AQUATIC FATE: Based on a classification scheme (1), an estimated Koc value of 100 (SRC), determined from a log Kow of 1.21 (2) and a regression-derived equation (3), indicates that diethyl carbonate is not expected to adsorb to suspended solids and sediment in water (SRC). Volatilization from water surfaces is expected to be an important fate process (3) based upon an estimated Henry's Law constant of 8.9X10-5 atm-cu m/mole (SRC), calculated from a vapor pressure of 10.8 mm Hg (4) and water solubility of 18,800 mg/l (5). Using this Henry's Law constant and an estimation method (3), volatilization half-lives for a model river and model lake are 8 hours and 8 days, respectively (SRC). Diethyl carbonate may undergo hydrolysis in water since esters are susceptible to hydrolysis (3). Although no biodegradation data for diethyl carbonate was located, chemically similar short alkyl chain esters have been shown to biodegrade (6). According to a classification scheme (7), an estimated BCF of 2 (SRC), from its log Kow (2) and a regression-derived equation (8), suggests the potential for bioconcentration in aquatic organisms is low (SRC).

Further remarks from the author of this substance-specific data set:

The substance is readily biodegradable according to a study of good quality generated by Bayer. Furthermore, unproblematic substances are generated when diethyl carbonate hydrolyses: carbon dioxide and ethanol.
