Additional information

BPA-DA is unstable in water due to hydrolysis. Distribution modelling based on the physico-chemical properties of the hydrolysis product BPA-TA (4,4-Bisphenol A Tetra-Acid, CAS No. 38103-05-8) indicates that sorption to sediment (62 %) and soil (37 %) would be the primary fate of BPA-TA in the environment; limited volatilization (0.1 %) or dissolution in water (1.18 %) would occur. It is important to note, however, that BPA-DA is imported as a monomer in a polymer preparation at a concentration less than 0.1 %. Thus the potential for release to the environment is limited.
