Regarding photodegradation, approximately 76% of the test material was photodegraded within 24 hours upon exposure to fluorescent light (lamda 300 and 360 nm) in the Fujiki test. Nitroethane does not hydrolyze in water under environmental conditions of temperature and pH. Nitroethane was not readily biodegradable in OECD301D test but did show evidence of biodegradation in a method developed by the GSF Institute for Ecological Chemistry.
The bioaccumulation potential of nitroethane is low based on a log Kow of 0.162.
Mackay Level I predicted equilibrium distribution among air, water, soil, and sediments was examined. This substance has high water solubility, moderate vapor pressure, and low log Kow. In the absence of advective and reactive processes, these physical properties dictate that the substance will be distributed primarily among the air and water compartments at equilibrium. The substance has a low potential for adsorption to soil or sediments, and moderate potential to volatilize from water.
Mackay Level III predicted distribution among air, water, soil, and sediments was examined. This substance has high water solubility, moderate vapor pressure, and low log Kow. The substance therefore has a low potential for adsorption to soil or sediments, and moderate potential to volatilize from water or soil to the atmosphere. If released to air (the most probable emission route), nitroethane will remain primarily in the atmospheric compartment, with some deposition to surface water and soil. Nitroethane is slowly reacted in the atmosphere, and therefore advection is expected to be the dominant process affecting atmospheric fate. If released directly to water, the substance will remain dissolved in water and is expected to be ultimately biodegraded. If released to soil, nitroethane will be primarily dissolved in soil pore water (groundwater), and is expected to be ultimately biodegraded.
