Tisler et al., 2016, a suite of aquatic ecotoxicity tests were conducted to identify hazards to the aquatic environment and conduct a risk assessment using measured concentration of BPAF from the environment to determine a risk characterisation ratio (i.e. predicted exposure concentration (PEC)/predicted no effect concentration (PNEC). Firstly, a suite of low tier aquatic toxicity tests were conducted on V. fischeri (bacteria), Desmodesmus subspicatus (green algae), Daphnia magna (invertebrate) and Danio rerio (fish; common name zebrafish). Based on there results they found daphnids to be the most sensitive trophic level and as such conducted a long-term test using Daphnia magna.
For the husbandry water fleas were kept in 3-L aquariums covered with glass plates (20 daphnids in 2.5 L of Elendt M4 medium) at 21 ± 1 °C in a 16 h light/8 h dark photoperiod. Water fleas were fed daily as follows: four times with green algae D. subspicatus (0.13 mg of C/daphnid), twice per week with Tetramin (20 mg blended in deionized water/aquarium) and once a week with dry yeast (5 mg blended in deionized water/aquarium). Ten replicate vessels (50 mL medium/ medium-test-item) containing 1 daphnid each (Straus 1820 (Clone A)) was used at each concentration and the dilution water control. During testing Daphnia were fed 0.15 mg of C/daphnid. Media was changed three times a week on Monday, Wednesday and Friday. The concentrations tested were 0.11, 0.23, 0.45, 0.90, 1.8 mg/L. The endpoints of 21 d chronic toxicity tests were survival of females, reproduction, i.e., cumulative number of living offspring per surviving female, the average brood size per female, the number of broods per female, days to first brood and body length.
During the test they assessed the stability of BPAF in the Daphnia medium (Elendt M4 medium) and showed it to be stable over 3 days. After dosing, BPAF stayed at 90 % of nominal concentrations, therefore the use of nominal concentrations can be used in line with the guideline. This showed that dosing technique was appropriate as well as the stability of the test item in the test system. Water quality parameters were meausred but not reported. Validity criterion for number of neonates per parent animal in the controls (> 60 per parent require) was me, however whether there was mortality in the controls or not was not. Despite this omision the study is well conducted and expected to be reliable.
The lowest NOEC for reproduction will be used in the chemical safety assessment. The NOEC was 0.23 mg/L.
