ABSTRACT
2-Ethylhexyl acetate, which is used as a solvent, may be released in fugitive emissions during its manufacture, formulation, or use in commercial products. If released to soil, 2-ethylhexyl acetate is expected to display slight mobility. Volatilization is expected to occur from both moist and dry soils. Hydrolysis of 2-ethylhexyl acetate in soil is not expected to be a significant process except in highly basic soils with a pH >9. If released to water, 2-ethylhexyl acetate is expected to rapidly volatilize to the atmosphere. The half-life for volatilization from a model river is 4.2 h. 2-Ethylhexyl acetate may adsorb to sediment and suspended organic matter and it may bioconcentrate in fish and aquatic organisms. Hydrolysis of 2-ethylhexyl acetate in aquatic systems is not expected to be a significant process except under basic conditions of pH >9.
