| Environmental Impact | The primary sources of environmental release of bisphenol A are expected to be effluents
and emissions from its manufacturing facilities and facilities which manufacture epoxy,
polycarbonate, and polysulfone resins. If released to soil bisphenol A is expected to have
moderate to low mobility. This compound may biodegrade under aerobic conditions following
acclimation. If released to acclimated water, biodegradation would be the dominant fate process
(half-life less than or equal to 4 days). In nonacclimated water, bisphenol A may biodegrade after
a sufficient adaptation period, it may adsorb extensively to suspended solids and sediments or it
may photolyze. If released to the atmosphere, bisphenol A is expected to exist almost entirely in
the particulate phase. Bisphenol A in particulate form may be removed from the atmosphere by
dry deposition or photolysis. The small fraction of bisphenol A which would exist in the vapor
phase may react with photochemically generated hydroxyl radicals (half-life 4 hours) or it may
photolyze. Photodegradation products of bisphenol A vapor are phenol, 4-isopropylphenol, and a
semiquinone derivative of bisphenol A. The most probable routes of human exposure to bisphenol
A are inhalation and dermal contact of workers involved in the manufacture, use, transport or
packaging of this compound or use of epoxy powder paints.

| Environmental Fate | TERRESTRIAL FATE: If released to soil, bisphenol A is expected to have moderate to
low mobility because of its water solubility . Based upon aqueous biodegradation tests(1-2),
bisphenol A may biodegrade under aerobic conditions following acclimation. This compound is
not expected to undergo chemical hydrolysis or volatilize significantly from soil surfaces.
AQUATIC FATE: If released to acclimated water, biodegradation would be the dominant fate
process (half-life less than or equal to 4 days) . In nonacclimated waters, bisphenol A
biodegrades , it may adsorb extensively to suspended solids and sediments, or it may photolyze.
This compound is not expected to bioaccumulate significantly in aquatic organisms, volatilize, or
undergo chemical hydrolysis.
ATMOSPHERIC FATE: Based on an estimated vapor pressure of 4X10-8 mm Hg at 25 deg
C(1,SRC), bisphenol A is expected to exist almost entirely in the particulate phase in the
atmosphere . Bisphenol A particles may be removed from the atmosphere by dry deposition or
photolysis. The small fraction of bisphenol A which would exist in the vapor phase may react with
photochemically generated hydroxyl radicals (half-life 4 hours) or it may photolyze.
Photodegradation products of bisphenol A vapor are phenol, 4-isopropylphenol, and a
semiquinone derivative of bisphenol A.
