Taking an estimated Koc value of 650 based on a structure estimation method, pentarythritol tetranitrate is expected to have low mobility in soil. Henry's constant has also been estimated on 1.3x10 -9 atm-cu m/mole. This value and a water solubility of 43 mg/l conclude that volatilization of pentaerythritol pentanitrate from moist soil surfaces/ water surfaces is not expected to be an important fate process. Due to its natural state, solid, its vapour pressure is negligible and therefore pentaerythritol tetranitrate is not expected to volatilize from dry soil surfaces. It is also a nitrogen source for microbial cultures isolated from soil and sewage sludge, suggesting that pentaerythritol pentanitrate may biodegrade in the terrestrial environment.
An estimated BCF of 17, from an estimated log Kow of 2.4 and a regression-derived equation, suggests the potential for bioconcentration in aquatic organisms is low.
