SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

The oxidation of mustard gas can result in the formation of mustard sulfoxide; the sulfoxide can further react forming vinyl sulfoxide(1). Therefore, vinyl sulfoxide may be formed during the chemical decontamination of mustard gas(1) and released during this process to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 16(SRC), determined from a structure estimation method(2), indicates that vinyl sulfoxide is expected to have very high mobility in soil(SRC). Under anaerobic conditions in soil, vinyl sulfoxide may be microbially reduced to the sulfide(5). Volatilization of vinyl sulfoxide from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.9X10-7 atm-cu m/mole(SRC), using a fragment constant estimation method(3). The potential for volatilization of vinyl sulfoxide from dry soil surfaces may exist based upon an estimated vapor pressure of 1.6 mm Hg(SRC), determined from a fragment constant method(4).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 16(SRC), determined from a structure estimation method(2) and a regression-derived equation(3), indicates that vinyl sulfoxide 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 of 3.9X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Under anaerobic conditions in sediment, vinyl sulfoxide may be microbially reduced to the sulfide(7). According to a classification scheme(5), an estimated BCF of 3(SRC), from an estimated log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low.|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), vinyl sulfoxide, which has an estimated vapor pressure of 1.6 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 vinyl sulfoxide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone molecules(SRC); the half-lives for these reactions in air are estimated to be 3 hours and 3 days, respectively(SRC), calculated from their rate constants of 1.1X10-10 and 3.5X10-18 cu cm/molecule-sec at 25 °C(SRC), respectively, determined using structure estimation methods(3).

The rate constant for the vapor-phase reaction of vinyl sulfoxide 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 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Vinyl sulfoxide may also react with atmospheric ozone with an estimated rate constant for this reaction of 3.5X10-18 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 3 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(1). Vinyl sulfoxide is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(2).

An estimated BCF of 3 was calculated for vinyl sulfoxide(SRC), using an estimated log Kow of -0.5(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.

Using a structure estimation method based on molecular connectivity indices(1), the Koc for vinyl sulfoxide can be estimated to be 16(SRC). According to a classification scheme(2), this estimated Koc value suggests that vinyl sulfoxide is expected to have very high mobility in soil.

The Henry's Law constant for vinyl sulfoxide is estimated as 3.9X10-7 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that vinyl sulfoxide is expected to be essentially nonvolatile from water surfaces(2). Vinyl sulfoxide's Henry's Law constant(1) indicates that volatilization from moist soil surfaces is not expected(SRC). The potential for volatilization of vinyl sulfoxide from dry soil surfaces may exist(SRC) based upon an estimated vapor pressure of 1.6 mm Hg(SRC), determined from a fragment constant method(3).

Occupational exposure to vinyl sulfoxide may occur through inhalation and dermal contact with this compound at locations where mustard gas is decontaminated. (SRC)

The oxidation of mustard gas can result in the formation of mustard sulfoxide; the sulfoxide can further react forming vinyl sulfoxide(1).
