Chemical Weapons/Chemical Weapons Precursors chemical material that, if stolen or diverted, can be converted into weapons using simple chemistry, equipment, or techniques.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Principles and methods for destruction of chemical weapons: ... "Destruction of chemical weapons" means a process by which chemicals are converted in an essentially irreversible way to a form unsuitable for production of chemical weapons, and which in an irreversible manner renders munitions and other devices unusable as such. ... Each ... /nation/ shall determine how it shall destroy chemical weapons, except that the following processes may not be used: dumping in any body of water, land burial or open-pit burning. It shall destroy chemical weapons only at specifically designated and appropriately designed and equipped facilities. ... Each ... /nation/ shall ensure that its chemical weapons destruction facilities are constructed and operated in a manner to ensure the destruction of the chemical weapons; and that the destruction process can be verified under the provisions of this Convention.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1 for the neutral species(SRC), determined from a structure estimation method(2), indicates that ethyldiethanolamine is expected to have very high mobility in soil(SRC). The estimated pKa of ethyldiethanolamine is 8.7(3), indicating that this compound will partially exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of ethyldiethanolamine from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.1X10-10 atm-cu m/mole for the neutral species(SRC), using a fragment constant estimation method(5). Ethyldiethanolamine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.5X10-3 mm Hg(SRC), determined from a fragment constant method(6). A 4% of theoretical BOD using activated sludge in the Japanese MITI test(7) suggests that biodegradation is not an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1 fro the neutral species(SRC), determined from a structure estimation method(2), indicates that ethyldiethanolamine is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant for the neutral species of 1.1X10-10 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). An estimated pKa of 8.7(5) indicates ethyldiethanolamine will exist partially in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(6). According to a classification scheme(6), and BCF values of <1.1 and <11(7), suggest the potential for bioconcentration in aquatic organisms is low(SRC). A 4% of theoretical BOD using activated sludge in the Japanese MITI test(7) suggests that biodegradation is not an important environmental fate process in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethyldiethanolamine, which has an estimated vapor pressure of 2.5X10-3 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyldiethanolamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 3.7 hrs(SRC), calculated from its rate constant of 1.1X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Ethyldiethyethanolamine does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of ethyldiethanolamine can be estimated to be 1 for the neutral species(SRC). According to a classification scheme(2), this estimated Koc value suggests that ethyldiethanolamine is expected to have very high mobility in soil. The pKa of ethyldiethanolamine is estimated as 8.7(3), indicating that this compound will partially exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

AEROBIC: Ethyldiethanolamine, present at 100 mg/L, reached 4% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Ethyldiethanolamine, added at daily increments of 15 mg/L, reached 3.60% of its TOD during a five day biochemical oxygen demand test using an acclimated sewage culture(2).

BCF values of <1.1 (0.5 mg/L) and <11 (0.05 mg/L) were reported in carp which were exposed to ethyldiethanolamine over a 6-week period(1). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).

The Henry's Law constant for the neutral form of ethyldiethanolamine is estimated as 1.1X10-10 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that ethyldiethanolamine is expected to be essentially nonvolatile from water surfaces(2). Ethyldiethanolamine's Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to occur(SRC). Ethyldiethanolamine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.5X10-3 mm Hg(SRC), determined from a fragment constant method(3).

The rate constant for the vapor-phase reaction of ethyldiethanolamine with photochemically-produced hydroxyl radicals has been estimated as 1.1X10-10 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 3.7 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Ethyldiethanolamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Ethyldiethanolamine does not contain chromophores that absorb at wavelengths >290 nm(3) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

Ethyldiethanolamine's production and use as a solvent and detergent may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 2.5x10-3 mm Hg at 25 °C indicates ethydiethanolamine will exist solely as a vapor in the atmosphere. Vapor-phase ethyldiethanolamine will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.7 hrs. Ethyldiethanolamine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, ethyldiethanolamine is expected to have very high mobility based upon an estimated Koc of 1 for the neutral species. The estimated pKa of ethyldiethanolamine is 8.7, indicating that this compound will partially exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.1X10-10 atm-cu m/mole for the neutral species. A 4% of theoretical BOD using activated sludge in the Japanese MITI test suggests that biodegradation is not an important environmental fate process in soil or water. If released into water, ethyldiethanolamine is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant for the neutral species. BCF values of <1.1 and <11 suggest bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to ethyldiethanolamine may occur through dermal contact with this compound at workplaces where ethyldiethanolamine is produced or used. (SRC)
