Environmental Impact Ethyl acetate is emitted to the air and discharged into wastewater during its production and use as an industrial solvent and in organic synthesis. It is also released into the air during the formation of whiskey and beer. If released into water ethyl acetate will be lost primarily by evaporation (half-life 10 hr in a typical river) and biodegradation. While ethyl acetate is readily biodegraded in most aquatic tests, the rate in natural waters is unknown. Bioconcentration in fish will be insignificant. If released on land, ethyl acetate will partially evaporate and partially leach into the ground. Biodegradation will probably occur both in soil and groundwater, however, experimental data are lacking. In the atmosphere, ethyl acetate will react with photochemically produced hydroxyl radicals (half-life 8.3 days). A few percent an hour will disappear under photochemical smog situations. Humans will be exposed to ethyl acetate in the workplace, by ingesting certain food items (eg beer) of which it is a natural component, and while using consumer products such as airplane dope and nailpolish remover.
Environmental Fate TERRESTRIAL FATE: If released on land, ethyl acetate will be lost by evaporation and leaching into groundwater. Biodegradation should also occur because it is readily biodegradable in both aerobic and anaerobic systems, but rates for these processes in natural systems are not available. AQUATIC FATE: If released in water, ethyl acetate will primarily be lost by volatilization (half-life 10 hr from a typical river). Biodegradation should also occur, but rates of biodegradation relevant to natural waters are lacking. Ethyl acetate would not be expected to adsorb to sediment or particulate matter. ATMOSPHERIC FATE: Ethyl acetate will react with photochemically produced hydroxyl radicals (clean atmosphere half-life 8.3 days; moderately polluted half-life 2.1 days). Under photochemical smog conditions 1.9-3.4% of the ethyl acetate is lost per hour.
Drinking Water Impact DRINKING WATER: Detected, not quantified in 3 New Orleans drinking water plants . Detected in drinking water-no levels given . GROUND WATER: Not detected in aquifer polluted by a paint factory even though ethyl acetate was stored in buried tanks that leaked . SURFACE WATER: USA-14 Heavily industrialized river basins in USA (204 sites)-only 1 site (Delaware River Basin) positive-1 ppb . Hayashida River in Tatsumo City, Japan (site of leather industry) 585 ppb . EFFL: Oil refinery final effluent-detected, not quantified . Detected, not quantified in effluent from sewage treatment plants . Effluent gas from the metal painting factory and from the lumber painting factory contained ethyl acetate.
