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.
Drinking Water Impact SURFACE WATER: Water samples collected from rivers in the Tokyo, Japan area, 1974-1978, concn range of pos. samples 0.06-1.9 ug/L . EFFL: Dec. 1974, qualitatively identified in the effluent from a chemical industry in Mt. Vernon, IN .
