Under the conditions of the study MEA Polyborate 1:1 did not induce acute immobilisation of Daphnia magna at 320 mg a.i./l after 48 hours of exposure (NOEC).
This will be usable for DEA Polyborate by read-across
The 48h-EC50 was 423 mg a.i./l based on nominal concentrations (95% confidence interval between 320 and 560 mg a.i./l).
