Additional information

Adsorption/desorption:

The soil sorption organic carbon normalised partition coefficient values (Koc) of Bisphenol A range from 251 to 1507 L/kg, averaging 750 +/- 348 L/kg.

Henry´s Law constant:

At ambient temperature and atmospheric pressure, Bisphenol A is not volatile, with a Henry's law constant calculated to be 3.12E-7 Pa*m3/mol from aqueous solubility and vapour pressure.

Distribution modelling:

Level III Mackay-type modelling shows that nearly all Bisphenol A goes into the water and soil compartments. The exact proportion in each depends on where emissions enter the environment.
