Leaching in soil is possible. Occupational exposure to 2-hydroxypropanenitrile can occur through inhalation of vapor and dermal contact. There are no data available to suggest that the general population is exposed to 2-hydroxypropanenitrile. One screening study has demonstrated that 2-hydroxypropanenitrile is readily biodegradable in Ohio River water . Based on this study, microbial degradation in soil is likely to be an important removal mechanism.
Insufficient data are available to predict the importance of other degradation processes in soil.
2-Hydroxypropanenitrile is miscible in water which suggests that leaching in soil is likely to occur. One screening study has demonstrated that 2-hydroxypropanenitrile is readily biodegradable in Ohio River water . Insufficient data are available to predict the importance of other degradation processes in water. Aquatic bioconcentration, volatilization, and adsorption to sediment are not expected to be environmentally important. Using measured vapor pressures of 17 mm Hg at 90 deg C and 30 mm Hg at 102 deg C , the vapor pressure of 2-hydroxypropanenitrile can be extrapolated to 0.28 mm Hg at 25 deg C using the Antoine relationship.
