1 248 mg/L

Additional information

The acute toxicity of BPA-TA to Daphnia magna was investigated in a study conducted using methodology equivalent to OECD 202 under GLP conditions (Vizon SciTec Inc., 2005).The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).

Daphnids were exposed to adjusted nominal concentrations of 78, 156, 312, 624 and 1248 mg/L under semi-static conditions for 96 hours.

After the 96-h exposure, there was one Daphnia (5 %) immobilised at 624 mg/L and 7 Daphnia (35 %) immobilised at 1248 mg/L. Therefore, the 96-h EC50 estimate was >1248 mg/L, based on adjusted nominal concentrations. The NOEC and LOEC were 1248 and >1248 mg/L, respectively.
