Additional information

The acute toxicity of BPA-TA to algae was investigated in a study conducted using methodology equivalent to OECD 201 under GLP conditions (Vizon SciTec Inc., 2003).The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).

Selenastrum capricornutum were exposed to adjusted nominal concentrations of 767, 1533, 3066, 6388 and 12777 mg/L under static conditions for 96 hours.

The 96 h EC50, based on mean measured concentrations, was 1713 mg/L (95 % confidence limits 1420 – 2086 mg/L). The NOAEC was <877 mg/L and the LOAEC was 877 mg/L.
